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.

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 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.
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. 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
Process Management 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.
Valves with ENVIRO-SEAL live-loaded packing or
HIGH-SEAL Heavy-Duty live-loaded packing will not
require this initial re-adjustment. See the Fisherr
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

ES Valve
Instruction Manual

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, or
HIGH-SEAL Live-Loaded Packing
System, D101453X012, for packing
instructions. Figure 9 shows a typical
HIGH-SEAL Packing system. Figures
10, 11, and 12 show typical
ENVIRO-SEAL packing systems.
If the valve has an ENVIRO-SEAL
bellows seal bonnet installed, refer to
this manual. See the ENVIRO-SEAL
Bellows Seal and Bonnet section for
information on the bellows seal
bonnet.

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 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.
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).

ES Valve
Instruction Manual

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.
WARNING
To avoid personal injury due to leaking
fluid, avoid damaging gasket sealing
surfaces. The seating surface of the
valve plug (key 2) is critical for proper
shutoff. Protect these surfaces
accordingly.
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.
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

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. When
the operating temperature has been
reached, perform this torquing
procedure once again.

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 6. 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

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.

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.
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

ES Valve
Instruction Manual

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.
