Description

These single-port globe-style valves have cage guiding, clamped seat rings, and push-down-to-close valve plug action.

Valve configurations are as follows:

EWD: Balanced valve plug with metal-to-metal seating for all general applications over a wide range of pressure drops

and temperatures.

C-seal trim is available for EWD valves, CL300 and CL600, in sizes NPS 6x4x2-1/2, 6x4, 8x4, 8x6, 12x6, 10x8, and 12x8.

With C-seal trim, a balanced valve can achieve high-temperature, Class V shutoff. Because the C-seal plug seal is

formed from metal (N07718 nickel alloy) rather than an elastomer, a valve equipped with the C-seal trim can be

appliedinprocesseswithafluidtemperatureofupto593_C (1100_F), provided other material limits are not

exceeded.

EWS: Unbalanced valve plug with metal-to-metal or optional metal-to-PTFE seating for all general applications

requiring better shutoff capabilities than can be obtained with the EWD valve.

EWT: Balanced valve plug with either metal-to-PTFE seating (standard for all except Cavitrol III cages) for stringent

shutoff requirements or metal-to-metal seating (standard for Cavitrol III cages, optional for all others) for higher

temperatures.

Control valves with WhisperFlo cages (figure 2) provide additional attenuation for aerodynamic noise in very

demanding vapor or gas applications with high-pressure drops. A WhisperFlo cage with an appropriately sized valve

body is designed to reduce the noise level up to -40 dBA. For special applications, -50 dBA attenuation can be

achieved.

Specifications

Typical specifications for these valves are shown in table 1.

Installation

WARNING

Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal

injury.

Personal injury or equipment damage caused by sudden release of pressure or bursting of parts may result if the valve

assembly is installed where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To

avoid such injury or damage, provide a relief valve for overpressure protection as required by government or accepted

industry codes and good engineering practices.

Instruction Manual

D100399X012

EW Valve

September 2014

Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this

instruction manual.

CAUTION

When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,

pressure drop and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve

materials with process media rests solely with the purchaser and end-user. Since some body/trim material combinations

are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first

contacting your Emerson Process Management sales office.

Before installing the valve, inspect the valve and pipelines for any damage and any foreign material which may cause

product damage.

CAUTION

If hoisting the valve, use a nylon sling to protect the surfaces. Carefully position the sling to prevent damage to the actuator

tubing and any accessories. Also, take care to prevent people from being injured in case the hoist or rigging slips

unexpectedly. Refer to table 4 for valve assembly weights. Be sure to use adequately sized hoists and chains or slings to

handle the valve.

1. Before installing the valve, inspect the valve body cavity and associated equipment for any damage and any foreign

material.

2. Make certain the valve body interior is clean, that pipelines are free of foreign material, and that the valve is

orientedsothatpipelineflowisinthesamedirectionasthearrowonthesideofthevalve.

3. Install the control valve assembly in any orientation unless limited by seismic criteria. However, the normal method

is with the actuator vertical above the valve. Other positions may result in uneven valve plug and cage wear and in

improper operation. With some valves, the actuator may also need to be supported when it is not vertical. For more

information, consult your Emerson Process Management sales office.

Note

If installing a valve with small internal flow passages, such as with WhisperFlo, Whisper Trim, or Cavitrol cages, consider installing

an upstream strainer to prevent the lodging of particles in these passages. This is especially important if the pipeline cannot be

thoroughly cleaned or if the flowing medium is not clean.

Instruction Manual

D100399X012

EW Valve

September 2014

4. Use accepted piping and welding practices when installing the valve in the line. For flanged valve bodies, use a

suitable gasket between the valve body and pipeline flanges.

CAUTION

Depending on valve body materials used, post weld heat treating may be required. If so, damage to internal elastomeric

and plastic parts, as well as internal metal parts is possible. Shrink-fit pieces and threaded connections may also loosen. In

general, if post weld heat treating is to be performed, remove all trim parts. Contact your Emerson Process Management

sales office for additional information.

5. With a leak-off bonnet construction, remove the pipe plugs (keys 14 and 16, figure 21) from the bonnet to hook up

the leak-off piping. If continuous operation is required during inspection or maintenance, install a three-valve

bypass around the control valve assembly.

6. If the actuator and valve are shipped separately, refer to the actuator mounting procedure in the appropriate

actuator instruction manual.

WARNING

Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing

might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any

additional measures that must be taken to protect against process media.

Valves with ENVIRO-SEAL live-loaded packing or HIGH-SEAL live-loaded packing will not require this initial

re-adjustment. See Fisher instruction manuals, ENVIRO-SEAL Packing System for Sliding-Stem Valves, D101642X012,

or HIGH-SEAL Live-Loaded Packing System, D101453X012, (as appropriate), for packing instructions. If you wish to

convert your present packing arrangement to ENVIRO-SEAL packing, refer to the retrofit kits listed in the parts kit

sub-section near the end of this manual.

Inverted Globe Valve Applications (Actuator below valve)

Due to space restrictions in your application, you may be required to mount the valve/actuator assembly in an inverted

orientation, with the actuator positioned below the valve. If so, the following procedures will help you with

disassembly and assembly techniques.

WARNING

Avoid personal injury or property damage caused by components dropping.

With the valve/actuator upside down, components may drop during disassembly or assembly. Be careful not to position

yourself below the valve in the path of falling parts.

As the bonnet/plug/cage is lowered from the valve body, the center of gravity will be above the lifting points. Take care to

prevent the assembly from tipping over as it is lowered. Either leave the actuator attached to the plug and bonnet, attach

straps to the stem, or provide other means to prevent tipping.

2. Provideadequatesupporttothebonnetwhileremovingthebonnetnuts.

3. Be aware that the bonnet/plug/cage may tip over as they are lowered from the valve body. Make provision to

prevent tipping.

4. Be aware that the cage and seat ring may not come out with the bonnet and plug/stem assembly. If this occurs,

make provision to support these parts, as they may fall out unexpectedly.

Assembly

1. Start this assembly procedure with the plug/stem assembly already installed in the bonnet.

2. Put the gaskets and cage onto the bonnet and plug.

3. Place the seat ring with the seat ring gasket onto the cage, if applicable with the valve design.

4. Raise this bonnet/plug/cage assembly up into the valve body. Make provision to prevent tipping of these parts as

they are being raised into the valve body.

5. Torque the bonnet nuts.

6. Mount the actuator.

Maintenance

Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance

frequency depends on the severity of service conditions. This section includes instructions for packing lubrication,

packing maintenance, trim maintenance, lapping metal seats, and ENVIRO-SEAL bellows seal bonnet replacement. All

maintenance operations may be performed with the valve in the line.

WARNING

Avoid personal injury or property damage from sudden release of process pressure. Before performing any maintenance

operations:

DDo not remove the actuator from the valve while the valve is still pressurized.

DAlways wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

DDisconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

DUse bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

on both sides of the valve. Drain the process media from both sides of the valve.

DVent the pneumatic actuator loading pressure and relieve any actuator spring precompression.

DUse lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

DThe valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when

loosening the packing box pipe plug.

DCheck with your process or safety engineer for any additional measures that must be taken to protect against process

media.

CAUTION

Follow instructions carefully to avoid damaging the product surfaces, which could result in damage to the product.

Instruction Manual

D100399X012

Note

Whenever a gasket seal is disturbed by removing or shifting gasketed parts, install a new gasket upon reassembly. This is necessary

to ensure a good gasket seal because the used gasket may not seal properly.

Packing Lubrication

CAUTION

Do not lubricate graphite packing. Graphite packing is self-lubricated. Additional lubrication may result in slip-stick

movement of the valve.

Note

ENVIRO-SEAL or HIGH-SEAL packing does not require lubrication.

WARNING

To avoid personal injury or property damage resulting from fire or explosion, do not lubricate packing used in oxygen

service or in processes with temperatures over 260_C (500_F).

If a lubricator or lubricator/isolating valve (figure 3) is provided for PTFE/composition or other packings that require

lubrication, it will be installed in place of the pipe plug (key 14, figure 21). Use a good quality silicon-base lubricant. Do

not lubricate packing used in oxygen service or in processes with temperatures over 260_C(500_F). To operate the

lubricator, simply turn the cap screw clockwise to force the lubricant into the packing box. The lubricator/isolating

Packing Maintenance

Note

For valves with ENVIRO-SEAL live-loaded packing, see the Fisher instruction manual, ENVIRO-SEAL Packing System for Sliding-Stem

Valves, D101642X012, for packing instructions. For valves with HIGH-SEAL live-loaded packing, see the Fisher instruction manual,

HIGH-SEAL Live-Loaded Packing System, D101453X012, for packing instructions.

Key numbers refer to figure 4 for PTFE V-ring packing and to figure 5 for PTFE/composition packing, unless otherwise

indicated.

For spring-loaded single PTFE V-ring packing, the spring (key 8, figure 4) maintains a sealing force on the packing. If

leakage is noted around the packing follower (key 13, figure 4), check to be sure the shoulder on the packing follower

is touching the bonnet. If the shoulder is not touching the bonnet, tighten the packing flange nuts (key 5, figure 21)

until the shoulder is against the bonnet. If leakage cannot be stopped in this manner, go to the Replacing Packing

procedure.

If there is undesirable packing leakage with other than spring-loaded packing, first try to limit the leakage and

establish a stem seal by tightening the packing flange nuts.

If the packing is relatively new and tight on the stem and if tightening the packing flange nuts does not stop the

leakage, the valve stem may be worn or nicked so that a seal cannot be made. The surface finish of a new valve stem is

critical for making a good packing seal. If the leakage comes from the outside diameter of the packing, the leakage

may be caused by nicks or scratches around the packing box wall. If performing any of the following procedures,

inspect the valve stem and packing box wall for nicks and scratches.

Replacing Packing

WARNING

Avoid personal injury or property damage from sudden release of process pressure. Before performing any maintenance

operations:

Instruction Manual

D100399X012

EW Valve

September 2014

DDo not remove the actuator from the valve while the valve is still pressurized.

DAlways wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

DDisconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

DUse bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

on both sides of the valve. Drain the process media from both sides of the valve.

DVent the pneumatic actuator loading pressure and relieve any actuator spring precompression.

DUse lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

DThe valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when

loosening the packing box pipe plug.

DCheck with your process or safety engineer for any additional measures that must be taken to protect against process

media.

1. Isolatethecontrolvalvefromthelinepressure,releasepressure from both sides of the valve, and drain the process

media from both sides of the valve. If using a power actuator, also shut-off all pressure lines to the power actuator

andreleaseallpressurefromtheactuator.Uselock-outprocedurestobesurethattheabovemeasuresstayin

effect while you work on the equipment.

2. Disconnect the operating lines from the actuator and any leak-off piping from the bonnet. Disconnect the stem

connector, and then remove the actuator from the valve by unscrewing the yoke locknut (key 15, figure 21) or the

hex nuts (key 26, figure 21).

3. Loosen the packing flange nuts (key 5, figure 21) so that the packing is not tight on the valve stem. Remove any

travel indicator parts and stem locknuts from the valve stem threads.

WARNING

To avoid personal injury or property damage caused by uncontrolled movement of the bonnet, loosen the bonnet by

following the instructions in the next step. Do not remove a stuck bonnet by pulling on it with equipment that can stretch

or store energy in any other manner. The sudden release of stored energy can cause uncontrolled movement of the bonnet.

Note

The following step also helps to provide additional assurance that the valve body fluid pressure has been relieved.

4. Hex nuts (key 16, figure 22, 23 or 24) attach the bonnet (key 1, figure 21) to the valve body (key 1, figure 22, 23 or

24). Loosen these nuts approximately 3 mm (1/8 inch). Then loosen the body-to-bonnet gasketed joint by either

rocking the bonnet or prying between the bonnet and valve body. Work the prying tool around the bonnet until the

bonnet loosens. If no fluid leaks from the joint, proceed with bonnet removal as described in the following steps.

CAUTION

To avoid damage to the seating surface caused by the valve plug and stem assembly dropping from the bonnet after being

lifted part way out, temporarily install a valve stem locknut on the valve stem when lifting the bonnet. The locknut

prevents the valve plug and stem assembly from dropping out of the bonnet.

5. Completely remove the hex nuts (key 16) and carefully lift the bonnet off the valve body.

Instruction Manual

D100399X012

EW Valve

September 2014

6. Remove the locknut and separate the valve plug and stem from the bonnet. Set the parts on a protective surface to

prevent damage to gasket or seating surfaces.

7. Remove the bonnet gasket (key 10, figure 22 through 24), and cover the opening in the valve body to protect the

gasket surface and prevent foreign material from getting into the valve body cavity.

8. Remove the packing flange nuts, packing flange, upper wiper, and packing follower (keys 5, 3, 12, and 13, figure

21). Carefully push out all the remaining packing parts from the valve side of the bonnet using a rounded rod or

other tool that will not scratch the packing box wall. Clean the packing box and the metal packing parts.

9. Inspect the valve stem threads and packing box surfaces for any sharp edges that might cut the packing. Scratches

or burrs could cause packing box leakage or damage to the new packing. If the surface condition cannot be

improved by light sanding, replace the damaged parts by following the appropriate steps in the Trim Maintenance

procedure.

10. Remove the covering protecting the valve cavity and install a new bonnet gasket (key 10, figure 22 through 24),

making sure the gasket seating surfaces are clean and smooth. Place the stem and valve plug into the valve body

and slide the bonnet over the stem and onto the stud bolts (key 15, figure 22, 23, or 24).

Note

Proper performance of the tightening procedures in step 11 compresses the spiral wound gasket (key 12, figure 22 through 23) or

load ring (key 26, figure 24) enough to both load and seal the seat ring gasket (key 13, figure 22, 23 or 24). It also compresses the

outer edge of the bonnet gasket (key 10, figure 22 through 24) enough to seal the body-to-bonnet joint.

The proper bolting procedures in step 11 include--but are not limited to--ensuring that bolting threads are clean, and evenly

tightening the nuts onto the studs in a criss-cross pattern. Because of the bolt-up characteristics of spiral wound gaskets,

tightening one nut may loosen an adjacent nut. Repeat the criss-cross tightening pattern several times until each nut is tight and

the body-to-bonnet seal is made. When the operating temperature has been reached, perform this torquing procedure once

again.

Note

Stud(s) and nut(s) should be installed such that the manufacturer's trademark and material grade marking is visible, allowing easy

comparison to the materials selected and documented in the Emerson/Fisher serial card provided with this product.

WARNING

Personal injury or damage to equipment could occur if improper stud and nut materials or parts are used. Do not operate or

assemble this product with stud(s) and nut(s) that are not approved by Emerson/Fisher engineering and/or listed on the

serial card provided with this product. Use of unapproved materials and parts could lead to stresses exceeding the design

or code limits intended for this particular service. Install studs with the material grade and manufacturer's identification

mark visible. Contact your Emerson Process Management representative immediately if a discrepancy between actual

parts and approved parts is suspected.

11. Lubricate the bolting (not necessary if factory pre-lubricated stud bolt nuts are used) and install it, using proper

bolting procedures during tightening so that the body-to-bonnet joint will withstand test pressures and application

service conditions. Use the bolt torques in table 5 as guidelines.

12. Install new packing and the metal packing box parts according to the appropriate arrangement in figure 4, 5, or 6.

Place a smooth-edged pipe over the valve stem and gently tap each soft packing part into the packing box.

13. Slide the packing follower, upper wiper, and packing flange (keys 13, 12, and 3, figure 21) into position. Lubricate

the packing flange studs (key 4, figure 21) and the faces of the packing flange nuts (key 5, figure 21). Install the

packing flange nuts.

14. For spring-loaded PTFE V-ring packing, tighten the packing flange nuts until the shoulder on the packing follower

(key 13, figure 21) contacts the bonnet.

For graphite packing, tighten the packing flange nuts to the maximum recommended torque shown in table 6. Then,

loosen the packing flange nuts, and retighten them to the recommended minimumtorqueshownintable6.

For ENVIRO-SEAL or HIGH-SEAL live-loaded packing, refer to the note at the beginning of the Packing Maintenance

section.

For other packing types, tighten the packing flange nuts alternately in small equal increments until one of the nuts

reaches the minimum recommended torque shown in table. Then, tighten the remaining flange nuts until the packing

flange is level and at a 90-degree angle to the valve stem.

15. Mount the actuator on the valve assembly, and reconnect the actuator and valve stem according to the procedure

in the appropriate actuator instruction manual.

Trim Maintenance

WARNING

Avoid personal injury or property damage from sudden release of process pressure. Before performing any maintenance

operations:

DDo not remove the actuator from the valve while the valve is still pressurized.

DAlways wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

DDisconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

DUse bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

on both sides of the valve. Drain the process media from both sides of the valve.

DVent the pneumatic actuator loading pressure and relieve any actuator spring precompression.

DUse lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

DThe valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when

loosening the packing box pipe plug.

DCheck with your process or safety engineer for any additional measures that must be taken to protect against process

media.

CAUTION

In the following applicable procedures, to avoid damaging parts, do not grip the bellows shroud or other parts of the

stem/bellows assembly. Grip only the flat areas on the stem where it extends out of the top of the bellows shroud.

For C-seal construction, see the appropriate C-seal sections in this instruction manual.

Except where indicated, key numbers in this section are referenced in figure 22 for EWD constructions, figure 22 for

restricted trim detail, figure 23 for EWS constructions, and figure 24 for EWT constructions. Refer to figures 26 and 27

for Cavitrol III, figure 27 for Whisper Trim III, and figure 29 for WhisperFlo construction.

Trim Removal

1. Remove the actuator and the bonnet according to steps 1 through 5 of the Replacing Packing procedure.

WARNING

Avoid personal injury or property damage from valve or packing leakage.

When lifting the valve plug stem (key 7) and attached valve plug (key 2) out of the valve, be certain that the cage (key 3)

remains in the valve (key 1). This will prevent cage damage that might be caused by the cage dropping back into the valve

after being lifted part way out.

Use care to avoid damaging gasket sealing surfaces.

Each graphite piston ring (key 6) in an EWD valve is brittle and in two pieces. Use care to avoid damage to the piston ring(s)

caused by dropping or rough handling.

Any damage to the gasket sealing surfaces could cause the valve to leak. The surface finish of the valve stem (key 7) is

criticalformakingagoodpackingseal.Theinsidesurfaceofthecageorcage/baffleassembly(key3)orcageretainer(key

31) is critical for smooth operation of the valve plug and for making a seal with the piston ring (key 6) or seal ring (key 28).

The seating surfaces of the valve plug (key 2) and the seat ring (key 9) on a metal-seat construction are critical for tight

shutoff. Protect these parts accordingly while disassembling the trim.

2. Remove the packing flange nuts, packing flange, upper wiper, and packing follower (keys 5, 3, 24, and 25, figure

21). Carefully push out all the remaining packing parts from the valve side of the bonnet using a rounded rod or

other tool that will not scratch the packing box wall. Clean the packing box and the metal packing parts.

3. Inspect the valve stem threads and packing box surfaces for any sharp edges which might cut the packing.

Scratches or burrs could cause packing box leakage or damage to the new packing. If the surface condition cannot

be improved by light sanding, replace the damaged parts.

4. Remove the load ring (key 26) from an NPS 10x8 or 12x8 valve or the cage adaptor (key 4) from any restricted-trim

valve through NPS 8x4, and wrap it for protection.

5. On a 102 mm (4-inch) travel valve with Whisper Trim I cage or on any NPS 8x6 or 12x6 valve with Whisper Trim III

cage, remove the bonnet spacer (key 32) and bonnet gasket (key 10) on top of the spacer. Then on any

construction with a cage retainer (key 31), remove the cage retainer and its associated gaskets. A Whisper Trim III

cage retainer has two 3/8-inch - 16 UNC tappings in which screws or bolts can be installed for lifting.

6. Remove the cage or cage/baffle assembly (key 3) and the associated gaskets (keys 10, 11, and 12). With

full-capacity constructions that have FGM gasket sets, a shim (key 53) is used instead of the cage gasket (key 11). If

retainer (key 21). A CL900 NPS 8x6 EWT construction with Cavitrol III cage has its spiral wound gasket (key 12) on

thesideoftheseatringoppositetheseatringgasket.

8. For TSO (tight shutoff trim) constructions, perform the following steps (refer to figures 7 and 8):

DRemove the piston ring, anti-extrusion rings, backup ring, and retainer.

DRemove the set screws that lock the outer plug to the inner plug.

DUsing a strap wrench or similar tool, unscrew the outer plug from the inner plug. Do not damage the outer plug

guide surfaces.

DRemove the protected soft seat seal.

DInspect the parts for damage and replace if needed.

9. For all constructions, inspect parts for wear or damage that would prevent proper operation of the valve. Replace or

repair trim parts according to the following procedures for lapping metal seats or other valve plug maintenance

procedures, as appropriate.

Lapping Metal Seats

CAUTION

To avoid damaging the ENVIRO-SEAL bellows seal bonnet assembly, do not attempt to lap the metal seating surfaces. The

design of the assembly prevents rotation of the stem and any forced rotation will damage internal components of the

ENVIRO-SEAL bellows seal bonnet.

Except with respect to the ENVIRO-SEAL Bellows Seal Bonnet assembly, with metal seat constructions, seating surfaces

of the valve plug and seat ring (keys 2 and 9, figures 24 through 26) can be lapped for improved shutoff. (Deep nicks

should be machined out rather than ground out.) Use a good quality lapping compound of a mixture of 280 to

600-grit. Apply the compound to the bottom of the valve plug.

Assemble the valve to the extent that the cage (and cage retainer and bonnet spacer, if used) is in place and the

bonnetisboltedtothevalve.Asimplehandlecanbemadefromapieceofstrapironlockedtothevalveplugstem

with nuts. Rotate the handle alternately in each direction to lap the seats. After lapping, remove the bonnet, and clean

the seat surfaces. Completely assemble the valve as described in the Trim Replacement portion of the Trim

Maintenance section, and test the valve for shutoff. Repeat the lapping procedure if leakage is still excessive.

Valve Plug Maintenance

Except where indicated, key numbers in this section are referenced in figure 22 for EWD valve plugs, figure 23 for EWS

valve plugs, and figure 24 for EWT valve plugs.

CAUTION

If replacing the piston ring (key 6) or seal ring (key 28), be careful not to scratch the surfaces of the ring groove in the valve

plug or any of the surfaces of the replacement ring, or the replacement ring may not seal properly.

1. With the valve plug (key 2) removed, according to the Trim Removal section, proceed as appropriate:

Instruction Manual

D100399X012

EW Valve

September 2014

For the EWD carbon-filled PTFE piston ring, the ring is split in one place. If there is visible damage, spread the ring

slightly, and remove it from the groove in the valve plug. To install a carbon-filled PTFE piston ring, spread the ring

apart slightly at the split, and install it over the stem and into the groove in the valve plug. The open side must face

along the stem, depending on flow direction, as shown in figure 22.

For each EWD graphite piston ring, the ring can be easily removed since it is in two pieces. A new graphite piston ring is

furnished as a complete ring. Use a vise with smooth or taped jaws to break this replacement ring into halves. Place the

new ring in the vise so that the jaws will compress the ring into an oval. Slowly compress the ring until it snaps on both

sides. If one side snaps first, do not try to tear or cut the other side. Instead, keep compressing the ring until the other

side snaps. Be sure to match the broken ends when installing the ring in the valve plug groove.

For the EWT two-piece seal ring, the ring cannot be reused as it is a closed ring, which must be pried and/or cut from

the groove. Then the elastomeric backup ring (key 29) can be spread slightly and removed.

To install a new two-piece seal ring, apply a general purpose silicone-base lubricant to both the backup ring and seal

ring(keys29and28).Placethebackupringoverthestem(key7)andintothegroove.Placethesealringoverthetop

edge of the valve plug (key 2) so that it enters the groove on one side of the valve plug. Slowly and gently stretch the

sealring,andworkitoverthetopedgeofthevalveplug.ThePTFEmaterialinthesealringmustbepermittedtimeto

cold-flow during the stretching procedure; so avoid jerking sharply on this ring. Stretching the seal ring over the valve

plug may make it seem unduly loose when in the groove, but it will contract to its original size after insertion into the

cage.

For the EWT spring-loaded seal ring, the ring used on a valve plug having a 136.5 mm (5.375 inch) or less port

diameter may be removed undamaged by first working the retaining ring (key 27) off with a screwdriver. Then

carefully slide the metal backup ring (key 29) and seal ring (key 28) off the valve plug (key 2). The spring-loaded seal

ring used on a valve plug having a 178 mm (7-inch) or greater port diameter must be carefully pried and/or cut from its

groove. Therefore, it cannot be reused.

A spring-loaded seal ring must be installed so that its open side faces toward either the top or the bottom of the valve

plug, depending on flow direction, as shown in view A of figure 24. To install a spring-loaded seal ring on a valve plug

with a 136.5 mm (5.375 inch) or less port diameter, slide the seal ring (key 28) onto the valve plug followed by the

metal backup ring (key 29). Then install the retaining ring (key 27) by inserting one end in the groove and, while

turning the plug, press the ring into the groove. Again, be careful not to scratch any surfaces of the ring or plug.

To install the seal ring on a valve plug with 178 mm (7-inch) or greater port diameter, lubricate it with a general

purpose silicone-base lubricant. Then gently stretch the seal ring, and work it over the top edge of the valve plug. The

PTFE material in the seal ring must be permitted time to cold-flow during the stretching procedure; so avoid jerking

sharply on the ring. Stretching the seal ring over the valve plug may make it seem unduly loose when in the groove,

but it will contract to its original size after insertion into the cage.

CAUTION

Never reuse an old stem or adaptor with a new valve plug. Using an old stem or adaptor with a new plug requires drilling a

new pin hole in the stem (or adaptor in case an ENVIRO-SEAL bellows seal bonnet is being used). This drilling weakens the

stem or adaptor and may cause failure in service. However, a used valve plug may be reused with a new stem or adaptor

except with Cavitrol III trim.

Note

The valve plug and valve plug stem for Cavitrol III trim are a matched set and must be ordered together. If the Cavitrol III valve plug

or valve plug stem is damaged, replace the entire assembly (key 2, figure 26 and 27).

3. To replace the adaptor (key 24, figure 21) on ENVIRO-SEAL bellows seal bonnets, place the plug stem assembly and

valve plug in a soft-jaw chuck or other type of vise so that the jaws grip a portion of the valve plug that is not a

seating surface. Drive out the pin (key 36, figure 21). Reverse the plug stem assembly and valve plug in the soft-jaw

chuck or vise. Grip the flat areas on the valve stem just below the threads for the actuator/stem connection.

Unscrew the valve plug/adaptor assembly (key 24, figure 21) from the valve stem assembly (key 20, figure 21).

4. Screw the new stem or adaptor into the valve plug. Tighten to the torque value given in table 7. Refer to table 7 to

select the proper drill size. Drill through the stem or adaptor, using the hole in the valve plug as a guide. Remove

Except where indicated, key numbers in this section are referenced in figure 22 for EWD constructions, figure 22 for

restricted trim detail, figure 23 for EWS construction, and figure 24 for EWT constructions. Refer to figures 26 and 27

for Cavitrol III, figure 28 for Whisper Trim III, and figure 29 for WhisperFlo constructions.

1. With a restricted-trim seat ring construction, install the adaptor gasket (key 14) and seat ring adaptor (key 5).

2. Install the seat-ring gasket (key 13), seat ring (key 9), or disk seat (key 22). With a PTFE-seat construction install the

disk and disk retainer (keys 21 and 23). With an NPS 8x6 CL900 EWT valve with Cavitrol III cage, install the spiral

wound gasket (key 12) on the seat ring.

3. Install the cage or cage/baffle assembly (key 3). Any rotational orientation of the cage or assembly with respect to

the valve is acceptable. A Whisper Trim III cage designated by level A3, B3, or C3 may be installed with either end

up.ThelevelD3cage/baffleassemblyorCavitrolIIIcageassembly,however,mustbeinstalledwiththeholepattern

end next to the seat ring. If a cage retainer (key 31) is to be used, place it on top of the cage.

4. For constructions other thanTSO(tightshutofftrim), slide the valve plug (key 2) and stem assembly or valve plug

and ENVIRO-SEAL bellows seal assembly into the cage. Make sure the piston ring or seal ring (key 6 or 28) is evenly

engaged in the entrance chamfer at the top of the cage (key 3) or cage retainer (key 31) to avoid damaging the ring.

5. For TSO (tight shutoff) trim constructions, perform the following steps (refer to figures 7 and 8).

DThread the outer plug onto the inner plug until the parts seat metal to metal, using a strap wrench or similar tool

that will not damage the outer plug guide surfaces.

Retrofit: Installing C-seal Trim

Note

Additional actuator thrust is required for a valve with C-seal trim. When installing C-seal trim in an existing valve, contact your

Emerson Process Management sales office for assistance in determining new actuator thrust requirements.

Assemble the new valve plug/retainer assembly (with C-seal plug seal) using the following instructions:

CAUTION

To avoid leakage when the valve is returned to service, use appropriate methods and materials to protect all sealing

surfaces of the new trim parts while assembling the individual parts and during installation in the valve body.

1. Apply a suitable high-temperature lubricant to the inside diameter of the C-seal plugseal.Also,lubricatethe

outside diameter of the valve plug where the C-seal plug seal must be pressed into the proper sealing position

(figure 9).

2. Orient the C-seal plug seal for correct sealing action based on the process fluid flow direction through the valve.

DThe open interior of the C-seal plug seal must face up in a valve with flow-up construction (figure 9).

DThe open interior of the C-seal plug seal must face down in a valve with flow-down construction (figure 9).

Note

An installation tool must be used to properly position the C-seal plug seal on the valve plug. A tool is available as a spare part from

Emerson Process Management or a tool could be manufactured following the dimensions given in figure 10.

3. Place the C-seal plug seal over the top of the valve plug and press the C-seal plug seal onto the plug using the C-seal

installation tool. Carefully press the C-seal plug seal onto the plug until the installation tool contacts the horizontal

CAUTION

To avoid excessive leakage and seat erosion, the valve plug must be initially seated with sufficient force to overcome the

resistance of the C-seal plug seal and contact the seat ring. You can correctly seat the valve plug by applying the full

actuator load. This force will adequately drive the valve plug to the seat ring, thus giving the C-seal plug seal a

predetermined permanent set. Once this is done, the plug/retainer assembly, the cage, and the seat ring become a

matched set.

With full actuator force applied and the valve plug fully seated, align the actuator travel indicator scale with the lower end

of valve travel. Refer to the appropriate actuator instruction manual for information on this procedure.

Replacement of Installed C-seal Trim

Trim Removal (C-seal Constructions)

1. Remove the valve actuator and bonnet following the appropriate instructions in the Replacing Packing section in

this manual.

CAUTION

To avoid leakage when the valve is returned to service, use appropriate methods and materials to protect all sealing

surfaces of the trim parts during maintenance.

Use caution when removing piston ring(s) and C-seal plug seal to avoid scratching any sealing surface.

CAUTION

Do not remove the valve stem from the plug/retainer assembly unless you are planning to replace the valve stem.

Never reuse an old valve stem with a new plug or reinstall a valve stem after it has been removed. Replacing a valve stem

requires drilling a new pin hole in the stem. This drilling weakens the stem and may cause failure in service. However, a

used valve plug may be reused with a new valve stem.

2. Remove the plug/retainer assembly (with C-seal plug seal), cage, and seat ring from the valve body following the

appropriate instructions in the Trim Removal section of this manual.

3. Locate the staked thread on top of the valve plug (figure 12). The staked thread secures the retainer. Use a drill with

a 1/8 inch bit to drill out the staked area of the thread. Drill approximately 1/8 inch into the metal to remove the

staking.

4. Locate the break between sections of the piston ring(s). Using an appropriate tool such as a flat-blade screwdriver,

carefully pry out the piston ring(s) fromthegroove(s)intheC-sealretainer.

5. After removing the piston ring(s), locate the 1/4-inch diameter hole in the groove. In a retainer with two piston ring

grooves,theholewillbefoundintheuppergroove.

6. Selectanappropriatetoolsuchasapunchandplacethetipofthetoolintotheholewiththebodyofthetoolheld

9. Replace or repair trim parts according to the following procedure for lapping metal seats, remachining metal seats,

or other valve plug maintenance procedures as appropriate.

Lapping Metal Seats (C-seal Constructions)

Before installing a new C-seal plug seal, lap the lower seating surface (valve plug to seat ring,

figure 13) following appropriate procedures in the Lapping Metal Seats section of this manual.

Remachining Metal Seats (C-seal Constructions)

See figure 14. A valve plug with a C-seal metal plug seal features two seating surfaces. One seating surface is found

wherethevalveplugcontactstheseatring. The second seating surface is found where the C-seal plug seal contacts

the upper seating surface in the cage. If you machine the seats on the seat ring and/or plug, you must machine an

equal dimension from the seating area in the cage.

CAUTION

If metal is removed from the seat ring and plug and a corresponding amount is not removed from the cage seating area, the

C-seal plug seal will be crushed as the valve closes and the C-seal retainer will strike the seating area of the cage, preventing

the valve from closing.
