Valve Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Personal injury or equipment damage caused by sudden release of pressure or bursting of pressure retaining parts might
result if service conditions exceed those for which the product was intended. To avoid 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
This valve is intended for a specific range of pressures, temperatures and other application specifications. Applying
different pressure and temperatures to the valve could result in parts damage, malfunction of the control valve or loss of

control of the process. Do not expose this product to service conditions or variables other than those for which the product was
intended. If you are not sure what these conditions are you should contact your Emerson Process Management sales office
for more complete specifications. Provide the product serial number (shown on the nameplate, figure 2) and all other
pertinent information.

ELECTRIC ACTUATOR

WITH SPRING INFORMATION

WARNING
If you move or work on an actuator installed on a valve with loading pressure applied, keep your hands and tools away from
the stem travel path to avoid personal injury. Be especially careful when removing the stem connector to release all loading
on the actuator stem whether it be from air pressure on the diaphragm or compression in the actuator springs. Likewise
take similar care when adjusting or removing any optional travel stop. Refer to the relevant actuator Maintenance
Instructions.
If hoisting the valve take care to prevent people from being injured in case the hoist or rigging slips. Be sure to use
adequately sized hoists and chains or slings to handle the valve.

1. Before installing the valve, inspect it to be certain that the valve body cavity is free of all foreign material. Clean out
all pipelines to remove scale, welding slag and other foreign material.
2. 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. Flow through the valve must be in the direction
indicated by the arrow cast on the valve.
3. Use accepted piping practices when installing the valve in the pipeline. Use a suitable gasket between the valve and
the pipeline flanges.

4. If continuous operation is required during inspection or maintenance, install isolating valves on either side of the
control valve with a bypass valve to control the flow while the control valve is receiving maintenance.

WARNING
Personal injury could result from packing leakage. Valve packing is tightened before shipment; however the packing might
require some readjustment to meet specific service conditions.

Maintenance
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.
D Use bypass valves or completely shut off the process to isolate the valve from the process pressure. Relieve the process
pressure from both sides of the valve.
D Depending on the actuator construction, it will be necessary to manage the pneumatic actuator loading pressure and
any actuator spring pre-compression. It is essential to refer to the relevant actuator instructions in this manual to
ensure safe removal of the actuator from the valve.
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.

Actuator Maintenance
For electric actuators, see the supplier's instruction manual.
The following sections provide procedures for actuator maintenance. Refer to figures 18, 19, 20, and 21.
The actuator soft parts may require periodic replacement. This includes the diaphragm (key 10), diaphragm O-ring
(key 109), actuator rod bushing (key 19), and the actuator rod seal (key 20).
If the actuator stroking direction (air-to-open or air-to-close) is unknown, refer to the nameplate on top of the actuator
casing and figure 2.

Instruction Manual

GX Valve and Actuator

D103175X012

There are several optional actuator constructions, depending on supply pressure. Refer to the nameplate on the top of
the actuator to determine the construction installed. Refer to figure 3 and table 2 for proper spring configuration.

Note
Older GX actuator nameplates do not contain spring configuration information. If you require replacement springs or wish to
switch to an optional actuator construction, consult your Emerson Process Management sales office.

Note
When the GX actuator is equipped with the integrated FIELDVUE DVC2000 digital valve controller (figure 1), additional
considerations may be required. Refer to the FIELDVUE DVC2000 Digital Valve Controller Mounting section of this manual for
additional instruction.

Actuator Disassembly (For Air-to-Open Constructions - see figures 18 or 19)
1. Connect a separate air supply to the lower diaphragm casing via the air supply connection on the yoke (as shown in
figure 18 or 19) and apply sufficient air pressure to raise the valve plug/stem off the seat to mid-travel.
2. Remove the stem connector nut half (key 23), stem connector bolt half (key 24), and travel indicator (key 26).
3. Push the valve plug/stem (key 3) down until it contacts the seat.
4. Loosen the locknut (key 28) and thread the stem adjustor nut (key 27) down until it clears the top of the valve
plug/stem (key 3).
5. Shut off the air pressure and disconnect the separate air supply to the lower diaphragm casing (as shown in figure
18 or 19).

WARNING
To avoid personal injury or property damage due to actuator springs (keys 12 and 82) being under compression, remove the
long cap screws (key 16) last.
The upper actuator casing may remain fixed to the diaphragm and lower casing during disassembly, even if the casing cap
screws have been loosened. If this happens, the actuator springs are still under compression. The upper casing could
suddenly come loose and jump, due to the compressed energy of the springs. If the upper casing is stuck to the diaphragm
and lower casing when you begin loosening the casing cap screws, pry the casings apart with a prying tool. Always ensure
that the springs are dispersing energy and the upper casing is moving against the long bolts during disassembly.

6. Remove the short actuator casing cap screws and hex nuts (keys 17 and 18) first. Once these have been removed
from the actuator assembly, carefully remove the long actuator cap screws and hex nuts (keys 16 and 18),
alternating between them to gradually release the spring energy (compression).
7. Remove the upper diaphragm casing (key 9) and the actuator springs (key 12 and/or 82).
8. Lift off the actuator stem/diaphragm assembly (includes keys 22, 11, 10, 14, 13, 109, and 15) and remove the cap
screw (key 14), actuator spacer (key 13), actuator rod (key 22), and washer (key 15).
9. Replace the diaphragm (key 10), diaphragm O-ring (key 109), actuator rod bushing (key 19), and actuator rod seal
(key 20), as needed.

For further detail on the operation and maintenance of the DVC2000, refer to the DVC2000 instruction manual.
The FIELDVUE DVC2000 digital valve controller mounts directly to an interface pad on the GX actuator yoke leg,
eliminating the need for mounting brackets (see figure 1). Internal passageways in the actuator route the pneumatic
output to the actuator casing, which eliminates the need for external air supply tubing in the air-to-open
(spring-to-close) constructions. (The GX will also accommodate other valve positioners, using the NAMUR mounting
pads on the side of the yoke legs.)

The DVC2000 features linkage-less position feedback when mounted to the GX control valve. There are no touching
parts between the controller and the valve stem, which simplifies controller installation. If maintenance is required,
the DVC2000 can be easily removed from the valve.
In the air-to-open (spring-to-close) configuration, the air signal to the actuator casing is supplied through the air
supply connection on the GX actuator yoke leg (see figure 18 or 19). In the air-to-close (spring-to-open) configuration,
the air signal is supplied to the actuator through the air supply connection on the top of the actuator casing (see figure
20 or 21).
For an air-to-open construction, a DVC2000 will mount to the actuator (figure 18 or 19). The air signal is transmitted
to the lower casing through the pneumatic passageway marked “air supply connection” in figure 18 or 19.
For an air-to-close construction, DN 15 through DN 100 (NPS 1/2 through 4) only: in the actuator design (figure 20 or
21), the pneumatic signal is connected directly to the air supply connection in the upper actuator casing. The yoke is
symmetrical and the air passageways serve as a vent, whereby the DVC2000 can be easily moved from one side of the
valve to the other without rotating the actuator.

DVC2000 Mounting Procedures
Steps A and B of the following instructions apply to the actuator construction shown in figures 18, 19, 20, and 21.

A. Mounting the DVC2000 to an air-to-open GX actuator (spring-to-close) (see figure 4 and figure 18 or 19):
1. Attach the magnetic feedback array (supplied with the DVC2000) to the valve stem connector using the alignment
template (supplied with the mounting kit) for accurate alignment.
2. Remove the plug (R1/8) from the back of the DVC2000 housing (Port B in figure 4). This pneumatic output port on
the DVC2000 lines up with the integral GX actuator air supply connection (see figure 18 or 19).
3. Install the plug (either G1/4 or 1/4 NPT, included in the mounting kit) to the external output pneumatic port (Port A
in figure 4).
4. Remove the digital valve controller's cover.
5. Using a 6mm hex wrench, attach the digital valve controller to the GX actuator mounting pad on the side that has
the open pneumatic port. Be sure to place the O-ring seal between the digital valve controller's pneumatic output
and the actuator mounting pad (Port B, as shown in figure 4). Pneumatic tubing is not required because the air
passages are internal to the actuator. Also, install the insulating gaskets around the mounting bolts.
6. Check for clearance between the magnet assembly and the DVC2000 feedback slot. The magnet assembly should
be positioned such that the index mark in the feedback slot of the DVC2000 housing is between the valid range on
the magnet assembly throughout the range of travel. (See figure 4).
B. For air-to-close GX actuator (spring-to-open) (see figure 4 and figure 20 or 21):
1. Attach the magnetic feedback array (supplied with the DVC2000) to the valve stem connector using the alignment
template (supplied with the mounting kit) for accurate alignment.
2. In the air-to-close configuration it is required that an R1/8 plug be installed into the integral mount pneumatic port
on the back of the DVC2000 housing (Port B of figure 4).
3. Remove the digital valve controller's cover.
4. Using a 6mm hex wrench, attach the digital valve controller to the GX actuator mounting pad.

Note
The O-ring seal and G1/4 or 1/4 NPT plugs (supplied in the mounting kit) are not used with this actuator construction.

5. Check for clearance between the magnet assembly and the DVC2000 feedback slot. The magnet assembly should
be positioned such that the index mark on the pole pieces (back of the controller housing) is between the marks on
the magnet assembly throughout the range of travel. (See figure 4.)
6. Install tubing between the external pneumatic output connection of the DVC2000 (Port A of figure 4) to the air
supply connection (see figure 20 or 21) on top of the actuator casing.
When changing actuator action:
When field converting a GX actuator from air-to-open to air-to-close closed (or vice-versa), you will need to change the
plugs for the pneumatic passages in the DVC2000 housing.
D To convert from air-to-close to air-to-open (spring-to-close), remove the R1/8 pneumatic plug on the back of the
DVC2000 housing and install an O-ring (Port B of figure 4). Plug the external pneumatic output with a 1/4 NPT or
G1/4 plug (depending on the housing version). (Port A of figure 4.)
D To convert from air-to-open to air-to-close (spring-to-open), remove the external pneumatic plug (1/4 NPT or G1/4
plug, depending on the housing version from Port A of figure 4). Install an R1/8 plug on the back of the DVC2000
housing (Port B of figure 4). Install tubing between the pneumatic output connection of the DVC2000
(Port A) to the air supply connection on top of the actuator casing (see figure 20 or 21).

Packing Adjustment
For spring-loaded single PTFE V-ring packing (figure 15) or for Graphite ULF packing (figure 16), the Belleville spring
pack (key 34) maintains a sealing force on the packing. If leakage is detected around the packing follower (key 29)
check to be sure that the packing follower (key 29) is tight. Using a wrench, tighten the packing follower (key 29) in
1/4 turn intervals until the leakage is stopped. If leakage cannot be stopped in this manner, proceed to the Replacing
Packing section in this manual.

Replacing Packing (Pneumatic Actuators)
This section provides instruction on replacing packing in standard bonnets, extension bonnets, and bellows extension
bonnets.
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. Shut off all pressure lines to the actuator and release all pressure from the
actuator. Use lock-out procedures to ensure that the above measures stay in effect while you work on the equipment.
1. For air-to-open constructions:
a. Connect a separate air supply to the lower diaphragm casing via the air supply connection on the yoke (as shown
in figure 18 or 19) and apply sufficient air pressure to raise the valve plug/stem off the seat to mid travel.
b. Remove the stem connector nut half (key 23), stem connector bolt half (key 24), and travel indicator (key 26).
c. Push the valve plug stem (key 3) down until it contacts the seat.
d. Loosen the locknut (key 28) and thread the stem adjustor nut (key 27) down until it clears the top of the valve
plug stem (key 3).
e. Shut off the air pressure and disconnect the separate air supply to the lower diaphragm casing (as shown in figure
18 or 19).
2. For air-to-close constructions, as shown in figure 20 or 21, remove the stem connector nut half (key 23), stem
connector bolt half (key 24), and travel indicator (key 26).

WARNING
To avoid personal injury or property damage by uncontrolled movement of the actuator yoke (key 8), loosen the body/yoke
nuts (figures 18, 19, 20, and 21, key 7) or bonnet/yoke nuts (figures 22 and 23, key 46) by following the instructions in the
next step. Do not remove a stuck actuator yoke 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 actuator yoke.

Note
The following step also provides additional assurance that the valve body fluid pressure has been relieved.

3. For standard bonnet constructions (figures 18, 19, 20, and 21), body nuts (key 7) attach the actuator yoke (key 8)
to the valve body (key 1). Loosen these nuts approximately 3mm (1/8 inch).
For extension and bellows bonnet constructions, bonnet nuts (key 46) attach the actuator yoke (key 8) to the
extension bonnet (key 39). Loosen these nuts approximately 3mm (1/8 inch).
4. Then loosen the valve-to-yoke gasketed joint by either rocking the actuator yoke or prying between the valve and
actuator yoke. Work the prying tool around the actuator yoke until it loosens.

the Warning at the beginning of the Maintenance section to ensure proper steps have been taken to isolate the valve and
relieve process pressure, thus avoiding property damage or personal injury.

5. If no fluid leaks from the joint, loosen the packing follower (key 29) two turns to relieve the packing compression
load.
6. For standard bonnet constructions (figures 18, 19, 20, and 21), remove the body nuts (key 7) completely.
For extension and bellows bonnet constructions (figures 22 and 23), remove the bonnet nuts (key 46) completely.

CAUTION
To avoid property damage, place the actuator yoke on a protective surface, as described in the following procedure.

7. Carefully lift off the actuator yoke and set it on a protective surface to prevent damage.
For standard bonnet constructions, if the bonnet (key 4) together with the valve stem plug assembly has a tendency
to lift with the actuator yoke, ensure it does not drop from the actuator.
For extension and bellows constructions, ensure the bonnet (key 4) does not lift with the actuator yoke.
For DN150 balanced constructions, if the bonnet, guide sleeve, or valve stem assembly have a tendency to lift with
the actuator yoke, ensure they do not drop from the actuator.

CAUTION
For extension and bellows bonnet constructions, lifting the bonnet with the actuator yoke may cause possible damage to
the valve plug and to the bellows.

8. Remove the stem adjustor nut (key 27) and locknut (key 28).
9. For standard bonnet constructions, remove the bonnet and the valve plug/stem assembly and set on a protective
surface.
For extension and bellows bonnet constructions, remove only the bonnet (key 4).

Valve Trim Maintenance
Key numbers in this section refer to figures 18, 19, 20, 21, 22, and 23.

Valve Trim Disassembly
1. Remove the actuator and bonnet assembly as described in the Replacing Packing section (steps 1 through 10).
D For standard bonnet constructions (figures 18, 19, 20, 21, and 25), proceed to the Seat Ring / Cage Removal
section.
D For extension bonnet constructions (figure 22), proceed to step 3.
D For bellows bonnet constructions (figure 23), proceed to step 2.
2. For bellows bonnet constructions (figure 23), use a bellows nut tool made according to the dimensions in figure 26
and table 13 to remove the bellows nut (key 51) as follows:
a. Insert the bellows nut tool into the extension bonnet (key 39). Be certain the tool lugs are engaged in the
corresponding recesses in the bellows nut.
b. Use a torque gun or driver having sufficient torque capabilities according to table 10. Connect the gun to a
socket that snugly fits the hex head on the bellows nut tool.
c. Insert the socket onto the hex head of the bellows nut tool.

WARNING
Be careful to hold the torque gun, attached socket, and tool at right angles to the bellows nut when applying torque. Tilting
the gun and socket while applying torque may cause the lugs on the bellows nut tool to suddenly disengage from the lugs
on the bellows nut thus causing possible damage to the bellows nut and possible personal injury.

d. Remove the bellows nut (key 51).
3. For both extension and bellows bonnet constructions: Body nuts (key 7) attach the extension bonnet (key 39) to the
valve body (key 1). Loosen these nuts approximately 3mm (1/8 inch). Then loosen the extension bonnet-to-body
gasketed joint by either rocking the extension bonnet or prying between the body and extension bonnet. Work the
prying tool around the extension bonnet until it loosens.
4. Remove the body nuts (key 7) completely and carefully lift the extension bonnet (key 39), and valve plug/stem
extension assembly (key 3, 40 and 48) or plug/bellows/stem extension assembly (key 3, 49 and 48) from the top of
the valve body.

insert may drop out during stem disassembly. If this is the case, ensure it is retained for reassembly of the valve stem to the stem
extension.

6. Remove the plug/stem assembly (key 3) and bellows/stem assembly (key 49) from the extension bonnet. Remove
the bellows gasket (key 50).
7. Proceed to the Seat Ring Removal section.

Seat Ring / Cage Removal
CAUTION
Use care to avoid damaging the gasket sealing surfaces.
The surface finish of the valve stem (key 3) is critical for making a good packing seal. The seating surfaces of the seat ring
(key 2), cage (key 99), and the valve plug (key 3) are critical for tight shutoff and should therefore also be treated with care
and properly protected.

1. Packing parts can be removed from the bonnet if desired. Replace these parts as described in the section on Packing
Maintenance.
2. Use a seat ring tool made according to the dimensions in figure 5 and table 12 to remove the seat ring (key 2) as
follows:
a. Insert the tool into the valve body. Be certain the tool lugs are engaged in the corresponding recesses in the seat
ring.
b. Use a torque gun or driver having sufficient torque capabilities according to table 8. Connect the gun to a socket
that snugly fits the hex head on the seat ring tool.
c. Insert the socket onto the hex head of the seat ring tool.

WARNING
Be careful to hold the torque gun, attached socket, and tool at right angles to the seat ring when applying torque. Tilting
the gun and socket while applying torque may cause the lugs on the seat ring tool to suddenly disengage from the lugs on
the seat ring thus causing possible damage to the seat ring and possible personal injury.

Assembly of Balanced Trim
(Available in DN 80, 100, and 150 [NPS 3, 4, and 6] only)
Refer to figure 10.

CAUTION
To protect the valve plug seal ring (key 37) and to ensure it seals 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 3) removed according to the Disassembly portion of the Valve Trim Maintenance
procedure, proceed as appropriate:
The seal ring (key 37) cannot be reused because it is a closed ring which must be pried and/or cut from the groove.
Once the seal ring is removed, the elastomeric backup ring (key 38), which is also a closed ring, can be pried from the
groove.
To install a new backup ring and seal ring onto the valve plug, apply a general purpose silicone-base lubricant to both
rings (keys 38 and 37). Place the backup ring over the valve plug (key 3) and into the groove. Place the seal ring over
the top edge of the valve plug (key 3) so that it enters the groove on one side of the valve plug. Slowly and gently
stretch the seal ring and work it over the top edge of the valve plug. The PTFE material in the seal ring must be
permitted time to cold-flow during the stretching procedure, so avoid jerking sharply on this ring. Stretching the seal
ring over the valve plug may make it seem unduly loose when in the groove, but it will contract to its original size after
insertion into the bonnet.
2. Install the seat ring, valve plug/stem, bonnet and actuator yoke into the valve body by completing the assembly
according to steps 1 to 3 of the section Assembly of Unbalanced Trim.

Repair Nameplate
If required by the end-user, an optional repair nameplate is available for recording changes made to the valve trim
during maintenance (see figure 29). This nameplate can be ordered as a spare part, and is easily mounted to the
actuator casing using a casing bolt. (Reference the Parts Ordering section of this manual.)
As shown in figure 29, the repair nameplate provides locations for maintenance personnel to record trim data, such as:

Handwheel Operation
CAUTION
This handwheel is designed only for use with size 225 and 750 actuators with 20 mm travel. To avoid equipment damage,
do not assemble this handwheel on size 750 actuators with 40 mm travel or size 1200 actuators.

Principle of Operation
The GX handwheel is designed to compress the actuator springs and override the actuator fail action. Turning the
handwheel drives the screw, nut, and levers. The levers push against the stem connector to transfer this motion.
Reversing the direction of the handwheel will move the nut and levers in the opposite direction. Once the levers are no
longer in contact with the stem connector, the locking screw should be used to secure the handwheel against
undesired movement. To prevent damage due to overtravel, the handwheel should not be turned more than 2 full
turns past the point at which the levers no longer contact the stem connector.

WARNING
To avoid personal injury or loss of process control due to equipment damage, ensure the levers are completely disengaged
and the locking screw is tight while the valve is in normal pneumatic operation.

GX Valve and Actuator

Instruction Manual

August 2011

D103175X012

During normal pneumatic operation when the handwheel is not needed, a locking screw (see figure 6) is provided on
the side of the handwheel housing to lock the handwheel levers out of the way.

WARNING
To avoid personal injury or equipment damage due to possible sudden shifting or falling of the valve assembly, do not lift
the valve assembly by the handwheel.

GX Handwheel Installation (for use with 20mm travel only)
1. Note the orientation of the levers to the stem connector for either the air-to-close, spring-to-open configuration or
for the air-to-open, spring-to-close configuration, as shown in figure 7.
2. Adjust the handwheel to allow positioning the levers above the stem connector before installation.
3. Install the handwheel to the GX mounting pad with four studs and nuts, as shown in figure 6. Torque to 24 NSm (18
lbfSft).
4. Apply lithium grease to the grease zerk and to the tip of the levers (where they contact the stem connector), as
shown in figure 7.

Travel Stop Operation
Principle of Operation
CAUTION
This travel stop is designed only for use with size 225 and 750 actuators with 20 mm travel. To avoid equipment damage,
do not assemble this travel stop on size 750 actuators with 40 mm travel or size 1200 actuators.

The GX travel stop is designed to mechanically limit and stop the valve at a preset position in an emergency or upon
loss of instrument air. This assembly is mounted on the yoke with four studs. The lever pushes against the stem
connector to stop the travel. Travel position can be adjusted by two adjustable cap screws on the lever, as shown in
figure 8. A cover plate assembly is available to prevent pinch point damage caused by the lever, as shown in figure 8.

WARNING
To avoid personal injury or equipment damage due to possible sudden shifting or falling of the valve assembly, do not lift
the valve assembly by the travel stop.
To avoid personal injury or loss of process control due to equipment damage, screw the adjustable cap screws to ensure the
lever is completely disengaged while the valve is in normal pneumatic operation.

Setting the Travel Stop Position
After sending the required position air signal to the actuator, screw the adjustable cap screws to assure the lever
contacts with the stem connector tightly, then tighten the back nut. Check the actual stem position when giving the
100% air signal.
Standard Accuracy for the travel stop position is +/- 10% for 20 mm travel. For added precision, use the following
procedure.
1. Send the desired position air signal to the actuator.
2. Set the travel stop, screw the adjustable cap screws to assure the lever contacts with the stem connector tightly,
then tighten the back nut.
3. Send a 100% air signal.
4. Measure the difference between the actual stem position and the desired position.
5. Send the air signal for the desired position minus the differential position measured in step 4.
6. Reset the travel stop by adjusting the two cap screws and then tighten the back nut.
