Installation

WARNING

Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury.

To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve assembly where service conditions could exceed the limits given on the valve and actuator nameplates. Use pressure-relieving devices as required by accepted industry, local, state, or federal 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.

1. If the valve will be placed in storage prior to installation, protect the flanges and keep the inside of the valve dry and clear of foreign material.

2. Install a three-valve bypass around the control valve assembly if continuous operation will be necessary during inspection and maintenance of the valve.

3. Inspect the valve body for damage and be certain that the valve body cavity is free of foreign material.

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

5. A Design V250 valve is normally shipped as part of a control valve assembly, with a power or manual handwheel actuator mounted on the valve. If the valve and actuator have been purchased separately or if the actuator has been removed for maintenance, mount the actuator according to the actuator mounting procedure and adjust actuator travel before inserting the valve into the pipeline. This allows necessary measurements to be made during the actuator adjustment process.

The actuator can be either right-or left-hand mounted, as viewed from the valve body inlet, in any

of the positions shown in figure 10. Refer to the Actuator Mounting procedure in this manual and to the actuator instruction manual for mounting and adjusting instructions before proceeding.

6. Before installing the valve, make sure the flow through the valve matches the flow direction arrow on the valve. Failure to do so can damage the seal in a valve with a single seal construction.

D For bidirectional flow, install the valve so the highest pressure flow matches the flow direction arrow on the valve.

D Install the valve in a horizontal pipeline

with the

shaft positioned horizontally

and the ball closing in

the downward direction.

Note

Do not allow the valve to be installed in the pipeline with the drive shaft in the vertical position because of excessive wear to component valve parts.

CAUTION

To avoid damage to the ball sealing surface, rotate the ball to the fully open position before installing the valve between the pipeline flanges.

7. With the ball in the fully open position, install line flange gaskets and insert the valve between the pipeline flanges. Use standard composition gaskets, or other flat sheet gaskets compatible with the flow media, between the valve and the pipeline flanges. Spiral wound gaskets without compression controlling centering rings are not recommended.

CAUTION

Uneven tightening of line bolts may cause uneven wear of the ball surface, leakage downstream or to atmosphere, or uneven flange gasket alignment. Tighten line bolts evenly when installing the valve.

8. Center the valve in the line by making sure the mating flanges are aligned. Secure the valve in the line with the cap screws (keys 33 and 34, figures 11 and 12), line bolts (key 35, not shown), and hex nuts (key 44, not shown). Required clearances for installation of the line bolts and cap screws are

Page 4

V250 Valve

Instruction Manual

Form 5206

April 2004

shown in figure 2. When tightening the cap screws and line bolts, use accepted bolting procedures. Lubricate the studs or bolts and tighten the nuts in a crisscross sequence to ensure proper alignment of the valve with the flanges.

9. For hazardous atmosphere or oxygen service valves, read the following WARNING, and perform the instruction provided in the WARNING and provide the bonding strap assembly mentioned in Step 10 below if the valve is used in a hazardous application.

WARNING

The Design V250 is not necessarily grounded to the pipeline when installed. If the process fluid or the atmosphere around the valve is flammable, personal injury or property damage could result from an explosion caused by a discharge of static electricity from the valve components. If the valve is installed in a hazardous area, electrically bond the drive shaft to the valve.

Note

The packing is composed of all conductive packing rings (graphite ribbon packing) to electrically bond the shaft to the valve for hazardous area service or non-conductive PTFE packing rings. For oxygen service applications, perform the following step.

10. Attach the bonding strap assembly (key 41, figure 3) to the shaft with the clamp (key 40, figure

3), and connect the other end of the bonding strap assembly to the valve with the machine screw (key 43, figure 3).

11. Connect pressure lines to the actuator as indicated in the actuator instruction manual. When a manual actuator is used with a power actuator, install a bypass valve on the power actuator (if not already supplied) for use during manual operation.

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. Instructions are presented in this section for replacing the shaft seals, the ball seal or flow ring, the drive and follower shafts, the ball and bushing, and the valve outlet gasket.

Key number locations are shown in figure 11 for single seal and flow ring constructions, and in figure 12 for dual seal constructions.

WARNING

Personal injury or property damage can result due to a sudden release of pressure or process fluid if the pipe plug (key 42, figure 12) is removed while the valve is pressurized. To avoid such injury or damage, remove the pipe plug only when the control valve is isolated from the pressure system, or provide a hand valve to control relief of internal valve pressure to avoid personal injury or property damage.

A Design V250 valve with a dual seal construction contains a pipe plug port (key 42, figure 12) on the underside of the valve. This port can be used to relieve internal valve pressure for testing seal integrity when in the pipeline.

If the pipe plug port is to be used for testing seal integrity when the valve is in the pipeline, the plug should be replaced with a hand valve to allow controlled relief of valve pressure during seal leak rate testing.

WARNING

Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before starting disassembly:

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 either side of the valve.

D For dual seal valve constructions, remove pressure and drain the valve interior by removing the pipe plug (key

42).

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.

Replacing the Follower Shaft Seal

Both the follower and drive shaft seals should be replaced at the same time. Key number locations are shown in figure 11 or 12.

Perform this procedure if there is leakage around the follower shaft (key 7). Such leakage is an indication that the shaft seal, which includes the seal and a backup ring, (key 16) must be replaced. The following procedure may be performed with the valve in the pipeline.

drain the valve interior cavity. Shut off and disconnect all lines from the power actuator.

WARNING

Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

2. Unscrew the hex nuts (key 8) and remove the seal carrier (key 3) and shaft seal (key 16). Inspect and clean all parts and sealing surfaces on the seal carrier and follower shaft (key 7). Also, inspect and replace the O-ring (key 23) if necessary.

3. Install the new backup ring and shaft seal in the seal carrier.

4. Align the drive pin (key 28) with the drilled hole on the inner surface of the seal carrier, replace the seal carrier, and secure it with the hex nuts (key 8). Be careful not to damage the shaft seal or O-ring during replacement of the seal carrier.

Replacing the Drive Shaft Seal

Perform this procedure if there is leakage around the drive shaft (key 6). Such leakage is an indication that the shaft seal, which includes the seal and a backup ring, (key 16) must be replaced. This procedure may be performed with the valve in the pipeline. However, the actuator must be removed from the valve.

Note

The valve shaft’s packing surfaces are critical in obtaining a good seal. If the valve shafts are scratched, nicked or worn, replace or repair the valve shaft before installing the Live Loaded PTFE Packing parts.

Both seal rings, drive end and follower end, should be replaced at the same time.

1. Isolate the control valve from the line pressure, release pressure from both sides of valve, and drain the process media from both sides of the valve. For dual seal valve constructions, remove pressure and drain the valve interior cavity. Shut off and disconnect all lines from the power actuator.

5. Mount the actuator to the valve while referring to the Actuator Mounting section of this instruction manual and to the appropriate actuator instruction manual. If appropriate, install or replace the bonding

strap assembly and the clamp (key 41 and 40, figure 3).

Replacing Ball Seal or Flow Ring

Perform this procedure if the control valve is not shutting off properly (that is, leaking downstream). This procedure does not require removing the actuator from the valve. In addition to being shown in figures 11 and 12, key numbers are shown in figure 5 for the ball seal constructions and in figure 6 for the flow ring construction.

Removal

WARNING

Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

WARNING

The Hi-Ball (key 2) closes with a shearing motion. To avoid personal injury, keep hands, tools, and other objects away from the V-notch ball while stroking the valve.

CAUTION

Damage to the ball (key 2) may occur if the ball is not in the fully open position while the valve is being removed from the pipeline. If necessary, pressure the actuator temporarily to retain the ball in the open position while removing the valve from the pipeline.

2. With the ball in the fully open position, unscrew the line bolts and remove the valve from the pipeline.

3. Unscrew the cap screws (key 15, figures 11 and 12 only) and remove the seal protector ring (key 14) or the flow ring (key 14) from the inlet end of the valve. Then remove the O-ring (key 13), the ball seal (key 11), and the shim seals (key 10). The flow ring

construction will have no ball seal. For a dual seal construction, repeat this procedure on the other end of the valve.

4. Thoroughly clean all metal surfaces. Check all parts for damage, and replace damaged parts with new parts if necessary.

5. Proceed to the appropriate Installation procedure to install the removed parts.

Installation of Single or Dual Ball Seal

1. Check the seal surface of the valve (key 1) for scratches that may prevent the shim seals (key 10) from sealing off internal valve pressures.

2. Rotate the ball (key 2) to the closed position as indicated by the travel indicator scale (key 37, figures 10 and 11 only).

3. Place the appropriate number of shim seals into the valve:

D For 4 through 10-inch valve sizes, insert up to 6

shim seals into the valve.

D For 12 through 24-inch valve sizes, insert up to

7 shim seals into the valve.

4. Inspect the sealing surface of the ball seal (key

11) for possible damage. Then place the ball seal on top of the shim seals with any nicks or scratches facing away from the ball.

5. Add or remove the 0.25 mm (0.010 inch) thick shim seals to the valve until the ball seal firmly contacts the ball sealing surface (i.e., without rocking) when pressed tightly against the shim seal assembly.

6. Temporarily remove the ball seal, and remove 3 shim seals.

7. Replace the ball seal, and then place the O-ring (key 13) into the valve.

9. For dual seal constructions, repeat this procedure on the other end of the valve.

Installation of Flow Ring

1. Check the seal surface of the valve (key 1) for scratches that may prevent the shim seals (key 10) from sealing off internal valve pressures.

2. Rotate the ball (key 2) to the closed position as indicated by the indicator scale (key 37, figure 11 only).

3. Place the appropriate number of shim seals into the valve:

D For 4 through 10-inch valve sizes, insert 6 shim

seals into the valve.

D For 12 through 24-inch valve sizes, insert 7

shim seals into the valve.

4. Making certain the flow ring (key 14) is centered and does not contact the ball, secure the flow ring to the valve with the cap screws (key 15).

5. Measure the clearance between the flow ring and the ball with a wire gauge. Add or subtract shim

seals until the minimum clearance is 0.38 mm (0.015 inches) for valves used for forward flow and 0.76 mm (0.030 inches) for reverse flow.

6. Once minimum clearance is obtained, temporarily remove the flow ring.

7. Insert the O-ring (key 13) into the valve, and secure the flow ring to the valve with the cap screws (key 15).

Installing Live-Loaded PTFE Packing

These steps refer only to the Live Loaded PTFE Packing. Key number locations are shown in figures11, 12 and 13.

Note

Both seal rings, drive end and follower end, should be replaced at the same time.

1. Remove the hex nuts (key 8) from the seal carrier (key 17 on the drive shaft end and key 3 on the follower shaft end). Remove the spacer (key 22). On 4-, 12- and 24-inch sizes, the stud bolt (key 4) will need to be removed. The drive pin (key 28) needs to be removed from the outboard end of the valve body.

2. Replace the seal carrier and spacer with the new packing box (key 17 or 3). To keep the ball properly centered inside the valve body, the bushing spacer shims may need to be added or removed (see the Installation of Single or Dual Ball Seal section).

3. Secure the packing box with hex nuts (key 8), for 6-,8-, 10-, 16, or 20-inch sizes, or socket head cap screw (key 4), for 4-, 12-, or 24-inch sizes. Lubricate the hex nuts or cap screws and tighten them. Be careful not to damage the O-ring during installation of the packing box.

4. Install the packing box studs (key 100).

Note

The Belleville springs must be stacked properly and packing box parts must be assembled in the correct order, if

the packing parts are to function properly.

5. Install the packing ring, female and male adaptors, anti-extrusion rings, and packing box rings (keys 105, 106 and 107). Be sure to install the packing rings in the order and quantity shown in figure 13.

6. Install the spring pack assembly (key 103 or 104), which includes the Belleville springs, packing follower, and O–ring. The O-ring is a non-functional part used to retain the packing springs during assembly.

7. Install the packing flange (key 102) on the shaft. Then lubricate and install the packing nuts (key 101), hand tightening them. Apply lubricant to the stud threads, internal nut threads and contacting face of the nut. Packing flanges with flats on the sides may need to be oriented with the mounting bracket so the flange will fit between the legs of the bracket.

8. To obtain optimum maximum benefit from the packing system, tighten the packing flange nuts and compress the Belleville springs to their Target Load. The Belleville springs are designed to provide optimum performance at their Target Load, 85% of their maximum deflection/compression.

To obtain the Target Load compression, tighten the packing flange nuts alternately and evenly, keeping the packing flange parallel with the valve flange, until the Belleville springs are compressed 100%. Then loosen each packing flange nut one half turn (180_ of rotation).

Replacing Drive Shaft, Follower Shaft, Ball, Bushings, and Valve Outlet Gasket

This procedure is to be performed to replace the valve ball, the drive shaft, and the follower shaft, if the ball does not rotate in response to rotation of the actuator end of the drive shaft, or if there is leakage around the outlet gasket.

Disassembly

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 actuator lever off the valve shaft could move the ball (key 2)

from the centered position, causing damage to the ball, the ball seal (key

11), and the valve (key 1). Use care when removing the actuator

lever and, 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 the valve.

1. Remove the cap screws (key 29) from the actuator mounting yoke and, while referring to the actuator instruction manual for assistance, remove the actuator. If appropriate, remove the clamp and bonding strap assembly (key 40 and 41, figure 3).

2. Remove either the seal protector ring (key 14) or the flow ring (key 14) from the inlet end of the valve assembly by following steps 1, 2, and 3 of the Replacing Ball Seal or Flow Ring section. For dual seal constructions, note that this procedure should be repeated on the outlet end of the valve.

3. Proceed as appropriate: D For single seal constructions and flow ring

constructions (figure 11 only), remove the cap screws (key 27).

D Then, remove the valve outlet (key 5) and

gasket (key 12).

Note

Perform the following step with the inlet end of the valve assembly facing upward and with the ball (key 2) in the fully open position.

4. Remove the hex nuts (key 8) from the follower

shaft (key 7) side of the valve. Then remove the seal carrier (key 3). Inspect and replace the seal (key 16) and O-ring (key 23) if necessary.

follower shaft bore of the valve.

D Then, while being careful not to damage the

sealing surfaces of the ball, remove the ball through the outlet end of the valve.

13. Inspect and, if necessary, replace all parts.

Then, proceed to the assembly procedure below.

Assembly

1. Position the ball (key 2) so that it is firmly

supported inside the valve (key 1). Insert a ball support post (see figure 7) into the follower shaft (key 7) bore of the valve. Position the ball support post so that the ball will be supported firmly inside the valve body cavity while performing steps 2 through 5.

CAUTION

Damage to the valve assembly and downstream equipment could occur if the shaft retainer (key 25) should become disengaged from the drive shaft (key 6) during operation of a Design V250 control valve assembly. To prevent such damage, make sure that the internal threads in the Polygon coupling end of the drive shaft and the external threads of the shaft retainer are cleaned thoroughly before applying Loctite Primer N or T and Loctite No. 271 or equivalent sealant (key 30) as described in step 5 of this assembly procedure.

2. Insert the drive shaft (key 6) into the drive shaft side of the valve and ball assembly. When inserting the drive shaft, make sure that the index mark on the Polygon coupling end of the drive shaft is aligned with the index mark on the hub of the ball. Refer to figure 8 for the location of these index marks.

3. Install the thrust spacer (key 21) into the drive shaft side of the valve and position it so that it is in contact with the ball hub. Then, install the thrust washer (key 19) and the bushing (key 20).

Form 5206 April 2004

4. Insert the washer (key 24) into the ball. Lubricate

the exposed surface of the washer with a good quality grease or lubricant.

CAUTION

Improper tightening of the shaft retainer (key 25) could allow the shaft retainer to become disengaged from the drive shaft (key 6) during operation of a Design V250 control valve assembly. This could cause damage to the valve assembly and downstream equipment. To prevent such damage, make sure that the shaft retainer is tightened to the appropriate torque value listed in table 4.

5. Apply Loctite Primer N or T and Loctite No. 271

or equivalent sealant (key 30) to the threads of the shaft retainer (key 25). Then, install the shaft retainer into the inside end of the drive shaft. Tighten the shaft retainer to the torque value listed in table 4.

CAUTION

Damage to the valve assembly and downstream equipment could occur if the retainer screw (key 32) should become disengaged from the follower shaft (key 7) during operation of a Design V250 control valve assembly. To prevent such damage, make sure that the internal threads in the inside end of the follower shaft and the external threads of the retainer screw are cleaned thoroughly before applying Loctite Primer N or T and Loctite No. 271 or equivalent sealant (key 30) as described in step 8 of this assembly procedure.

6. While maintaining firm support of the ball (key 2),

remove the ball support post through the follower shaft bore of the valve. Then install the follower shaft into the valve. When installing the follower shaft, make sure that the drilled hole containing the two pins (key 9) is aligned with the two notches machined on the inside surface of the ball hub.

7. Temporarily position the follower shaft so that it

protrudes slightly into the flow bore of the ball. Place the split ring (key 31) on the end of the follower shaft. Then, return the follower shaft to its original position.

CAUTION

Improper tightening of the retainer screw (key 32) could allow the retainer screw to become disengaged from the follower shaft (key 7) during operation of a Design V250 control valve assembly. This could cause damage to the valve assembly and downstream equipment. To prevent such damage, make sure that the retainer screw is tightened to the appropriate torque value listed in table 4.

8. Apply Loctite Primer N or T and Loctite No. 271 or equivalent sealant (key 30) to the threads of the retainer screw. Then, install the retainer screw into the inside end of the follower shaft until it is at least flush with the end surface of the follower shaft. Make sure that the drilled hole containing the two pins (key

9) is still aligned with the two notches machined on the inside surface of the ball hub. Tighten the retainer screw to the torque value listed in table 4.

9. Install the thrust spacer (key 21) into the follower shaft side of the valve and position it so that it is in contact with the ball hub. Then, install the thrust washer (key 19) and the bushing (key 20).

10. Center the ball inside the valve along the axis of both the drive shaft and the follower shaft. The maximum deviation in measurement between the valve and ball from one side to the other should be no more than 0.005 inches (0.127 mm) as shown in figure 9.

11. In order to maintain proper centering of the ball inside the valve, the bushing spacer shims (key 18) must be installed in the following manner.

D For the drive shaft side of the valve, install several bushing spacer shims around the drive shaft and into the valve. Then, temporarily install the spacer (key 22) and the seal carrier (key 17). Repeat this process, but add only one more bushing spacer shim into the valve each time, until contact between the seal carrier and the valve is broken. Then, remove one bushing spacer shim and secure the spacer and seal retainer to the valve with the hex nuts (key 8). Be careful not to damage the seal (key

16) or O-ring (key 23) during replacement of the seal carrier.

D For the follower shaft side of the valve, install several bushing spacer shims around the follower shaft and into the valve. Then, temporarily install the spacer (key 22) and the seal carrier (key 3). Repeat this process, but add only one more bushing spacer shim into the valve each time, until contact between

Actuator Mounting

Use the appropriate actuator instruction manual and figure 10 of this instruction manual when changing actuator styles and positions. The actuator may be either right- or left-hand mounted. Figure 10 shows the correct lever/shaft orientation for both left-hand mounting and right-hand mounting configurations.

Travel Adjustment

Actuator travel adjustment can be performed with the valve either in or out of the pipeline. Key

numbers referenced in the following procedures are shown in figure 11 for single seal and flow ring constructions and in figure 12 for dual seal constructions.

D For valve assemblies in the pipeline:

1. Rotate the ball (key 2) to either the open or closed position as indicated by the travel indicator scale (key 37) on the outboard end of the valve.

2. Adjust the actuator as described in the appropriate actuator instruction manual until the arrow stamped on the end of the follower shaft (key

7) is fully aligned with the open or closed position on he travel indicator scale.

D For valve assemblies out of the pipeline, proceed as follows:

1. Rotate the ball to the fully open position. The fully open position is achieved when the inside surface of the ball bore (key 2) is completely square with the line flange gasket surface of the seal protector ring (key 14) or flow ring (key 14).

2. Adjust the actuator as described in the appropriate actuator instruction manual until the inside surface of the ball bore is at right angles to the line flange gasket surface of the seal protector ring or flow ring.

3. Adjust the travel indicator scale (key 37) until the arrow stamped on the end of the follower shaft (key

7) is fully aligned with the open position.
