A31D Valve

April 2014

Installation

Recommended or ”preferred” installation for the A31D valve is with the flow into the shaft side of the disk (retaining ring downstream from the high pressure side of the valve).

The standard soft seal and standard Phoenix III seal offer ANSI/FCI 70-2 Class VI, bidirectional shutoff. The Phoenix III seal for fire-tested applications must be installed in the preferred direction. The Novex seal is unidirectional and should be installed in the preferred direction. See table 3.

For assistance in selecting the appropriate combination of actuator action and open valve position, consult your Emerson Process Management sales office.

WARNING

To avoid personal injury or property damage resulting from the sudden release of pressure:

D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

D Do not install the valve assembly where service conditions could exceed the limits given in this manual or on the

nameplates.

D Use pressure-relieving devices as required by government or accepted industry codes and good engineering practices

to protect from over-pressurizing the system.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

D 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. Responsibility for the safety of process media and compatibility of valve materials rests solely with the purchaser and end-user. Since some body/trim material combinations are limited in their pressure drop and temperature range capabilities, do not apply any other conditions to the valve without first contacting your Emerson Process Management sales office.

1. Isolatethecontrolvalvefromthelinepressure,releasepressure from both sides of the valve body, and drain the

process media from both sides of the valve. If using a power actuator, shut off all pressure lines to the power actuator, release pressure from the actuator, and disconnect the pressure lines from the actuator. Use lock-out procedures to be sure that the above measures stay in effect while you are working on the equipment.

WARNING

See the WARNING at the beginningof the Maintenance section for more information before removing the valve from the pipeline.

2. Install a three-valve bypass around the control valve assembly if continuous operation is necessary during

inspection and maintenance of the valve.

3. Inspect the valve to be certain that it is free of foreign material.

A31D Valve

Instruction Manual

D500248X012

CAUTION

Damage to the disk will occur if any pipe flanges or piping connected to the valve interfere with the disk rotation path. If piping flange has a smaller inner diameter than specified for schedule 80 piping, measure carefully to be certain the disk rotates without interference before placing the valve into operation.

Be certain that adjacent pipelines are free of any foreign material, such as pipe scale or welding slag, that could damage the valve sealing surfaces.

Installing Double-Flange Valves

WARNING

The edges of a rotating valve disk have a shearing effect that may result in personal injury. To avoid personal injury, keep clear of the disk edges when rotating the disk.

CAUTION

To avoid damage to the valve disk during installation, the valve must be in the fully closed position. If the A31D valve is equipped with a fail-open actuator, remove the actuator before installing the valve/actuator assembly or cycle the valve into the fully closed position. Then, take appropriate steps to ensure that the actuator does not cause the valve to open during installation.

1. See table 2 for flange bolt specifications.

2. Properly orient the valve according to the specific application. For optimum performance, install the valve so that

the shaft will be on the high pressure side of the valve at shutoff.

3. Position the valv e between the flanges. Be sure to leave enough room for the flange gaskets. Install the lower flange

bolts.

4. Select the appropriate gaskets for the application. Flat sheet, spiral wound, or other gasket types, made to the

ASME B16.5 group standard or user's standard, can be used on the valve depending on the service conditions of the application. Install the gaskets and align the valve and the gaskets.

5. Install the remaining bolts.

6. Tighten the flange bolts in an alternating criss-cross fashion to a torque value of one-forth of the final bolting

torque. Repeat this procedure several times increasing the torque value each time by a forth of the final desired torque. When the final torque value has been applied, tighten each flange bolt again to allow for gasket compression.

WARNING

An A31D valve body is not grounded when installed in a pipeline. To avoid personal injury or property damage, always make sure that the valve body is grounded to the pipeline before putting the valve assembly into operation in a flammable or hazardous atmosphere. To provide shaft and disk-to-body grounding, attach a grounding strap to the shaft with a clamp and connect the other end of the grounding strap assembly to the valve body.

7. If necessary, attach a grounding strap from the valve body or pipeline to the valve shaft. For additional information

on grounding procedures, contact your Emerson Process Management sales office.

An A31D valve is normally shipped as part of an assembly with an actuator and other accessories such as a valve positioner. If the valve and actuator have been purchased separately or if the actuator has been removed for maintenance, properly mount the actuator and adjust valve/actuator travel and all travel stops before inserting the valve into the line.

CAUTION

Damage to the disk will occur if any pipe flanges or piping connected to the valve interfere with the disk rotation path. Be certain to align the valve accurately to avoid contact between the disk (key 2) and the flanges.

Adjusting the Actuator Travel Stops or Travel

Key number locations are shown in figure 9, 10, or 11, unless otherwise noted.

1. Refer to the actuator instruction manual to locate the actuator travel stop that controls the closed position of the valve disk (key 2). When adjusting the travel stop or travel, make sure that the disk is from 0.25 to 0.76 mm (0.010 to0.030inch)awayfromtheinternalstopinthevalvebody(seefigure5).Thisadjustmentisnecessarytobe certain that the actuator output torque is fully absorbed by the actuator travel stop or by the actuator. The internal travel stop in the valve body should not absorb any of the actuator torque.

CAUTION

When using an actuator, the actuator travel stop (or actuator travel, for actuators without adjustable stops) must be adjusted so the disk stop in the valve does not absorb the output of the actuator. Failure to limit the actuator travel as described in the Adjusting the Actuator Travel Stops or Travel steps can result in damage to the valve, shaft(s), or other valve components.

2. Before installing the valve/actuator assembly in the process line, cycle the valve several times to be sure the valve disk returns to the proper position.

Installing the Valve

The maximum allowable inlet pressures for A31D valves are consistent with the applicable ASME pressure/temperature ratings except where limited by the material capabilities.

A31D Valve

Instruction Manual

D500248X012

Refer to table 2 for the quantity and size of line bolting required to install the valve in the pipeline.

CAUTION

To avoid damage to the valve disk during installation, the valve must be in the fully closed position. If the A31D valve is equipped with a fail-open actuator, remove the actuator before installing the valve/actuator assembly or cycle the valve into the fully closed position. Then, take appropriate steps to be sure that the actuator does not cause the valve to open during installation.

2. Position the valv e between the flanges. Be sure to leave enough room for the flange gaskets. Install the lower flange bolts.

3. Select the appropriate gaskets for the application. Flat sheet, spiral wound, or other gasket types, made to the ASME B16.5 standard or user's standard, can be used on A31D valves depending on the service conditions of the application.

4. Install the remaining flange bolts.

5. Tighten the flange bolts in an alternating criss-cross fashion to a torque value of one-fourth of the final bolting torque. Repeat this procedure several times, increasing thetorquevalueeachtimebyafourthofthefinaldesired torque. After applying the final torque value, tighten each flange bolt again to allow for gasket compression.

Packing Adjustment and Shaft Bonding

WARNING

Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing might require some readjustmentto meet specific service conditions. Check with your process of safety engineer for any additional measures that must be taken to protect against process media.

1. For PTFE or graphite packing: Tighten standard packing follower nuts only enough to prevent shaft leakage. Excessive tightening of packing will accelerate wear and could produce higher rotating friction loads on the valve stem. If necessary, refer to the Packing Maintenance section.

CAUTION

For non-ENVIRO-SEAL packing: Tighten the packing follower nuts only enough to prevent shaft leakage. Excessive tightening will accelerate wear of the packing and could produce higher friction loads on the valve stem.

2. ENVIRO-SEAL Packing Systems: will not require this initial re-adjustment. Refer to the separate instruction manual, Fisher ENVIRO-SEAL Packing System for Rotary Valves (D101643X012), for repair and adjustment procedures.

3. For hazardous atmosphere or oxygen service valves, read the following Warning, and provide the bonding strap assembly mentioned below if the valve is used in an explosive atmosphere.

WARNING

The valve shaft is not necessarily grounded when installed in a pipeline unless the shaft is electrically bonded to the valve.

To avoid personal injury or property damage resulting from the effects of a static electricity discharge from valve components in a hazardous atmosphere or where the process fluid is combustible, electrically bond the drive shaft (key 3) to the valve accordingto the following step.

A31D Valve

April 2014

Note

Standard PTFE packing is composed of a partially conductive carbon-filled PTFE female adaptor with PTFE V-ring packing. Standard graphite packing is composed of all conductive graphite ribbon packing. Alternate shaft-to-valve body bonding is available for hazardous service areas where the standard packing is not sufficient to electrically bond the shaft to the valve (see the following step).

Instruction Manual

D500248X012

4. Attach the bonding strap assembly (key 131, figure 4) to the shaft with the clamp (key 130, figure 4).

5. Connect the other end of the bonding strap assembly to the valve flange cap screws.

6. For more information, refer to the Packing Maintenance section below.

Maintenance

Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions.

Key numbers in this procedure are shown in figure 9, 10, or 11 unless otherwise indicated.

WARNING

The valve closes with a shearing action. To avoid personal injury, keep hands, tools, and other objects away from the valve while its being stroked.

Avoid personal injury from sudden release of process pressure. 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 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. 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.

Removing and Replacing the Actuator

Refer to the appropriate actuator instruction manual for actuator removal and replacement procedures. The actuator stops or travel stops must limit the rotation of the valve shaft. See the CAUTION below.

CAUTION

When using an actuator, the actuator travel stop (or actuator travel stop, for actuators without adjustable stops) must be adjusted so the disk stop in the valve does not absorb the output of the actuator. Failure to limit the actuator travel can result in damage to the valve, shaft(s), or other valve components.

Packing Maintenance

TheA31Dvalveisdesignedsothepackingcanbereplacedwithoutremovingthevalvefromtheprocesspipeline.

CAUTION

Usually, packing leakage can be eliminated by merely tightening the hex nuts (key 15) located above the packing follower (key 12) while the valve is in the pipeline. However, if leakage continues, the packing must be replaced.

For PTFE ENVIRO-SEAL packing system, refer to instruction manual, Fisher ENVIRO-SEAL Packing System for Rotary Valves (D101643X012) (see figure 8).

CAUTION

Never use a wrench or pliers on the drive shaft (key 3). A damaged shaft could cut the packing and allow leakage.

1. Before loosening any parts on the valve, release the pressure from the pipeline. Then, remove the hex nuts (key 15) and lift off the packing follower (key 12).

2. Remove the hex jam nuts (key 17) and the anti-blowout flange (key 10). Remove the packing follower (key 12). Refer to figure 6 for details of the anti-blowout protection parts.

The packing is now accessible.

3. Use a packing extractor to remove packing. Insert the corkscrew-like end of the tool into the first piece of packing and pull firmly to remove the packing. Repeat this process until all packing parts have been removed.

CAUTION

Be careful when cleaning the packing box. Scratches to the drive shaft (key 3) or inside diameter of the packing bore might cause leakage.

4. Before installing new packing, clean the packing box.

5. Install new packing one ring at a time, using the packing follower as a driver. If using split-ring packing, stagger the splitsintheringstoavoidcreatingaleakpath.

6. Reinstall the packing parts. Refer to figure8forthesequenceofpackingparts.

Removing the Valve

1. 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. Vent the power actuator loading pressure.

2. 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 t he process media from either side of the valve.

A31D Valve

April 2014

Instruction Manual

D500248X012

CAUTION

Damage to the valve disk can occur if the disk is not closed when the valve is being removed from the pipeline. If necessary, stroke the actuator to place the disk in the closed position while removing the valve from the pipeline.

3. Loosen the flange bolting that holds the valve. Make sure the valve cannot slip or twist while loosening and removing the bolting.

4. Before removing the valve from the pipeline, make sure the valve disk is closed. Removing the valve with the disk open could cause damage to the disk, piping, or pipe flanges.

5. After removing the valve from the pipeline, move the valve to an appropriate work area. Always support the valve properly.

6. When valve maintenance is complete, refer to the Installation procedures in this manual.

Seal Maintenance

Note

For larger valves, it is possible to replace the seal (key 5) while the actuator is mounted to the valve and can be accomplished by cycling the valve to 90 degrees open.

Key numbers in this procedure are shown in figure 9, 10, or 11 unless otherwise indicated.

1. After removing the valve from the pipeline, remove the manual or power actuator. Manually rotate the drive shaft (key 3) counterclockwise until the disk has moved a full 180 degrees away from the closed position.

WARNING

Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve. Support large valves during maintenance.

2. Lay the valve flat on a work bench in a secure position with the retaining ring (key 18) and retaining ring screws (key

19) facing up. Properly secure the valve on a suitable worktable so it cannot slip, twist, or fall during maintenance. Remove all retaining ring screws.

3. Remove the retaining ring by placing a socket head cap screw from the retaining ring into each of the two retaining ring jacking screw holes. Slowly turn the screws until the retaining ring has been lifted from the valve body. Remove the retaining ring to expose the seal in the T-slot area of the valve body.

Note

The A31D is available with different seal designs and components. See figure 2 to identify the specific seal design.

4. Insert a regular screwdriver or other similar tool under the top edge of seal and gently pry the seal out of the T-slot area in the valve body. Take care not to damage the seal or T-slot area of the valve body. After the seal has been removed, clean the T-slot area, retaining ring and, if required, polish the disk (key 2) thoroughly.

4. Re-install the retaining ring and the socket head cap screws. Tighten the cap screws just enough to eliminate any movement of the retaining ring. Do not over-tighten the retaining ring screws. Using a blunt-end tool, carefully tuck the lip of the seal ring under the retaining ring.

5. When the seal is under the lip of the retaining ring, continue to tighten the cap screws according to standard procedures. Do not fully torque screws at this time. Final tightening of screws is accomplished in step 7 of this procedure.

6. Manually rotate the drive shaft clockwise 180 degrees to return the disk (key 2) to its closed position.

7. The final seating of the retaining ring cap screws can now be done. For the screw torque values, refer to table 5. The seal is now fully installed. Refer to the Installation procedures in this manual.

NOVEX, Phoen ix III and/or Phoenix III Fire-Tested Seals

Install the seal ring (key 5) in the valve body by first placing the wider outside diameter of the seal ring into the T-slot area of the valve body which is shown in figure 2.

The backup O-ring (key 6) for the Phoenix III seal will have to be installed after placement of the seal ring in the valve body using a blunt-end tool. Do not use the seal tool directly on the metal seat. Use tools on the O-ring only.

2. With the seal ring inserted all the way around the body T-slot now lay the O-ring into the opening between the valve body and the seal ring. Use the seal tool to apply pressure to the O-ring and carefully tuck the O-ring down into the T-slot between the valve body and the seal ring.

Note

On larger valves, it may be more efficient to have someone hold down the seal ring while you push the O-ring into the T-slot.

3. Once the seal ring and backup O-ring have been fully installed into the body T-slot, the retaining ring gasket can be installed. This gasket is a thin graphite material. Punch one initial screw hole through the gasket for alignment, being careful not to cause additional damage to the gasket.

CAUTION

The retaining ring gasket is a thin graphite material. When you punch one initial screw hole through the gasket for alignment, be careful not to cause additional damage to the gasket.

4. Install the retaining ring and align the screw holes in the retaining ring with the holes in the valve body. Install the first retaining ring screw through the punched hole in the ring gasket. Install the other ring screws by pushing the screws through the graphite gasket and threading them into the valve body.

5. Tighten the retaining ring socket head cap screws just enough to eliminate any movement of the retaining ring. Do not over-tighten the retaining ring screws.

WARNING

Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve. Support large valves during maintenance.

6. To complete this step, stand the valve up. Support the valve securely using methods appropriate for the valve size. Ifaviseorotherclampsarebeingused,besuretonotdamagetheflangegasketsealingareaofthevalvebody.

7. Manually rotate the drive shaft (key 3) to turn the disk clockwise to meet the seal.

8. Tap the disk with a rubber mallet to drive it against the internal travel stop. When the disk makes contact with the stop, manually rotate the disk counterclockwise back out of the seal to a 90-degree open position. Repeat steps 7 and 8 three times.

Note

When attaching the actuatorto the valve, make sure the valve disk is not in contact with the valve internal travel stop (see figure

5). The valve disk should be positioned from 0.25 to 0.76 mm (0.010 to 0.030 inch) away from the internal stop in the valve body (see figure 5).

9. Use an appropriate tool (such as a feeler gauge) to position the disk (key 2) from 0.25 to 0.76 mm (0.010 to 0.030 inch) away from the internal stop in the valve body.

This adjustment is necessary to be certain that the actuator output torque is fully absorbed by the actuator travel stop or by the actuator. The internal travel stop in the valve body should not absorb any of the actuator torque.

CAUTION

10. The final seating of the retaining ring screws can now be done. For the screw torque values, refer to table 5.

Anti-Blowout Protection, Packing, Valve Shaft(s), Disk, and Bearing Maintenance

Removal

Note

NPS 3 through 8 valves (CL150) and NPS 3 through 6 valves (CL300) have a bearing stop pressed into the bearing bore immediately after the packing box.

Do not attempt to remove the bearing stop which is found in the drive shaft bearing bore immediately after the packing box. The bearing stop is pressed into the bearing bore. If the bearing stop needs replacement, contact your Emerson Process Management sales office for more information.

Note

The A31D valve has a two-piece shaft. In these procedures, the drive shaft is key 3. The shaft opposite the drive shaft is called the follower shaft (key 4).

CAUTION

When using an actuator, the actuator travel stop (or actuator travel adjustment, for actuators without adjustable stops) must be adjusted so the disk stop in the valve does not absorb the output of the actuator. Failure to limit the actuator travel as described in the next step can result in damage to the valve, shaft(s), or other valve components.

CAUTION

When removing the actuator from the valve, do not use a hammer or similar tool to drive the lever off the valve shaft. Driving the lever or a ctuator off the valve shaft could damage the valve internal parts.

If necessary, use a wheel puller to remove the lever or actuator from the valve shaft. It is okay to tap the wheel puller screw lightly to loosen the lever or actuator, but hitting the screw with excessive force could also damage internal valve parts.

Key numbers in this procedure are shown in figure 9, 10, or 11 unless otherwise indicated.

1. Remove the valve from the pipeline. Remove the actuator from the valve.

WARNING

Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve. Support large valves during maintenance.

CAUTION

Never use a wrench, pliers, or similar tool to turn the drive shaft. A damaged shaft can cut the packing and allow leakage.

Note

It is not necessary to remove the retaining ring and valve seal when removing the shaft(s) and disk.

Instruction Manual

D500248X012

2. Properly secure the valve on a suitable worktable so it cannot slip, twist, or fall during maintenance.

3. Removing the Anti-Blowout Design:

a. For PTFE or Graphite Packing: Remove the hex nuts (key 15) and pull off the packing flange (key 11). Remove the

hex jam nuts (key 17) and the anti-blowout flange (key 10). Remove the packing follower (key 12). For NPS 3 through 12, remove the anti-blowout ring (key 16), see figure 6.

b. For ENVIRO-SEAL Packing System: Remove the hex nuts (key 101), the packing flange (key 102), jam nuts (key

17), anti-blowout flange (key 10), and the spring pack assembly (key 103). For NPS 3 through 12, remove the anti-blowout ring (key 16), see figures 6 and 8.

4. Remove the packing from around the drive shaft.

Note

Different valves require slightly different procedures because different valve sizes/ pressure classes have different methods of connecting the disk and shaft(s). To identify the proper procedures, refer to the list below.

D CL150, NPS 3 through 8: One-piece shaft with 1 taper key, (see figure 9).

D CL150, NPS 10 and 12: Two-piece shaft. 1 taper key in the drive shaft; 1 tangential pin in the follower shaft, (see figure 10).

D CL150, NPS 14 through 24: Two-piece shaft with 2 tangential pins in the drive shaft; 1 tangential pin in the follower shaft,

(see figure 11).

D CL300, NPS 3 through 6: One-piece shaft with 1 taper key, (see figure 9).

D CL300, NPS 8 and 10: Two-piece shaft. 1 taper key in the drive shaft; 1 tangential pin in the follower shaft, (see figure 10).

D CL300, NPS 12 through 24: Two-piece shaft with 2 tangential pins in the drive shaft; 1 in the follower shaft, (see figure 11).

5. Proceed as appropriate, using the following instructions.

For valves with taper key, locate the taper key (key 9, figure 7) which runs through the drive shaft boss on the back of the valve disk. Using a pin punch on the smaller end of the key, drive it out of the disk and shaft. Driving a taper key in the wrong direction will tighten it.

Note

Certain valve sizes may have a taper key that is arc spot welded in place. To remove the key, use a punch on the smaller end of the taperkeyanddriveitoutofthediskandshaft,breakingtheweld.

For valves with tangential pins, locate the tangential pins (key 25) in the drive shaft (key 3) and the tangential pin (key 25) in the follower shaft (key 4 ).

a. Use a threaded rod with an appropriate spacer and nut as an extractor tool to remove the tangential pins. If using

a threaded rod, choose a rod with threads that fit the inside thread of the pins. The rod should extend several inches above the disk when it is screwed into a pin.

Instruction Manual

D500248X012

A31D Valve

April 2014

b. After screwing the rod into the pin, slide the spacer over the rod and pin. Thread the nut onto the rod and tighten

it. As the nut is tightened, the nut will drive the spacer against the disk. The increasing force will draw the pin from the disk.

1. Valves with a two-piece shaft have a gasket retainer and gasket (keys 20 and 21) on the follower shaft side of the valve. Remove the hex head bolts and lockwashers (keys 23 and 22) from the gasket retainer and remove the gasket retainer and gasket to expose the end of the follower shaft.

2. Support the valve disk properly, and remove the follower shaft. Pull the follower shaft from the valve body. Use a shaft extractor screwed into the puller hole in the end of the follower shaft.

3. Support the valve disk properly, and remove the drive shaft. Pull out the drive shaft (key 3) by hand-pulling or by using a shaft extractor screwed into the end of the shaft.

CAUTION

To avoid damage to the disk, seal ring, and T-slot area, do not force the disk past the seal or T-slot area. Remove the disk from the opposite side of the valve body.

4. After removing the shaft(s), remove the disk and the thrust bearings. Do not force the disk past the seal ring or T-slot area.

5. Remove the journal bearings (key 7). Using a suitable punch or puller, drive or pull the journal bearing(s) into the valvebodyborefromthedriveshaftbearingbore.Donotattempttoremovethebearingstop(key8).Removethe journal bearing from the follower shaft bearing bore.

6. Inspect the valve body bore, bearings, bearing bores, and packing box for damage.

Installing a One-Piece Shaft

Unless otherwise indicated, key numbers and part names are listed in figure 7.

1. Secure the valve in an upright position. Allow for easy access to the valve body bore. Allow for easy access to the drive shaft bearing bore.

2. Inspect all parts removed from the valve for wear or damage. Replace any worn or damaged parts. Clean the valve body and all parts to be installed with an appropriate solvent or degreaser.

CAUTION

Premature valve failure and loss of process control may result if bearings are improperly installed or are damaged during installation.

3. Using caution to prevent damage to the bearing, insert one journal bearing (key 7) from the valve body bore into the drive shaft bearing bore until it hits the bearing stop (key 8). When properly installed, a portion of the journal bearing will extend into the valve body bore.

4. Insertonejournalbearingfromthevalvebodyboreintotheshaftbearingboreoppositethejournalbearing installed in step 3. When correctly installed, this journal bearing will be flush with the valve body bore.

5. Installthevalvediskbyplacingthediskintothevalvebodyboresothecurvedsideofthediskpassesthroughthe end of the valve body that does not contain the T-slot. Align the shaft bore in the disk with the bearing bores.
