Description
These single‐port valves have cage guiding, quick‐change trim, and unbalanced push‐down‐to‐close valve plug action.
Valve configurations are as follows:
ES—Globe style valve (figure 1) with metal‐to‐metal seating as standard for all general applications over a wide range
of pressure drops and temperatures, and metal‐to‐PTFE seating is optional for more stringent shutoff requirements.
EAS—Angle valve version of ES, used to facilitate piping or in applications where a self draining valve body is required.
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.

D100397X012
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. 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 sales
office.
Before installing the valve, inspect the valve and pipelines for any damage and any foreign material which may cause
product damage.
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 sales office.
4. Use accepted piping and welding practices when installing the valve in the line. Internal elastomeric parts may stay
in place during the welding procedure. 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. Shrunk‐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 sales office
for additional information.
5. With a leak‐off bonnet construction, remove the pipe plugs (keys 14 and 16, figure 8) 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.

Instruction Manual
D100397X012
Valves with ENVIRO‐SEAL live‐loaded packing or HIGH‐SEAL Heavy‐Duty live‐loaded packing will not require this initial
re‐adjustment. See the Fisher instruction manuals titled ENVIRO‐SEAL Packing System for Sliding‐Stem Valves or
Heavy‐Duty 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 Kits 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 replacement. All maintenance operations
may be performed with the valve in the line.
WARNING
Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before starting
disassembly:
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 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 compression.
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.
CAUTION
Follow instructions carefully to avoid damaging the product surfaces, which could result in damage to the product.
Note
Whenever a gasket seal is disturbed by removing or shifting gasketed parts, a new gasket should be installed upon reassembly.
This is necessary to ensure a good gasket seal since the used gasket may not seal properly.
Note
If the valve has ENVIRO‐SEAL or HIGH‐SEAL live‐loaded packing installed, refer to instruction manuals ENVIRO‐SEAL Packing
System for Sliding‐Stem Valves (D101642X012

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 8). Use a good quality silicon‐base lubricant.
Packing used in oxygen service or in processes with temperatures over 260_C (500_F) should not be lubricated. 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.

Instruction Manual
D100397X012
Packing Maintenance
Key numbers refer to figure 3 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 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 8)
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, it is possible that the valve stem is 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, it
is possible that the leakage is 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, and release pressure from the valve.
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 8) or the hex
nuts (key 26, figure 8).
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.
If the cage sticks to the bonnet, proceed carefully with bonnet removal.
Note
The following step also helps to provide additional assurance that the valve body fluid pressure has been relieved.
3. Hex nuts (key 5, figure 8) attach the bonnet to the valve. 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 body. Work the prying tool around the bonnet until the bonnet loosens.

4. Loosen the packing flange nuts (key 5, figure 8) so that the packing is not tight on the valve stem. Remove any
travel indicator parts from the valve stem threads.
CAUTION
Avoid damage to the seating surface caused by the valve plug and stem assembly dropping from the bonnet 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.
5. Completely remove the cap screws (not shown) or hex nuts (key 16; figure 13, 14, or 15) that bolt the bonnet and
valve together and carefully lift the bonnet off.
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.

February 2020
Instruction Manual
D100397X012
CAUTION
To prevent possible product damage, cover the opening in the valve in the following procedure to prevent foreign material
from getting into the valve body cavity.
7. Remove the bonnet gasket (key 10, figure 13 through 15) and cover the opening in the valve 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 8).
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 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.
10. Remove the covering protecting the valve body cavity and install a new bonnet gasket (key 10, figure 13 through
15), making sure the gasket seating surfaces are clean and smooth. Then slide the bonnet over the stem and onto
the stud bolts (key 15, figure 13, 14, or 15) or onto the valve body cavity if cap screws (not shown) will be used
instead.
Note
Proper performance of the bolting procedures in step 11 compresses the spiral wound gasket (key 12, figure 13 through 15) or
load ring (key 26, figure 14) enough to both load and seal the seat ring gasket (key 13, figure 13, 14, or 15). It also compresses the
outer edge of the bonnet gasket (key 10, figure 13 through 15) 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 cap screws, or the nuts onto the studs, in a crisscross pattern. Because of the boltup characteristics of spiral wound
gaskets, 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.
11. Install bolting, using proper bolting procedures during tightening so that the body‐to‐bonnet joint will withstand
test pressures and application service conditions. The bolt torques in table 3 may be used as guidelines.
12. Install new packing and the metal packing box parts according to the appropriate arrangement in figure 3, 5, or 7.
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 part into the packing box, being sure that air is not trapped
between adjacent soft parts.
13. Slide the packing follower, upper wiper, and packing flange (keys 13, 12, and 3, figure 8) into position. Lubricate the
packing flange studs (key 4, figure 8) and the faces of the packing flange nuts (key 5, figure 8). 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 8) contacts the bonnet.
For ENVIRO‐SEAL or HIGH‐SEAL live‐loaded packing, refer to the note at the beginning of the Maintenance section.
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.

WARNING
To avoid personal injury due to leaking fluid, avoid damaging gasket sealing surfaces. 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. The seating surfaces of the valve plug (key 2) and seat
ring (key 9) are critical for proper shutoff. Unless inspection reveals otherwise, assume all these parts are in good condition
and protect them accordingly.
2. Packing parts can be removed if desired. Replace these parts as described in the Replacing Packing procedure.
Remove the load ring (key 26) from an NPS 8 ES valve, or the cage adaptor (key 4) from any restricted trim valve,
and wrap it for protection.
3. Lift the valve plug and stem assembly out of the valve and set it on a protective surface. If the valve plug is to be
reused, protect the valve plug seating surface to prevent scratches. On an NPS 6 ES valve with Whisper Trim III cage
or WhisperFlo trim, also 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 trim cage retainer has two 3/8 inch‐16 UNC tappings in which screws or bolts can be
installed for lifting.
4. Remove the cage or cage/baffle assembly (key 3), the associated gaskets (keys 10, 11, and 12), and shim (key 51 for
the ES valve, key 27 for the EAS valve). If the cage is stuck in the valve body, use a rubber mallet to strike the
exposed portion of the cage at several points around its circumference.
5. Remove the seat ring or liner (key 9) or disk seat (key 22), 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. PTFE seat constructions use a
disk (key 23) sandwiched between the disk seat and disk retainer (key 21).
6. 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.

Instruction Manual
D100397X012
ES Valve

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. Apply the 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 body. 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.
CAUTION
To avoid weakening the stem or adaptor that may cause failure in service, 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), which will weaken the stem. However, a used valve plug may be reused
with a new stem or adaptor.
Valve Plug Maintenance
Except where indicated, key numbers are referenced in figure 13 for NPS 1/2 through 6 constructions, figure 14 for
NPS 8 ES valves, figure 15 for Whisper Trim III cage detail, and figure 16 for WhisperFlo trim.
1. Remove the valve plug (key 2) according to the disassembly portion of the trim maintenance procedure.
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 8) 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 or drill out the pin (key 36, figure 8). Reverse the plug stem assembly 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 8) from the valve stem assembly (key 20, figure 8).
4. Screw the stem or adaptor into the valve plug. Tighten to the torque value given in table 5. Refer to table 5 to select
the proper hole 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
necessary to align the pin hole in the stem with one of the holes in the adaptor. Secure the adaptor to the stem with
a new pin.
Assembly
Except where indicated, key numbers are referenced in figure 13 for standard NPS 1/2 through 6 constructions, figure
14 for NPS 8 ES valves, figure 15 for Whisper Trim III cage detail, and figure 16 for WhisperFlo trim.
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), or disk seat (key 22). With a PTFE seat construction,
install the disk and disk retainer (keys 21 and 23).
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.
5. Place the gaskets (key 10, or keys 11, 12 and 14, if used) and the shim (key 27 or key 51) 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.
6. With an NPS 8 ES valve, install the load ring (key 26).
CAUTION
To avoid damaging packing with the valve stem threads, use care when installing the bonnet if the packing was not
removed from the bonnet.
