Installation

Key numbers referenced in this section are shown in Figure 10, unless otherwise indicated.

WARNING:

• Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury.
• Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed where service conditions could exceed the valve body rating or the mating pipe flange joint rating. Provide a relief valve for overpressure protection as required by government or accepted industry codes and good engineering practices.
• Consult your process or safety engineer for any additional measures required to protect against process media.

CAUTION: Valve configuration and materials were selected for specific pressure, temperature, and fluid conditions. Responsibility for process media safety and material compatibility rests with the purchaser and end-user. Do not apply other conditions without contacting Emerson sales.

Install the valve with the drive shaft in the horizontal position as shown in Figure 1.

CAUTION: To maximize seal life, the drive shaft should be in the horizontal orientation during service. Contact your Emerson sales office for evaluating vertical drive shaft installations.

1. If storing the valve before installation, protect flange mating surfaces and keep the valve cavity dry and free of foreign material.
2. Install a three-valve bypass around the control valve assembly if continuous operation is necessary during inspection and maintenance.
3. Mounting the Actuator: The valve is typically shipped with the actuator mounted. Factory adjustments are made before shipment. If the valve and actuator were purchased separately or the actuator was removed, mount the actuator per the Actuator Mounting section.
4. Ensure the valve and adjacent pipelines are free of foreign material that could damage seating surfaces.
5. Align mating line flanges. Use flange gaskets (flat sheet or spiral wound) compatible with the process fluid.
6. Refer to Figure 2 for required clearance and stud length. Lubricate studs with anti-seize lubricant.
7. Install the valve using studs and nuts to connect flanges. The seal protector ring end requires longer line flange studs than standard (see Figure 2).

Table 4. Required Clearances for Installation of Fisher V150 and V300 Valves

(1) ASME B16.10 (Short) applies to NPS 14 and 16 valves only. (2) Inlet flange stud bolt length is longer than standard. (3) NPS 20, CL150 valves do not comply with ASME B16.10 (Short). (4) Valve body mates with NPS 24 ASME CL150 flanges. (5) If Cavitrol Hex trim is installed, A and B dimensions increase by 12.7 mm (1/2-inch). (6) For Cavitrol Hex trim, dimension M bolt length is required for both inlet and outlet flange ends.

Figure 2. Required Clearances for Installation: This diagram illustrates the necessary space around the valve for proper installation, showing dimensions A, B, M, and N.

Do not use standard-length studs for the seal protector end. Refer to Figure 2 for required lengths. Install remaining studs and tighten nuts in a criss-cross sequence to ensure proper gasket loading.

Safety Precautions

WARNING: The valve drive shaft may not be grounded to the pipeline. In hazardous areas, electrically bond the drive shaft to the valve to prevent static electricity discharge if the process fluid or atmosphere is flammable.

Standard PTFE packing is composed of a carbon-filled PTFE adaptor with PTFE V-ring packing. Graphite packing uses conductive graphite ribbon rings. Alternate shaft-to-valve body bonding is available for hazardous areas where standard packing is insufficient.

For hazardous applications, attach the optional bonding strap assembly (key 131, Figure 4) to the drive shaft (key 6) with clamp (key 130) and connect to the valve body with a cap screw (key 23).

Connect pressure lines to the actuator per its instruction manual. If an auxiliary manual actuator is used with a power actuator, install a bypass valve on the power actuator for manual operation.

WARNING: Personal injury can result from packing leakage. Packing is pre-tightened, but may require readjustment for specific service conditions. Consult your safety engineer. If ENVIRO-SEAL live-loaded packing is installed, initial readjustment may not be required; refer to the ENVIRO-SEAL Packing System manual (D101643X012).

Maintenance

Valve parts are subject to normal wear and require inspection/replacement based on service severity.

WARNING: The Vee-ball closes with a cutting motion. Keep hands, tools, and objects away from the ball during stroking. Avoid injury from sudden pressure release. Before maintenance:

• Do not remove the actuator from a pressurized valve.
• Disconnect actuator operating lines (air, power, control signal) and ensure the actuator cannot open or close the valve.
• Use bypass valves or shut off process flow to isolate the valve. Relieve and drain pressure from both sides.
• Vent power actuator loading pressure.
• Use lock-out procedures.
• Always wear protective gloves, clothing, and eyewear.
• The packing area may contain pressurized process fluids. Process fluids may spray out under pressure when removing packing hardware.
• Consult your process or safety engineer for additional measures.

Packing Maintenance

Key numbers are shown in Figure 10. A detailed view of packing is in Figure 3.

For ENVIRO-SEAL Packing System, refer to its specific instruction manual (D101643X012) and Parts List section.

Stopping Leakage

For PTFE V-ring packing, leakage around the packing follower (key 17) and packing flange (key 40) can be stopped by tightening packing follower nuts (key 20).

If leakage persists and the drive shaft (key 6) is not worn or nicked, check for nicks, scratches, or corrosion on the packing box wall.

If leakage cannot be stopped, remove and replace packing. Inspect the drive shaft and packing box before installing new parts.

Packing Replacement

Do not remove the actuator while the valve is in the pipeline. Valve/actuator adjustments must be made with the valve out of the pipeline.

Disassembly

1. Isolate the valve, release pressure from both sides, and drain process media. For power actuators, shut off pressure lines, release actuator pressure, and disconnect lines. Use lock-out procedures.
2. Remove line bolting, remove the valve from the pipeline, and place the assembly on a protected surface with the seal protector ring facing up.
3. Remove the actuator cover. Note the actuator and lever orientation relative to the drive shaft (see Figure 8).

WARNING: When the actuator is removed, the ball/shaft assembly may rotate suddenly, causing personal injury. Carefully rotate the ball to a stable position after actuator removal.

Figure 3. Packing Arrangements: This diagram illustrates the Standard Packing Assembly (PTFE V-ring and Graphite Ribbon) and the ENVIRO-SEAL Packing Systems (PTFE and Graphite).

Ball Seal Replacement

Perform this procedure if the valve is not shutting off properly or if seal inspection is necessary. Remove the actuator/valve assembly from the pipeline.

The actuator may remain mounted during inspection/replacement. Ball seal assembly details are in Figure 5.

Handle seal protector ring, seal, and other parts (keys 3, 11, 13, 37) carefully to prevent damage. A new gasket (key 15) is required when the seal protector ring (key 3) is removed.

CAUTION: Due to the Vee-ball shape, do not rotate the ball through the ball seal at any time, as the seal could be damaged.

For flow ring constructions, disregard instructions for seals and seal parts, but follow procedures for removing the seal protector ring.

Disassembly

WARNING: If the actuator is removed, the ball/shaft assembly may rotate suddenly, causing personal injury. Carefully rotate the ball to a stable position. Lock the ball if necessary.

Key numbers are shown in Figure 10.

1. Isolate the valve, release pressure, and drain process media. For power actuators, shut off pressure lines and release actuator pressure.
2. Remove line bolting, remove the valve/actuator assembly from the pipeline, and place on a protected surface with the seal protector ring facing up. Carefully rotate the ball to the open position.
3. Remove retainer screws (key 21). Carefully remove the seal protector ring and gasket (keys 3 and 15).
4. For composition seals: Remove the seal (key 11) from the valve body (key 1).
5. For HD metal seals: Push the metal seal (key 11) out of the seal protector ring (key 3). Remove the radial seal (key 37). Inspect/clean/replace parts as necessary.

It may be necessary to tap the HD metal seal with a soft punch and hammer; avoid damaging seal protector ring surfaces.

Inspect gasket and sealing surfaces (valve body key 1, ball key 2, ball seal key 11, seal protector ring key 3) for damage.

If ball, drive/follower shafts, or bearings (keys 2, 6, 9, 10) need replacement, proceed to Bearing and Ball Maintenance. If only the seal needs replacement, proceed to assembly.

Assembly

Refer to Figure 5 for part and key number locations.

1. Clean all parts thoroughly. Ensure sealing surfaces are in good condition. If valve was installed between flanges, always replace the gasket (key 15).
2. Lift and place the valve with the outlet flange flat on a protected surface. Rotate the ball to the closed position. The inlet flange should be up, with the ball centered.
3. Ensure the ball cannot rotate during assembly (refer to Warning on page 9).
4. For valves with composition ball seals: Install the composition seal (key 11) into the valve body, install the gasket (key 15) on the valve body, and install the seal protector ring (key 3) into the valve body. Proceed to step 6.
5. For valves with HD metal seals: Lubricate and install the radial seal (key 37) into the seal protector ring groove, ensuring the open side faces away from the ball. Install the wave spring (key 13) on the seal protector ring. Install the HD metal seal (key 11) into the seal protector ring, past the radial seal, ensuring it is level. Lubricate the HD metal seal seat and ball face for break-in.
6. Install the HD metal ball seal/seal protector ring assembly into the valve body (key 1). Proceed to step 6.
7. Install retaining screws (key 21) securing the seal protector ring (key 3) to the valve body (key 1) and tighten them.
8. If necessary, refer to Packing Maintenance procedures to install packing. Install the actuator per its manual.

Bearing and Ball Maintenance

Disassembly/assembly of bearings and ball requires loosening the ball seal and valve packing. Refer to Packing Maintenance to remove the actuator and Ball Seal Replacement to remove the seal.

Install an "eye" bolt into the threaded hole within the ball cavity (see Figure 10) for lifting and controlling ball rotation. Return to this section after ball seal disassembly.

Place the valve on a protected surface with the seal side down before removing/installing the ball and bearings. Key numbers are shown in Figure 10.

Disassembly

WARNING: The ball may rotate suddenly when the actuator is removed, causing personal injury. Carefully rotate the ball to a stable position. Provide a hoist to support the ball to prevent it from falling and damaging sealing surfaces.

1. Lift and set the valve on the edge of the flanges with the ball in the open position. Block the drive end of the valve body to hold the shaft horizontally.
2. Drive out the pins (key 7) from the drive shaft (key 6) and follower shaft (key 9). Pins are tack welded; break the weld by inserting a pin punch opposite the tack weld side.
3. Lift and place the valve on the working surface with the seal side down. The ball's contoured sealing surface should rest on the surface.
4. Remove flange nuts (key 47), bottom flange (key 44), and gasket (key 45). Use a hoist to lift the valve body slightly. Ensure the ball's sealing surface is not damaged when removing the follower shaft (key 9).
5. Push the follower shaft (key 9) into the ball's center. For metal bearings, remove the thrust washer (key 38).
6. Pull the drive shaft (key 6) out of the valve body. For metal bearings, remove the thrust washer (key 38).
7. Removing the bearings (key 10):
• For PEEK bearings, remove by hand. If tight, pull or drive out with slight pressure.
• For metal bearings, use a press and ram to remove drive shaft bearings from the valve body. Refer to Figure 7 for ram dimensions. Use a blind-hole bearing puller for the follower shaft bearing from the bottom flange (key 44).

Note: Bearing (key 10) position is critical for shutoff performance. Ensure correct placement.

Clean all surfaces. Pins need to be tack welded upon reassembly; remove excess weld material.

Assembly

1. Inspect all sealing surfaces for good condition (no scratches/wear). Clean all parts.
2. Installing bearings (key 10):
• For PEEK bearings, install by hand. The flanged end should touch the drive shaft bearing support surface (Figure 10). Install bearing into the bottom flange (key 44), ensuring the flange touches the bottom flange surface.
• For metal bearings, use a press and ram to install into the valve body (key 1) and bottom flange (key 44). Press until flush with the valve body. Tolerance: flush to 1.5 mm (0.06 inches) inside the bearing bore. Bearings should not protrude into the flow cavity.

WARNING: Support the ball to prevent it from falling into the valve body cavity, which could damage it.

3. Installing the ball, drive and follower shafts (keys 2, 6, and 9):
• Place the valve body (key 1) on a protected surface with the seal side flat. Ensure the ball's splined ear aligns with the packing box side of the valve body.
• Using an "eye" bolt, lift the ball and lower it into the valve body through the outlet flange, splined ear first. Align the splined ball ear with the drive shaft bearing support (Figure 10). Allow the ball to rest on the contoured sealing surface.
• Lift the valve body to insert the drive shaft (key 6) through the shaft bore and bearing (key 10) into the ball's splined ear. Ensure "O" marks on the shaft and ball ear align. Insert the drive shaft pin (key 7).
• Align the follower shaft bore with the opening for the lower flange (key 44). Insert the follower shaft into the ball.
• Place gasket (key 45) on the bottom flange (key 44). Insert the bottom flange into the valve body, onto the follower shaft. Thread bottom flange nuts (key 47) onto studs (key 46) and hand tighten.
• Installing the pins (key 7): Tack weld both pins (key 7) to the ball ears with a 10 mm (3/8-inch) diameter weld. Good weld penetration is required.
• Tighten bottom flange nuts to specified torque values: NPS 14: 102 N•m (75 lbf·ft); NPS 16: 141 N•m (104 lbf·ft); NPS 20: 176 N•m (130 lbf·ft).
• Lift and place the valve with the outlet flange face flat on a protected surface. Rotate the ball to the closed position. The inlet flange should be up.
• Refer to Ball Seal Replacement procedures to install the ball seal and seal protector ring.

Cavitrol Hex Replacement

Disassembly

WARNING: Observe safety warnings at the beginning of the Maintenance section.

1. Isolate the valve, drain process media, and remove the valve/actuator assembly as described in Ball Seal Replacement.
2. Place the valve on a protected surface with the body outlet flange facing up.
3. Remove the four fasteners (key 67) securing the Cavitrol Hex trim to the valve body.

WARNING: Do not use the four threaded lifting holes in the Cavitrol Hex trim to lift the complete valve assembly. These holes are only for lifting the trim itself. All lifting and rigging must comply with applicable regulations and standards.

4. Install hoist rings or lifting equipment into the four 3/8"-16 threaded holes in the Cavitrol Hex trim flange.
5. Remove the Cavitrol Hex trim and place on a protected surface.
6. Remove gasket (key 65) from the valve body outlet flange.

Assembly

The Cavitrol Hex anti-cavitation trim (key 64) is available for NPS 14, 16, and 20 V150 and V300 flanged, raised-face constructions. Retrofitting requires special body machining. Contact your Emerson sales office for details.

Note: The Cavitrol Hex trim adds 12.7 mm (1/2-inch) to the face-to-face dimension. Refer to Table 4 for flange stud length.

1. Install the Cavitrol Hex trim (key 64) last, after the Vee-Ball valve body assembly is complete. Recommended orientation is with the body outlet flange facing up.
2. Ensure the ball is in the open position.
3. Place gasket (key 65) over the body outlet flange serrated surface (Figure 11).
4. Install hoist rings or lifting equipment into the four 3/8"-16 threaded holes in the Cavitrol Hex flange.

Table 6. Fisher Cavitrol Hex Dimensions and Weight

Actuator Mounting

Standard flow direction is with the seal protector ring (key 3) facing upstream. Install the valve with the drive shaft horizontal and the ball closing in the downward direction (see Figure 8).

WARNING: The Vee-ball (key 2, Figure 10) closes with a cutting motion. Keep hands, tools, and objects away from the ball while stroking the valve.

Actuator travel must be adjusted before installing the valve in the pipeline, as it is not possible to accurately determine the closed position once the valve is in the line.

Figure 8. Index Mark for Actuator Lever Orientation: This table illustrates various actuator mounting styles (A, B, C, D) and their corresponding lever orientations for valve open/closed positions, and actuator positions 1-4.

The actuator can be right or left-hand mounted in any of four positions as shown in Figure 8.

Note: Right-hand mounting: Actuator on the right side of the valve (viewed from inlet). Left-hand mounting: Actuator on the left side of the valve (viewed from inlet).

Changing from right- to left-hand mounting (or vice versa) requires a different drive shaft and ball. Refer to Bearing and Ball Maintenance and the Parts List.

Note: Mounting the valve with the ball rotating to the top (left-hand position) may require a non-standard ball that rotates clockwise to close. Refer to Figure 8 or contact Emerson sales office.

Determining Open Position

The valve must be removed from the pipeline to check the ball position.

1. Rotate the ball to the open position (shown in Figure 9).
2. Adjust actuator linkage until the open position is obtained, using the appropriate actuator instruction manual procedures.
3. Stroke the valve to the closed position.

Ensure the actuator does not stroke the ball more than 90 degrees when rotating to the closed position (see Figure 9).
