Valve Installation

WARNING

Always wear protective gloves,clothing, and eyewear whenperforming any installation operationsto avoid personal injury.

Personal injury or equipment damagecaused by sudden release of pressureor bursting of pressure retaining partsmight result if service conditionsexceed those for which the productwas intended. To avoid injury ordamage, provide a relief valve for overpressure protection as required bygovernment or accepted industrycodes and good engineering practices.

Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.

If installing into an existingapplication, also refer to the WARNINGat the beginning of the Maintenancesection in this instruction manual.

CAUTION

This valve is intended for a specificrange of pressures, temperatures andother application specifications.Applying different pressure andtemperatures to the valve could resultin parts damage, malfunction of thecontrol valve or loss of control of theprocess. Do not expose this product toservice conditions or variables otherthan those for which the product wasintended. If you are not sure whatthese conditions are you shouldcontact your Emerson ProcessManagement sales office for morecomplete specifications. Provide theproduct serial number (shown on thenameplate, figure 2) and all otherpertinent information.

WARNING

If you move or work on an actuatorinstalled on a valve with loadingpressure applied, keep your hands andtools away from the stem travel path toavoid personal injury. Be especially

careful when removing the stemconnector to release all loading on theactuator stem whether it be from airpressure on the diaphragm orcompression in the actuator springs.Likewise take similar care whenadjusting or removing any optionaltravel stop. Refer to the relevantactuator Maintenance Instructions.

If hoisting the valve take care toprevent people from being injured incase the hoist or rigging slips. Be sureto use adequately sized hoists andchains or slings to handle the valve.

1. Before installing the valve, inspect it to be certainthat the valve body cavity is free of all foreignmaterial. Clean out all pipelines to remove scale,welding slag and other foreign material.

2. The control valve assembly may be installed inany orientation unless limited by seismic criteria.However, the normal method is with the actuatorvertical above the valve. Flow through the valvemust be in the direction indicated by the arrow caston the valve.

3. Use accepted piping practices when installing thevalve in the pipeline. Use a suitable gasket betweenthe valve and the pipeline flanges.

4. If continuous operation is required duringinspection or maintenance, install isolating valves oneither side of the control valve with a bypass valve tocontrol the flow while the control valve is receivingmaintenance.

WARNING

Personal injury could result frompacking leakage. Valve packing istightened before shipment; howeverthe packing might require somereadjustment to meet specific serviceconditions.

Maintenance

WARNING

Avoid personal injury or propertydamage from sudden release ofprocess pressure or bursting of parts.Before performing any maintenanceoperations:

� Always wear protective gloves,clothing, and eyewear whenperforming any maintenanceoperations to avoid personal injury.

� Disconnect any operating linesproviding air pressure, electric poweror a control signal to the actuator. Besure the actuator cannot suddenlyopen or close the valve.

� Use bypass valves or completelyshut off the process to isolate thevalve from the process pressure.Relieve the process pressure fromboth sides of the valve.

� Depending on the actuatorconstruction, it will be necessary tomanage the pneumatic actuatorloading pressure and any actuatorspring pre-compression. It is essentialto refer to the relevant actuatorinstructions in this manual to ensuresafe removal of the actuator from thevalve.

� Use lock-out procedures to besure that the above measures stay ineffect while you work on theequipment.

� The valve packing box maycontain process fluids that arepressurized, even when the valve hasbeen removed from the pipeline.Process fluids may spray out underpressure when removing the packinghardware or packing rings, or whenloosening the packing box pipe plug.

� Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.

Note

Whenever a gasket seal is disturbedby removing or shifting gasketedparts, install a new gasket duringreassembly. This ensures a goodgasket seal because the used gasketmay not seal properly.

Actuator Maintenance

The following sections provide procedures foractuator maintenance. Refer to figures 15, 16, 17,and 18.

The actuator soft parts may require periodicreplacement. This includes the diaphragm (key 10),actuator rod bushing (key 19), and the actuator rodseal (key 20).

If the actuator stroking direction (air-to-open orair-to-close) is unknown, refer to the nameplate ontop of actuator casing and figure 2.

Note

When the GX actuator is equipped withthe integrated FIELDVUE DVC2000Series digital valve controller (figure1), additional considerations may berequired. Refer to the FIELDVUEDVC2000 Digital Valve ControllerMounting section of this manual foradditional instruction.

FIELDVUE� DVC2000 Digital ValveController Mounting

This section provides instruction on mounting theFIELDVUE DVC2000 Series digital valve controllerto the Design GX control valve. For further detail onthe operation and maintenance of the DVC2000positioner, refer to the DVC2000 instruction manual.

The FIELDVUE DVC2000 Series digital valvecontroller mounts directly to an interface pad on theGX actuator yoke leg, eliminating the need formounting brackets (see figure 1). Internalpassageways in the actuator route the pneumaticoutput to the actuator casing, which eliminates theneed for external air supply tubing in the air-to-open(spring-to-close) constructions. (The GX will alsoaccommodate other valve positioners, using theNAMUR mounting pads on the side of the yokelegs.)

FOR AIR-TO-OPEN, INSTALL THE O-RING BEFOREMOUNTING TO THE GX ACTUATOR

Figure 3. DVC2000 Digital Valve Controller Mounting Details

The DVC2000 features linkage-less positionfeedback when mounted to the GX control valve.There are no touching parts between the controllerand the valve stem, which simplifies controllerinstallation. If maintenance is required, the DVC2000can be easily removed from the valve.

In the air-to-open (spring-to-close) configuration, theair signal to the actuator casing is supplied throughthe air supply connection on the GX actuator yokeleg (see figure 15 or 16). In the air-to-close(spring-to-open) configuration, the air signal issupplied to the actuator through the air supplyconnection on the top of the actuator casing (seefigure 17 or 18).

For an air-to-open construction, a positioner willmount to the actuator (figure 15 or 16). The air signalis transmitted to the lower casing through thepneumatic passageway marked “air supplyconnection” in figure 15 or 16.

For an air-to-close construction, DN 15 throughDN 100 (0.5 through 4-inch) size only: in theactuator design (figure 17 or 18), the pneumaticsignal is connected directly to the air supplyconnection in the upper actuator casing. The yoke issymmetrical and the air passageways serve as avent, whereby the DVC2000 positioner can be easilymoved from one side of the valve to the otherwithout rotating the actuator.

DVC2000 Mounting ProceduresSteps A and B of the following instructions apply tothe actuator construction shown in figures 15, 16,17, and 18.

A. Mounting the DVC2000 to an air-to-open GXactuator (spring-to-close) (see figure 3 andfigure 15 or 16):

1. Attach the magnetic feedback array (suppliedwith the DVC2000) to the valve stem connectorusing the alignment template (supplied with themounting kit) for accurate alignment.

2. Remove the plug (R1/8) from the back of theDVC2000 housing (Port B in figure 3). Thispneumatic output port on the DVC2000 lines up withthe integral GX actuator air supply connection (seefigure 15 or 16).

3. Install the plug (either G1/4 or 1/4 inch NPT,included in the mounting kit) to the external outputpneumatic port (Port A in figure 3).

4. Remove the digital valve controller’s cover.

5. Using a 6mm hex wrench, attach the digital valvecontroller to the GX actuator mounting pad on theside that has the open pneumatic port. Be sure toplace the O-ring between the digital valvecontroller’s pneumatic output and the actuatormounting pad (Port B, as shown in figure 3).


9

Pneumatic tubing is not required because the airpassages are internal to the actuator.

6. Check for clearance between the magnetassembly and the DVC2000 feedback slot. Themagnet assembly should be positioned such that theindex mark in the feedback slot of the DVC2000housing is between the valid range on the magnetassembly throughout the range of travel. (See figure 3).

B. For air-to-close GX actuator (spring-to-open)(see figure 3 and figure 17 or 18):

1. Attach the magnetic feedback array (suppliedwith the DVC2000) to the valve stem connectorusing the alignment template (supplied with themounting kit) for accurate alignment.

2. In the air-to-close configuration it is required thatan R1/8 plug be installed into the integral mountpneumatic port on the back of the DVC2000 housing(Port B of figure 3).

3. Remove the digital valve controller’s cover.

4. Using a 6mm hex wrench, attach the digital valvecontroller to the GX actuator mounting pad.

Note

The O-ring and G1/4 or 1/4 inch NPTplugs (supplied in the mounting kit)are not used with this actuatorconstruction.

5. Check for clearance between the magnetassembly and the DVC2000 feedback slot. Themagnet assembly should be positioned such that theindex mark on the pole pieces (back of the controllerhousing) is between the marks on the magnetassembly throughout the range of travel. (See figure 3.)

6. Install tubing between the external pneumaticoutput connection of the DVC2000 (Port A of figure 3) to the air supply connection (see figure 17or 18) on top of the actuator casing.

When changing actuator action:

When field converting a GX actuator fromair-to-open to air-to-close closed (or vice-versa), youwill need to change the plugs for the pneumaticpassages in the DVC2000 housing.

� To convert from air-to-close to air-to-open(spring-to-close), remove the R1/8 pneumatic plugon the back of the DVC2000 housing and install anO-ring (Port B of figure 3). Plug the externalpneumatic output with a 1/4 inch NPT or G1/4 plug(depending on the housing version). (Port A of figure 3.)

� To convert from air-to-open to air-to-close(spring-to-open), remove the external pneumaticplug (1/4 inch NPT or G1/4 plug, depending on thehousing version from Port A of figure 3). Install anR1/8 plug on the back of the DVC2000 housing (PortB of figure 3). Install tubing between the pneumaticoutput connection of the DVC2000 (Port A) to the airsupply connection on top of the actuator casing (seefigure 17 or 18).

Packing MaintenanceKey numbers refer to figures 12, 15, 16, 17, 18, 19,and 20.

Packing AdjustmentFor spring-loaded single PTFE V-ring packing (figure 12) or for Graphite ULF packing (figure 13),the Belleville spring pack (key 34) maintains asealing force on the packing. If leakage is detectedaround the packing follower (key 29) check to besure that the packing follower (key 29) is tight. Usinga wrench, tighten the packing follower (key 29) in 1/4turn intervals until the leakage is stopped. If leakagecannot be stopped in this manner, proceed to theReplacing Packing section in this manual.

Replacing PackingThis section provides instruction on replacingpacking in standard bonnets, extension bonnets, andbellows extension bonnets.

Isolate the control valve from the line pressure,release pressure from both sides of the valve bodyand drain the process media from both sides of thevalve. Shut off all pressure lines to the actuator andrelease all pressure from the actuator. Use lock-outprocedures to ensure that the above measures stayin effect while you work on the equipment.

1. For air-to-open constructions:

a. Connect a separate air supply to the lowerdiaphragm casing via the air supply connectionon the yoke (as shown in figure 15 or 16) andapply sufficient air pressure to raise the valveplug/stem off the seat to mid travel.


Form 5770June 2006

b. Remove the stem connector nut half (key 23),stem connector bolt half (key 24), and travelindicator (key 26).

c. Push the valve plug stem (key 3) down until itcontacts the seat.

d. Loosen the locknut (key 28) and thread thestem adjustor nut (key 27) down until it clears thetop of the valve plug stem (key 3).

e. Shut off the air pressure and disconnect theseparate air supply to the lower diaphragmcasing (as shown in figure 15 or 16).

2. For air-to-close constructions, as shown infigure 17 or 18, remove the stem connector nut half(key 23), stem connector bolt half (key 24), andtravel indicator (key 26).

WARNING

To avoid personal injury or propertydamage by uncontrolled movement ofthe actuator yoke (key 8), loosen thebody/yoke nuts (figures 15, 16, 17, and18, key 7) or bonnet/yoke nuts (figures19 and 20, key 46) by following theinstructions in the next step. Do notremove a stuck actuator yoke bypulling on it with equipment that canstretch or store energy in any othermanner. The sudden release of storedenergy can cause uncontrolledmovement of the actuator yoke.

Note

The following step also providesadditional assurance that the valvebody fluid pressure has been relieved.

3. For standard bonnet constructions (figures15, 16, 17, and 18), body nuts (key 7) attach theactuator 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 nutsapproximately 3mm (1/8 inch).

4. Then loosen the valve-to-yoke gasketed joint byeither rocking the actuator yoke or prying betweenthe valve and actuator yoke. Work the prying toolaround the actuator yoke until it loosens.

WARNING

If there is evidence of process fluidunder pressure leaking from the joint,retighten the valve body/joint nuts andreturn to the Warning at the beginningof the Maintenance section to ensureproper steps have been taken toisolate the valve and relieve processpressure.

5. If no fluid leaks from the joint, loosen the packingfollower (key 29) two turns to relieve the packingcompression load.

6. For standard bonnet constructions (figures15, 16, 17, and 18), remove the body nuts (key 7)completely.For extension and bellows bonnet constructions(figures 19 and 20), remove the bonnet nuts (key 46) completely.

CAUTION

To avoid property damage, place theactuator yoke on a protective surface,as described in the followingprocedure.

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

CAUTION

For extension and bellows bonnetconstructions, lifting the bonnet with


11

the actuator yoke may cause possibledamage to the valve plug and to thebellows.

8. Remove the stem adjustor nut (key 27) andlocknut (key 28).

9. For standard bonnet constructions, removethe bonnet and the valve plug/stem assembly andset on a protective surface.For extension and bellows bonnet constructions,remove only the bonnet (key 4).For DN150 balanced constructions, remove theguide sleeve, bonnet, and valve plug stemassembly.

10. Remove the valve/yoke gasket (figures 15, 16, 17, and 18 key 5, figures 19 and 20key 47) and cover the opening of the valve to protectthe gasket surface and prevent foreign matter fromgetting into the valve cavity.

11. Remove the packing follower (key 29) from thebonnet (key 4).

12. Remove the Belleville spring pack (key 34) andpacking spacer (key 30) from the bonnet (key 4).Carefully push out the remaining packing box partsfrom the bonnet (key 4) using a rounded rod or othertool which will not scratch the packing box wall.Clean the packing box and the metal packing boxparts.

CAUTION

Inspect the valve stem, threads andpacking box surfaces for any sharpedges that might cut the packing.Scratches or burrs could causepacking box leakage or damage thenew packing.

13. Inspect the valve stem, threads and packing boxsurfaces for any sharp edges that might cut thepacking. Scratches or burrs could cause packing boxleakage or damage the new packing. If the surfacecondition cannot be improved by light sanding,replace the damaged parts.

14. Remove the covering protecting the valve cavityand install a new valve/yoke gasket (figures 15, 16, 17, and 18 key 5, figures 19 and 20key 47) making sure that the gasket seating surfacesare clean and smooth.For DN150 balanced constructions, two gasketsare required; one between the valve body and guide

sleeve, and the other between the guide sleeve andbonnet. Ensure the gasket seating surfaces areclean and smooth for both gaskets.

15. Carefully install the bonnet (key 4) onto thevalve stem.

16. Install the new packing and the metal packingbox parts according to figure 12 for PTFE packingand according to figure 13 for Graphite ULF packing.Place a smooth-edged pipe over the valve stem andgently tap each soft packing part into the packingbox. Apply anti-seize lubricant to the threads andinstall the packing follower (key 29).

17. Install the locknut (key 28) and stem adjustornut (key 27).For standard bonnet constructions, install thevalve plug/bonnet sub assembly into the valve body(key 1).

18. Mount the actuator onto the valve and install thebody nuts (figures 15, 16, 17, 18 key 7, figures 19and 20 key 46), but tighten them only finger-tight.

19. For air-to-open, connect a separate air supplyto the lower diaphragm casing air supply connection(as shown in figure 15 or 16) and apply sufficient airpressure to raise the actuator rod (key 22) to thetravel stop. Proceed to the next step.For air-to-close, proceed to the next step.

20. For standard bonnet constructions, tightenthe body nuts (key 7) evenly using a cross-tighteningprocedure. See table 3 for torque requirements.For extension and bellows bonnet constructions,tighten the bonnet nuts (key 46) evenly using across-tightening procedure. See table 4 for torquerequirements.

21. Tighten the packing follower (key 29) to thetorque specified in table 6.

Alternately, the packing follower can be tightened bythe following method:

a. Tighten the packing follower until the Bellevillesprings are compressed 100% (or completelyflat), as detected by a rapid increase in nuttorque.

b. For DN 15 through DN 100 (1/2 through4-inch), loosen the packing follower 60� ofrotation.For DN 150 (6-inch), loosen the packing follower180� of rotation.

CAUTION

To protect the valve plug seal ring (key37) and to ensure it seals properly, becareful not to scratch the surfaces of thering groove in the valve plug or any ofthe surfaces of the replacement ring.

1. With the valve plug (key 3) removed according tothe Disassembly portion of the Valve TrimMaintenance procedure, proceed as appropriate:

The seal ring (key 37) cannot be reused because itis a closed ring which must be pried and/or cut fromthe groove. Once the seal ring is removed, theelastomeric backup ring (key 38), which is also aclosed ring, can be pried from the groove.

To install a new backup ring and seal ring onto thevalve plug, apply a general purpose silicone-baselubricant to both rings (keys 38 and 37). Place thebackup ring over the valve plug (key 3) and into thegroove. Place the seal ring over the top edge of thevalve plug (key 3) so that it enters the groove on oneside of the valve plug. Slowly and gently stretch theseal ring and work it over the top edge of the valveplug. The PTFE material in the seal ring must bepermitted time to cold-flow during the stretchingprocedure, so avoid jerking sharply on this ring.Stretching the seal ring over the valve plug maymake it seem unduly loose when in the groove, but itwill contract to its original size after insertion into thebonnet.

2. Install the seat ring, valve plug/stem, bonnet andactuator yoke into the valve body by completing theassembly according to steps 1 to 3 of the sectionAssembly of Unbalanced Trim.

Repair NameplateIf required by the end-user, an optional repairnameplate is available for recording changes madeto the valve trim during maintenance (see figure 23).This nameplate can be ordered as a spare part, andis easily mounted to the actuator casing using acasing bolt. (Reference the Parts Ordering section ofthis manual.)

As shown in figure 23, the repair nameplate provideslocations for maintenance personnel to record trimdata, such as:

� Date of maintenance

� Trim material

� Port diameter

� Flow capacity (Cv / Kv)

� Flow characteristic

Bellows MaintenanceThis section provides instruction on the replacementof the bellows / stem assembly (see key 49 in figure 20).

1. Remove the actuator, bonnet assembly asdescribed in the Replacing Packing section (steps 1through 10).

2. Remove the plug/stem assemblies as describedin the Valve Trim Disassembly section (steps 2through 6).

3. To install the new bellows / stem assembly (key 49), perform the Valve Trim Assembly (step 3).

Figure 6. Design GX Handwheel Orientation and Grease Zerk Location

Handwheel Operation

Principle of OperationThe Design GX handwheel is designed to compressthe actuator springs and override the actuator failaction. Turning the handwheel drives the screw, nut,

and levers. The levers push against the stemconnector to transfer this motion. Reversing thedirection of the handwheel will move the nut andlevers in the opposite direction. Once the levers areno longer in contact with the stem connector, thelocking screw should be used to secure thehandwheel against undesired movement. To prevent


Form 5770June 2006

18

damage due to overtravel, the handwheel should notbe turned more than 2 full turns past the point atwhich the levers no longer contact the stemconnector.

WARNING

To avoid personal injury or loss ofprocess control due to equipmentdamage, ensure the levers arecompletely disengaged and thelocking screw is tight while the valve isin normal pneumatic operation.

During normal pneumatic operation when thehandwheel is not needed, a locking screw (seefigure 5) is provided on the side of the handwheelhousing to lock the handwheel levers out of the way.

WARNING

To avoid personal injury or equipmentdamage due to possible suddenshifting or falling of the valveassembly, do not lift the valveassembly by the handwheel.

Design GX Handwheel Installation1. Note the orientation of the levers to the stemconnector for either the air-to-close, spring-to-openconfiguration or for the air-to-open, spring-to-closeconfiguration, as shown in figure 6.

2. Adjust the handwheel to allow positioning thelevers above the stem connector before installation.

3. Install the handwheel to the GX mounting padwith four studs and nuts, as shown in figure 5.Torque to 24 N�m (18 lbf�ft).

4. Apply lithium grease to the grease zerk and to thetip of the levers (where they contact the stemconnector), as shown in figure 6.
