Introduction
Scope of Manual
This instruction manual includes installation, maintenance, and parts information for NPS 1 through 4 EDR and ETR
valves (see figure 1). The valves are available in CL150 through 600 ratings.
The valves are also available with full‐size and restricted‐trim designs. Refer to separate manuals for instructions
covering the actuator and accessories.
Do not install, operate, or maintain an EDR or ETR valve without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to
carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you
have any questions about these instructions, contact your Emerson Process Management sales office before
proceeding.

Description
The EDR and ETR are single‐port, globe‐style valves that feature cage guiding, a balanced plug design, and
push‐down‐to‐open valve plug action. The valve constructions are available with metal‐to‐metal or
metal‐to‐composition seats. These constructions permit access to the internal trim parts through the bottom flange
without removing the actuator from the valve.

Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given on the valve and actuator nameplates. Use
pressure‐relieving devices as required by accepted industry, local, state, or Federal codes, and good engineering practices.
Check with your process or safety engineer for any other hazards that may be present from exposure to 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
The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop,
and controlled fluid conditions. Because some body/trim material combinations are limited in their pressure drop and
temperature range capabilities, do not exceed these conditions without first contacting your Emerson Process
Management sales office.
Inspect the valve and pipelines to ensure they are not damaged, are clean, and free of foreign material.

EDR and ETR Valves
April 2011

Instruction Manual
D100391X012

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 (see figure 2) on the side of the valve.
3. The control valve assembly can be installed in any orientation unless limited by seismic criteria. However, the
normal method is with the actuator vertical above the valve body (see figure 2). 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. If a post‐weld heat treatment
process is to be applied to the valve end connections, and the valve has composition or elastomer trim parts,
remove the trim to avoid damage to the soft parts.

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. Shrunk‐fit pieces and threaded connections may 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. 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 and also see figure 2.

WARNING
Personal injury could result from packing leakage. Valve packing was tightened prior to shipment; however some
readjustment will be required to meet specific service conditions.

Maintenance
WARNING
Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:
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.
D Use 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.
D Vent the power 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.

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 trim maintenance,
packing maintenance, and packing lubrication. All maintenance operations may be performed with the valve installed
in the pipeline.

Note
If the valve has ENVIRO‐SEALt live‐loaded packing installed (figure 8, 9, or 10), see the Fisher instruction manual entitled
ENVIRO‐SEAL Packing System for Sliding‐Stem Valves for packing instructions.

Trim Maintenance
Disassembly
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.

Key number locations are shown in figure 11 or 12 unless otherwise indicated.

CAUTION
Take care when removing the bottom flange (key 31) in the following procedure, to prevent possible product damage from
parts unexpectedly falling out of the valve body.

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, 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. When removing the bottom flange (key 31), be careful that the cage and
other parts are not damaged by unexpectedly falling out of the valve body. Remove the nuts (key 16) or cap screws
from the bottom flange.
2. Removing the valve plug from the valve body, the valve plug can be removed independently of the valve stem by
removing the cotter pin and castle nut (keys 30 and 8). Then, slide the valve plug out of the cage (see figure 3).
D Disconnect the stem connector, and loosen the packing flange nuts (see figure 2).
D Move the valve stem away from the actuator stem allowing room to remove the indicator disk and stem locknuts.
Remove the parts indicated.
D Remove the valve plug by pulling the valve plug/stem assembly through the packing and out of the bottom of the
bonnet.
D If the valve plug is to be re‐used but the stem needs to be replaced, drive the pin (key 8) out of the plug/stem
assembly and unscrew the valve stem.

CAUTION
Take care during disassembly in the following procedure, to prevent possible damage to sealing surfaces.

3. Remove the seat ring (key 9), gaskets (keys 10, 11, 12, and 13), and any remaining parts if they did not come out
with the valve plug. If the seat ring (key 9) is stuck in the valve body, strike the outside of the valve body at the seat
ring line with a rubber hammer while pulling down on the seat ring. Carefully remove the seat ring without
damaging sealing surfaces.
If necessary, machine or grind metal seats before installing the piston ring/seal ring or packing, or refer to the Lapping
Metal Seats procedure in this section.

Lapping Metal Seats
A certain amount of leakage should be expected with metal‐to‐metal seating in any valve body. If the leakage
becomes excessive, however, the condition of the seating surfaces of the valve plug and seat ring can be improved by
lapping. (Deep nicks should be machined out rather than ground out.) Use a good quality lapping compound of a
mixture of 280 to 600‐grit.
Assemble the valve to the extent that the seat ring (key 9), cage (key 3), cage adaptor (key 4, if used), and bonnet are
in place. Also, remove the piston ring or seal ring from the valve plug (if used).
1. Insert the valve stem (key 7) into the bonnet and thread the plug (key 2) onto the end of the stem. Make a simple
handle from a piece of strap iron; lock it to the valve with the stem locknuts.

2. Apply the lapping compound to the seating surfaces. Rotate the handle alternately in each direction to lap the
seats. After lapping the seats, remove the valve plug and stem, then clean all parts. Repeat the lapping procedure if
necessary.

Trim Assembly
Carefully clean all gasket surfaces. Use new gaskets during reassembly of the valve.

Replacing the Seal or Piston Ring
CAUTION
Be careful not to scratch the surface of the ring groove in the valve plug (key 2), or the new ring may not seal properly.

D For EDR, if the piston ring (key 6) is visibly damaged, remove the ring and replace it with a new part. Refer to the
Parts List at the end of this manual for a replacement part.
D For ETR, if the seal ring and backup ring (keys 24 and 25) are visibly damaged, remove the rings by prying or cutting
them from the groove. Be careful not to scratch valve plug surfaces. Refer to the Parts List at the end of this manual
for replacement parts.

Assembling the Valve Plug and Stem
1. For EDR and ETR, perform the following steps:
D Insert the stem (key 7) into the plug (key 2, figure 3) and thread the castle nut (key 8) onto the end of the stem and
hand tighten.

CAUTION
To prevent possible product damage, take care that the stem and plug are not damaged during the following tightening
procedure.

D When tightening the castle nut with a wrench, line up the hole in the end of the stem with a slot in the castle nut.
Ensure that the stem and plug are not damaged during the tightening procedure.
D Insert the cotter pin (key 30) and lock it in place.

Instruction Manual
D100391X012

Installing the Piston Rings or Backup Ring/Seal Rings
1. For EDR: When using a carbon‐filled PTFE piston ring, spread the ring apart slightly at the split, start one end of the
split into the groove in the valve plug. Work the ring around the valve plug inserting the ring into the groove in the
valve plug.
The replacement graphite piston rings will arrive in one piece. Use a vise with smooth or tapered jaws to break the
replacement piston ring into two halves. Place the new ring in the vise so that the jaws compress the ring into an oval.
Compress the ring slowly until the ring 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. The piston ring can also be fractured by scoring
and snapping over a hard surface such as a table edge. Sawing or cutting the ring is not recommended.
2. For ETR: Apply a lubricant to both backup and seal rings (keys 25 and 24). Place the backup ring over the stem (key
7) and into the groove in the valve plug (key 3). Slowly and gently stretch the seal ring over the valve plug and work
it into the groove. Stretching the ring over the valve plug can cause it to appear too large for the groove, but it will
contract to its original size when inserted into the cage.

CAUTION
When installing the EDR or ETR valve plug into the cage, make sure the piston or seal ring is evenly engaged in the entrance
chamfer of the cage to avoid damage to the ring.

Note
Use the preceding procedures to assemble the valve plug and stem before installing the parts into the valve body. Insert the valve
plug into the cage (figure 3), then stack the parts as recommended in steps below.

Installing the Parts into the Valve Body
1. Stack the valve trim parts using figures 11 and 12 to determine the sequence of parts.
2. Lubricate the stud bolts (key 15) before installing the valve trim into the valve body. (Note: For ease of installing
trim parts, remove all packing parts from the packing box before installing the trim parts.)
3. When inserting the stack of trim parts into the valve body, carefully align the parts in the recess of the valve body.
4. Slide the bottom flange onto the stud bolts (key 15). Secure the bottom flange (key 31) in place on the valve body
with the hex nuts (key 16). Tighten the hex nuts to the torque value shown in table 3.
5. Torque the nuts in a criss‐cross pattern. Repeat the pattern until all nuts are torqued to the value indicated in table
3.
6. Refer to the Packing Maintenance procedures below.

Packing Maintenance
This procedure covers PTFE V‐ring, graphite ribbon/filament, and PTFE composition packing rings. Key numbers refer
to figure 5 for PTFE V‐ring packing and PTFE/composition packing, unless otherwise indicated.

Note
If the valve has ENVIRO‐SEAL live‐loaded packing installed (figure 8, 9, or 10), see the Fisher instruction manual entitled
ENVIRO‐SEAL Packing System for Sliding‐Stem Valves for packing instructions.

Instruction Manual

EDR and ETR Valves

D100391X012

April 2011

For all except spring‐loaded packing, if the packing is relatively new and tight on the stem, and if tightening the
packing flange nuts does not stop the leakage, it is possible that the valve stem is worn or nicked so that a seal cannot
be made. If the leakage comes from the outside diameter of the packing follower, it is possible that the leakage is
caused by nicks or scratches around the inside of the packing box wall.
For spring‐loaded single PTFE V‐ring packing, the spring (key 8) maintains a sealing force on the packing. If leakage is
noted around the packing follower (key 13), 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 4) until the shoulder
is against the bonnet. If leakage cannot be stopped in this manner, proceed to the Removing Packing and Installing
Packing procedures below.

Removing Packing
WARNING
Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

The packing may have been removed in earlier steps, or during trim maintenance procedures. Use the following steps,
when necessary, to remove packing and associated assemblies.
Key number locations for packing parts are shown in figures 5 and 6. For valve parts and the live loaded packing
system, refer to figures 8 through 10 (in the Parts List section), for key number locations.
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. Exhaust all actuator pressure, disconnect the operating lines from the actuator, and disconnect any leakoff piping
from the actuator. Relieve any actuator precompression from the stem connector. (If necessary, refer to the
appropriate actuator instruction manual for warnings, cautions, and disassembly procedures.)
3. When removing the bottom flange (key 31), be careful that the cage and other parts are not damaged by
unexpectedly falling out of the valve body. Remove the nuts (key 16) or cap screws from the bottom flange.
4. To remove the packing for maintenance, disconnect the stem connector (see figure 2). Remove the yoke locknut,
and lift the actuator off the valve.
5. Remove the packing flange nuts (key 5, figure 4), packing flange (key 15), upper wiper (key 12), and packing
follower (key 13). If maintaining the packing while the valve stem is in place, ensure that the valve stem surface is
not scratched or marred while working with the packing.

REFER TO FIGURE 5 OR 6 FOR PACKING ARRANGEMENTS.

CAUTION
To prevent possible product damage, avoid scratching the packing box walls when removing old packing parts. Also
inspect valve stem threads and packing box surfaces for sharp edges which may damage packing.

6. Avoid scratching the packing box walls when removing the old packing parts. Clean the packing box (see figure 4),
and clean, inspect, or replace metal packing parts. Generally, the metal packing parts are not part of the packing
kits listed in the Parts List section, and they must be ordered individually.
7. Inspect the valve stem threads and packing box surfaces for any sharp edges which might cut the packing.
Scratches or burrs on the stem surfaces can cause packing box leakage or damage to 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.

Note
If the control valve assembly was purchased for an application where the service temperatures are under 232_C (450_F), the
bonnet may be unscrewed from the valve body. Where temperatures are greater than 232_C (450_F), the bonnet is seal welded to
the valve body.

CAUTION
To prevent possible product damage, set the bonnet on a protective surface in the following procedure.

8. If necessary, remove the bonnet assembly from the valve by unscrewing it. Some applications require seal welding
the bonnet to the valve body, and the bonnet should not be removed. Set the bonnet on a protective surface to
prevent damage to the bonnet gasket surface.

Installing Packing
If the trim is removed, refer to Trim Maintenance procedures, and install the trim (including the valve stem) before
installing the packing. If necessary, use the Lapping Metal Seats procedures before installing packing. Key number
locations are shown in figure 5 or 6 unless otherwise indicated.

CAUTION
To prevent possible product damage, take care when installing the bonnet over the valve stem in the following procedure.

1. If the bonnet has been removed from the valve body, install the replacement bonnet (see figure 4). Carefully slide
the bonnet over the valve stem without damaging the stem surfaces.
2. Refer to figure 5 or 6 for the sequence of parts to make up the appropriate packing set for your application. Arrange
the packing parts in sequence before installing them into the packing box.
3. For split‐ring packing, alternate the positions of the splits to avoid creating a leak path. Place a smooth‐edged pipe
over the valve stem and gently tap each soft packing ring into the packing box. Be sure that air is not trapped
between adjacent soft parts.
4. Install the packing follower (key 13), packing flange (key 3), and upper wiper (key 12, if required). Install the
packing flange nuts (key 5).
5. Refer to actuator installation procedures in the actuator instruction manual, and the installation procedures in the
manual when mounting and connecting the actuator to the valve. If lubrication is required, refer to the Packing
Lubrication section below.
6. For spring‐loaded PTFE V‐ring packing, tighten the packing flange nuts until the shoulder on the packing follower
(key 13, figure 4) 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 nuts until the
packing flange is level and at a 90‐degree angle to the valve stem.

Packing 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).

Instruction Manual

EDR and ETR Valves
April 2011

D100391X012

Packing used in oxygen service or in processes with temperatures over 260_C (500_F) should not be lubricated. If a
lubricator or lubricator/isolating valve (see figure 7) is required for the packing, install the lubricator or
lubricator/isolating valve into the threaded hole in the side of the bonnet (see figure 7). Use a good quality silicon‐base
lubricant.
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 the isolating valve must first be opened and then closed after
lubrication is completed.

Parts Ordering
Each body‐bonnet assembly is assigned a serial number which can be found on the valve body. This same number also
appears on the actuator nameplate when the valve is shipped from the factory as part of a control valve assembly.
Refer to the serial number when contacting your Emerson Process Management sales office for technical assistance.
When ordering replacement parts, refer to the serial number and to the eleven‐character part number for each part
required from the following parts kit or parts list information.

WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Process Management should not,
under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.

Note
Neither Emerson, Emerson Process Management, nor any of their affiliated entities assumes responsibility for the selection, use, or
maintenance of any product. Responsibility for the selection, use, and maintenance of any product remains with the purchaser and
end user.
