Description
These single-port valves have cage guiding, quick-change trim, and balanced push-down-to-close valve plug action.
Valve configurations are as follows:
ED--Globe-style valve (figure 1) with metal-to-metal seating for all general applications over a wide variety of pressure
drops and temperatures.
EAD--Angle version of ED, used to facilitate piping or in applications where a self-draining valve is required.
C-seal trim is available for ED valves, CL150, 300, and 600, in NPS 2-1/2, 3, 4, 6, and 8. C-seal trim is available for EAD
valves, CL150, 300, and 600, in NPS 3, 4, and 6.
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
applied in processes with a fluid temperature of up to 593_C (1100_F), provided other material limits are not
exceeded.

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 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 over-pressure protection as required by government or accepted industry codes and
good engineering practices.
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.

1. Before installing the valve, inspect the valve 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
oriented so that pipeline flow is in the same direction as the arrow on the side of the valve.
3. The control valve assembly may be installed 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 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.
4. Use accepted piping and welding practices when installing the valve in the line. For flanged valves, use a suitable
gasket between the valve 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, all trim parts should be removed. 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 18) 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 the Fisher instruction manuals, ENVIRO-SEAL Packing System for Sliding-Stem Valves or HIGH-SEAL
Live-Loaded Packing System (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.

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, 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 or bursting of parts. Before performing
any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Disconnect 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.

4

Instruction Manual
D100390X012

ED Valve

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
from both sides of the valve. Drain the process media from both sides of the valve.
D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression.
D Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The 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.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.

Note
Whenever a gasket seal is disturbed by removing or shifting gasketed parts, install a new gasket during reassembly. This ensures a
good gasket seal because the used gasket may not seal properly.

Packing Lubrication
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 2) is provided for PTFE/composition or other packings that require
lubrication, it will be installed in place of the pipe plug (key 14, figure 18). Use a good quality silicon-based 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
valve operates the same way except open the isolating valve before turning the cap screw and then close the isolating
valve after lubrication is completed.

Packing Maintenance
Note
For valves with ENVIRO-SEAL packing, see the Fisher instruction manual, ENVIRO-SEAL Packing System for Sliding-Stem Valves,
D101642X012, for packing instructions.
For valves with HIGH-SEAL packing, see the Fisher instruction manual, HIGH-SEAL Live-Loaded Packing System, D101453X012, for
packing instructions.

Key numbers refer to figure 3 for PTFE V-ring packing and to figure 4 for PTFE/composition packing, unless otherwise
indicated.

LUBRICATOR/ISOLATING VALVE

For spring-loaded single PTFE V-ring packing, the spring (key 8, figure 3) maintains a sealing force on the packing. If
leakage is noted around the packing follower (key 13, figure 3), 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 18)
until the shoulder is against the bonnet. If leakage cannot be stopped in this manner, proceed 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
Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, 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, and release all pressure from the actuator. Use lock-out procedures to be sure that the above measures
stay in 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, then remove the actuator from the valve by unscrewing the yoke locknut (key 15, figure 18) or the hex
nuts (key 26, figure 18).

3. Loosen the packing flange nuts (key 5, figure 18) 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 provides additional assurance that the valve body fluid pressure has been relieved.

CAUTION
Avoid damaging the seating surface caused by the valve plug and stem assembly dropping from the bonnet (key 1, figure
18) after being lifted part way out. When lifting the bonnet, temporarily install a valve stem locknut on the valve stem. This
locknut will prevent the valve plug and stem assembly from dropping out of the bonnet.
If the cage starts to lift with the bonnet, tap it with a plastic mallet, or other soft material, to be sure it stays in the valve.

4. Hex nuts (key 16, figure 19, 20, or 21) or cap screws (not shown) attach the bonnet (key 1, figure 18) to the valve
body (key 1, figure 19, 20, or 21). Loosen these nuts or cap screws 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. Work the
prying tool around the bonnet until the bonnet loosens. If no fluid leaks from the joint, remove the nuts or cap
screws completely and carefully lift the bonnet off the valve.
5. 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.
6. Remove the bonnet gasket (key 10, figure 19, 20, or 21) and cover the opening in the valve to protect the gasket
surface and prevent foreign material from getting into the valve body cavity.
7. Remove the packing flange nuts, packing flange, upper wiper, and packing follower (keys 5, 3, 12, and 13, figure
18). 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.
8. 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 by following the appropriate steps in the Trim
Maintenance procedure.
9. Remove the cover protecting the valve body cavity and install a new bonnet gasket (key 10, figure 19 through 21),
making sure the gasket seating surfaces are clean and smooth. Place the valve plug and stem into the valve body,
making sure it is properly centered on the seat ring. Then slide the bonnet over the stem and onto the stud bolts
(key 16, figure 19, 20, or 21) or onto the valve body cavity if cap screws (not shown) will be used instead.

TYPICAL (DOUBLE) ARRANGEMENT

Note
Proper performance of the bolting procedures in step 10 compresses the spiral wound gasket (key 12, figure 19 or 20) or load ring
(key 26, figure 21) enough to both load and seal the seat ring gasket (key 13, figure 19, 20, or 21). It also compresses the outer
edge of the bonnet gasket (key 10, figure 19 through 21) enough to seal the body-to-bonnet joint.
The bolting procedures in step 10 include--but are not limited to--ensuring that bolting threads are clean, and evenly tightening
the cap screws, or the nuts onto the studs, in a crisscross pattern. Tightening one cap screw or nut may loosen an adjacent cap
screw or nut. Repeat the crisscross tightening pattern several times until each cap screw or nut is tight and the body-to-bonnet
seal is made. When the operating temperature has been reached, perform the torquing procedure once again.

10. Install bolting, using accepted 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 3 as guidelines.
11. Install new packing and the metal packing box parts according to the appropriate arrangement in figure 3, 4, or 5.
Place a smooth-edged pipe over the valve stem and gently tap each soft packing part into the packing box.
12. Slide the packing follower, upper wiper, and packing flange (keys 13, 12, and 3, figure 18) into position. Lubricate
the packing flange studs (key 4, figure 18) and the faces of the packing flange nuts (key 5, figure 18). Install the
packing flange nuts.
13. For spring-loaded PTFE V-ring packing, tighten the packing flange nuts until the shoulder on the packing follower
(key 13, figure 18) contacts the bonnet.
For graphite packing, tighten the packing flange nuts to the maximum recommended torque shown in table 4. Then,
loosen the packing flange nuts, and retighten them to the recommended minimum torque shown in table 4.
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 4. Then, tighten the remaining flange nut until the
packing flange is level and at a 90-degree angle to the valve stem.
For ENVIRO-SEAL or HIGH-SEAL live-loaded packing, refer to the note at the beginning of Packing Maintenance.
14. 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
Observe the warning at the start of the Maintenance section.

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 19 for standard NPS 1 through 6
constructions, figure 20 for Whisper Trim III cage detail, figure 21 for the NPS 8 ED valve, and figures 22 and 23 for
WhisperFlo trim. Some valve plug constructions require three piston rings (key 6).

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

WARNING
Avoid personal injury or property damage from valve or packing leakage.
The graphite piston rings in an ED or EAD valve are brittle and in two pieces. Use care to avoid damage to the piston rings
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
critical for making a good packing seal. The inside surface of the cage or cage/baffle assembly (key 3), or cage retainer (key
31), is critical for smooth operation of the valve plug and for making a seal with the piston rings (key 6). The seating
surfaces of the valve plug (key 2) and seat ring (key 9) are critical for proper 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, 12, and 13, figure
18). 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 8 ED valve, or the cage adaptor (key 4) from any restricted-trim valve
through NPS 4, and wrap it for protection.
5. On an NPS 6 ED valve with a Whisper Trim III cage or WhisperFlo trim, 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 and WhisperFlo 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), and shim (key
51 for the ED valve, key 27 for the EAD valve). If the cage is stuck in the valve, use a rubber mallet to strike the
exposed portion of the cage at several points around its circumference.
7. Remove the seat ring or liner (key 9), seat ring gasket (key 13), and the seat ring adaptor (key 5) and adaptor gasket
(key 14) where used in a restricted-trim seat ring construction.
8. Inspect parts for wear or damage which would prevent proper operation of the valve. Replace or repair trim parts
according to the following procedure 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 lapping rotation will damage internal components of
the ENVIRO-SEAL Bellows Seal bonnet.

With metal-seat constructions, seating surfaces of the valve plug and seat ring or liner (keys 2 and 9, figure 19, 20, or
21) 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 compound to the bottom of the valve plug.
Assemble the valve to the extent that the cage and the cage retainer and bonnet spacer (if used) are in place and the
bonnet is bolted to the valve. A simple handle can be made from a piece of strap iron locked to the valve plug stem
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 as described in the Assembly portion of the Trim Maintenance procedure 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 19 for standard NPS 1 through 6
constructions, figure 20 for Whisper Trim III detail, figure 21 for the NPS 8 ED valve, and figures 22 and 23 for
WhisperFlo trim. Some valve plug constructions require three piston rings (key 6).

CAUTION
To avoid the piston ring (key 6) not sealing properly, be careful not to scratch the surfaces of the ring groove in the valve
plug or any of the surfaces of the replacement ring.

1. With the valve plug (key 2) removed according to the Disassembly portion of the Trim Maintenance procedure,
proceed as appropriate:
For the 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 directions, as shown in view
A of figure 19.
For the 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.

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.

Note
For plain bonnets and style 1 extension bonnets, the valve plug (key 2), valve stem (key 7), and pin (key 8) are available completely
assembled. Refer to the Key 2, 7, and 8 Valve Plug and Stem Assembly tables in the Parts List.

2. To replace the valve stem (key 7), drive out the pin (key 8). Unscrew the valve plug from the stem or adaptor.
3. To replace the adaptor (key 24, figure 18) 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 18). 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 18) from the valve stem assembly (key 20, figure 18).
4. Screw the new stem or adaptor into the valve plug. Tighten to the torque value given in table 5. Refer to table 5 to
select the proper drill size. Drill through the stem or adaptor, using the hole in the valve plug as a guide. Remove
any chips or burrs and drive in a new pin to lock the assembly.
5. For ENVIRO-SEAL bellows seal bonnets, grip the flats of the stem extending out of the top of the bellows shroud
with a soft-jaw chuck or other type of vise. Screw the valve plug/adaptor assembly onto the valve stem. Tighten as

12

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 or liner (key 9).
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. The level D3 cage/baffle assembly, however, must be installed with the hole pattern end next to the seat ring. If
a cage retainer (key 31) is to be used, place it on top of the cage.
4. Slide the valve plug (key 2) and stem assembly, or valve plug and ENVIRO-SEAL bellows seal assembly, into the cage
until the piston ring(s) is level with the top of the cage (key 3) or cage retainer (key 31).
5. Installing piston rings (key 6):
a. For valve plugs with a single piston ring: Make sure the piston ring is evenly engaged into the entrance chamfer
at the top of the cage or cage retainer ring. Carefully press the piston ring into the cage or cage retainer ring.
b. For valve plugs with multiple piston rings: As each piston ring is slid into the cage, make sure the ring is evenly
engaged in the entrance chamfer at the top of the cage or cage retainer. Also, make sure to offset the fracture in
the rings to minimize leakage. Carefully press each piston ring into the cage or cage retainer ring.
6. Place the gaskets (keys 12, 11 or 14 if used, and 10) and the shim (key 27 or 51) if used, on top of the cage or cage
retainer. If there is a cage adaptor (key 4) or a bonnet spacer (key 32), set it on the cage or cage retainer gaskets and
place another flat sheet gasket (key 10) on top of the adaptor or spacer. If there is only a cage retainer, place
another flat sheet gasket on the retainer.
7. With an NPS 8 ED valve, install the load ring (key 26).
8. Mount the bonnet on the valve and complete assembly according to steps 10 through 14 of the Replacing Packing
procedure. Be sure to observe the note prior to step 10.

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:

13

Instruction Manual

ED Valve

D100390X012

October 2014

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 plug seal. Also, lubricate the
outside diameter of the valve plug where the C-seal plug seal must be pressed into the proper sealing position
(figure 6).
2. Orient the C-seal plug seal for correct sealing action based on the process fluid flow direction through the valve.
D The open interior of the C-seal plug seal must face up in a valve with flow-up construction (figure 6).
D The open interior of the C-seal plug seal must face down in a valve with flow-down construction (figure 6).

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 Fisher spare part
or a tool could be manufactured following the dimensions given in figure 7.

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
reference surface of the valve plug (figure 8).
4. Apply a suitable high-temperature lubricant to the threads on the plug. Then, place the C-seal retainer onto the
plug and tighten the retainer using an appropriate tool such as a strap wrench.

5. Using an appropriate tool such as a center punch, stake the threads on top of the plug in one place (figure 9) to
secure the C-seal retainer.
6. Install the new plug/retainer assembly with C-seal plug seal on the new stem following the appropriate instructions
in the Trim Replacement section of this manual.
7. Install piston rings by following instructions in the Trim Replacement section of this manual.
8. Remove the existing valve actuator and bonnet following the appropriate instructions in the Replacing Packing
section of this manual.

CAUTION
Do not remove the existing valve stem from the valve plug 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.

9. Remove the existing valve stem and plug, cage, and seat ring from the valve body following the appropriate
instructions in the Trim Removal section of this manual.
10. Replace all gaskets according to appropriate instructions in the Trim Replacement section of this manual.
11. Install the new seat ring, cage, valve plug/retainer assembly, and stem into the valve body and completely
reassemble the valve package following the appropriate instructions in the Trim Replacement section of this
manual.

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 of
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.

3. Locate the staked thread on top of the valve plug (figure 9). 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 3 mm (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) from the groove(s) in the C-seal retainer.

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, the hole will be found in the upper groove.
6. Select an appropriate tool such as a punch and place the tip of the tool into the hole with the body of the tool held
tangent to the outside diameter of the retainer. Strike the tool with a hammer to rotate the retainer and free it from
the valve plug. Remove the retainer from the plug.
7. Use an appropriate tool such as a flat-blade screwdriver to pry the C-seal plug seal off the plug. Use caution to avoid
scratches or other damage to the sealing surfaces where the C-seal plug seal makes contact with the valve plug
(figure 10).
8. Inspect the lower seating surface where the valve plug contacts the seat ring for wear or damage which would
prevent proper operation of the valve. Also, inspect the upper seating surface inside the cage where the C-seal plug
seal contacts the cage, and inspect the sealing surface where the C-seal plug seal makes contact with the plug
(figure 10).
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 10) following
appropriate procedures in the Lapping Metal Seats section of this manual.

Remachining Metal Seats (C-seal Constructions)
See figure 11. A valve plug with a C-seal metal plug seal features two seating surfaces. One seating surface is found
where the valve plug contacts the seat ring. 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.

Trim Replacement (C-seal Constructions)
1. Apply a suitable high-temperature lubricant to the inside diameter of the C-seal plug seal. Also, lubricate the
outside diameter of the valve plug where the C-seal plug seal must be pressed into the proper sealing position
(figure 6).
2. Orient the C-seal plug seal for correct sealing action based on the process fluid flow direction through the valve.
D The open interior of the C-seal plug seal must face up in a valve with flow-up construction (figure 6).
D The open interior of the C-seal plug seal must face down in a valve with flow-down construction (figure 6).

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 Fisher spare part
or a tool could be manufactured following the dimensions given in figure 7.

3. Place the C-seal plug seal over the top of the valve plug and press it onto the plug using the installation tool.
Carefully press the C-seal plug seal onto the plug until the installation tool contacts the horizontal reference surface
of the valve plug (figure 8).

4. Apply a suitable high-temperature lubricant to the threads on the plug. Then, place the C-seal retainer onto the
plug and tighten the retainer using an appropriate tool such as a strap wrench.
5. Using an appropriate tool such as a center punch, stake the threads on top of the plug in one place (figure 9) to
secure the C-seal retainer.
6. Replace the piston ring(s) following instructions in the Trim Replacement section of this manual.
7. Return the seat ring, cage, plug/retainer assembly, and stem to the valve body and completely reassemble the valve
package following the appropriate instructions in the Trim Replacement section of this manual.

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.

ENVIRO-SEAL Bellows Seal Bonnet
Replacing a Plain or Extension Bonnet with an ENVIRO-SEAL Bellows Seal Bonnet
(Stem/Bellows Assembly)
1. Remove the actuator and bonnet according to steps 1 through 5 of the Replacing Packing procedure in the
Maintenance section.
2. Lift out the cage.
3. Remove and discard the existing bonnet gasket. Cover the valve body opening to protect sealing surfaces and to
prevent foreign material from entering the valve body cavity.

Note
The ENVIRO-SEAL stem/bellows assembly for easy-e valves is available only with a threaded and drilled plug/adaptor/stem
connection. The existing valve plug can be reused with the new stem/bellows assembly or a new plug can be installed.

4. Inspect the existing valve plug. If the plug is in good condition, it can be reused with the new ENVIRO-SEAL
stem/bellows assembly. To remove the existing valve plug from the stem, first, place the existing plug stem
assembly 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 or drill out the pin (key 8).
5. Then, reverse the plug stem assembly in the soft-jaw chuck or vise. Grip the valve stem in an appropriate place and
unscrew the existing plug from the valve stem.

CAUTION
When installing a valve plug on the ENVIRO-SEAL stem/bellows assembly, the valve stem must not be rotated. Damage to
the bellows may result.
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.
