Do not install, operate, or maintain an SS-84PSV4 valve without being fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you have any questions about these instructions, contact your Emerson Process Management sales office before proceeding.

Maximum Ball Rotation

Standard: Ball rotates counterclockwise to close when viewed from actuator side of valve

Ball rotation is 80 degrees

Valve/Actuator Action

Push‐down‐to‐open (extending actuator rod opens valve.) See actuator manual for details

Description

The SS-84PSV4 Vee-Ball valve (figure 1) with a V‐notch ball is used in throttling or on‐off service. The SS-84PSV4 valve is an NPS 4 schedule 120 buttweld construction, per Westinghouse weld end configuration requirements. The splined valve shaft of this valve connects to a variety of rotary‐shaft actuators.

Specifications

Specifications for these valves are shown in table 1.

Principle of Operation

The Vee-Ball and machined body combine to create smoothly transitioning flow geometry which enables efficient flow through the valve. The drive shaft and follower shaft center the ball in the flow stream to minimize dynamic torque and permit easy ball rotation.

The ball rotates clockwise out of the sleeve seal to a standard open rotation of 80 degrees. In the closed position, the sleeve seal is spring loaded against the ball to create an effective seal. The drive linkage between the ball and shaft has been designed for minimal lost motion using a “spline connection” on the shaft and ball.

Installation

Key numbers in installation procedures are shown in figure 8 unless otherwise indicated.

WARNING

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

Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed where service conditions could exceed either the valve body rating or the mating pipe flange joint rating. To avoid such injury or damage, provide a relief valve for overpressure protection as required by government or accepted industry codes and good engineering practices.

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

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

WARNING

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 with process media rests solely with the purchaser and end‐user. To avoid possible personal injury and because some valve/trim material combinations are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first contacting your Emerson Process Management sales office.

WARNING

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

Note

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 bond the shaft to the valve (see the following step).

1. If the valve is to be stored before installation, protect the buttweld ends and keep the valve body cavity dry and free

of foreign material.

2. The valve is normally shipped as part of a control valve assembly, with an actuator mounted on the valve. If the

valve and actuator have been purchased separately or if the actuator has been removed, mount the actuator according to the Actuator Mounting section and the appropriate actuator instruction manual.

3. Standard flow direction is forward flow, spherical face of the ball is upstream.

4. Install the valve in a horizontal pipeline with the drive shaft in the horizontal position.

CAUTION

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

5. The actuator is right‐hand mounted with the shaft in a horizontal orientation as shown in figure 1. If necessary,

refer to the appropriate actuator instruction manual for actuator installation and adjustment procedures.

CAUTION

Ensure the valve and adjacent pipelines are free of foreign material that could damage the valve seating surfaces.

6. Be certain the valve and adjacent pipelines are free of any foreign material that could damage the valve sealing

surfaces.

7. Be sure the pipelines are in line with each other.

8. Use accepted pipeline piping and welding practices when installing the valve in the pipeline.

9. Connect pressure lines to the actuator as indicated in the actuator instruction manual. When an auxiliary manual

actuator is used with a power actuator, install a bypass valve on the power actuator (if one is not supplied) for use during manual operation.

WARNING

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

10. Verify that gap “A”, in figure 7, is closed before pressurizing the pipeline.

WARNING

Lifting Guidelines

CAUTION

Care must be taken when lifting the valve/actuator assembly to ensure the accessories and tubing are not damaged in the process. The entire assembly with accessories weighs approximately 340 kg (750 lb). Make sure to use appropriate lifting straps/eyebolts/hoists capable of lifting this weight.

Lifting Valve/Actuator Assembly

To lift the assembly, insert 3/4-10 eyebolts into the two tapped holes on the top of the valve body. These two tapped holes will carry most of the weight, but the assembly must be balanced using a strap on the 1052PSV casing as shown in figure 2. The ends of the strap will be positioned underneath two L-shaped flanges or through eyebolts. Figure 2 shows L-shaped flanges attached to the casings. An alternative casing lift method is to use 3/8 inch eyebolts positioned 180 degrees apart. Use protective pads between the strap and the casing to help prevent damage to the painted surface. Torque the 3/8-24 cap screws or eyebolts and nuts to 20 lbf•-ft. The assembly can now be lifted using a hoist capable of leveling these lifting points.

Lifting Valve Only

To lift the valve, insert 3/4-10 eyebolts into the two tapped holes on the top of the valve body. These two tapped holes will carry most of the weight, but the assembly must be balanced using a strap underneath the valve bottom flange (key 5 in the SS-84PSV4 instruction manual, D103416X012), as shown in figure 2. The assembly can now be lifted using a hoist capable of leveling the 3 lifting points.

Lifting Actuator Only

The actuator with accessories shall be lifted by the casing flange as shown in figure 2. Figure 2 shows L-shaped flanges attached to the casings. An alternative casing lift method is to use 3/8 inch eyebolts positioned 180 degrees apart. Use protective pads between the strap and the casing to help prevent damage to the painted surface. Torque the 3/8-24 cap screws or eyebolts and nuts to 20 lbf•ft. A single hoist lift point on the strap will balance and lift the actuator in a level manner.

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 8, unless otherwise noted.

WARNING

The Vee‐ball closes with a shearing, cutting motion, which could result in personal injury. To avoid injury, keep hands, tools, and other objects away from the Vee‐ball while stroking the valve.

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 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

from both sides of the valve. Drain the process media from both sides of the valve.

D Vent the power actuator loading pressure and relieve any actuator spring precompression.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations.

D The valve packing area may contain process fluids that are pressurized. Process fluids may spray out under pressure

when removing the packing hardware or packing rings.

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

media.

Packing Maintenance

Key numbers in this procedure are shown in figure 8, unless otherwise noted. A detailed view of the packing is also shown in figure 7.

Refer to the Parts List section of this manual for individual parts.

If the packing is relatively new and tight on the drive shaft (key 9), and if tightening the packing nuts (key 27) does not stop leakage, it is possible that the drive shaft is worn or nicked so that a seal cannot be made. If the leakage comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches on the packing box wall. Inspect the drive shaft and packing box wall for nicks or scratches while performing the following procedure.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the

process media from both sides of the valve. If using a 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.

2. Remove the actuator cover (key 33 from the Fisher 1052PSV Size 60 Rotary Actuator Instruction Manual,

D103407X012).

WARNING

When the actuator is removed from the valve, the ball/shaft assembly may suddenly rotate, with a shearing, cutting motion, which could result in personal injury. To avoid injury, carefully rotate the ball to a stable position after the actuator is removed.

CAUTION

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

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

3. Remove the clamped lever (do not loosen the actuator turnbuckle adjustment), and remove the actuator mounting

fasteners. (If necessary, refer to the 1052PSV actuator instruction manual for assistance.

WARNING

Personal injury could result from packing leakage. Do not scratch the drive shaft or packing box wall while removing packing parts in the following procedure.

Note

Do not change the position of the stop cap screws and nuts (key 17, 19, and 18) in the following step.

4. Remove the live-loaded packing parts (see figure 7, keys 27, 26, 160, 16, and 25)

5. Remove the hex nuts (key 14) and bottom flange (key 5). The bushing (key 7) should come out with the bottom

flange, otherwise remove the bushing now.

6. After removal of the spiral wound gasket (key 11), inspect the sealing surfaces on the bottom flange and the valve

body.

7. Rotate the VeeBall counterclockwise (ccw) 180_ out of the closed position. This can be accomplished using the

following method:

a. Use the actuator lever and rotate the drive shaft (key 9) by hand.

b. Use a 7/8 inch hex socket wrench and rotate the Vee-Ball assembly (key 2) by the flats on the follower shaft.

8. Remove the Vee-Ball assembly from the valve body, taking care not to damage the sealing surface of the ball.

9. Remove the drive shaft/collar assembly, bushing, and thrust washer (keys 9, 7, and 8) from the valve body. If

needed, use a rubber mallet or blunt tool to tap the drive shaft out from the actuator end of the valve body. Take care not to damage the drive shaft spline.

5. Install the carbon piston ring (key 22) and the retaining ring (key 29) onto the sleeve seal (key 20).

6. Install the sleeve seal assembly in the valve body through the bottom flange hole.

7. Install the thrust washer (key 8) on the drive shaft / thrust collar / pin assembly (key 9). Locate the thrust washer on

the actuator side of the thrust collar in figure 3.

8. Install a journal bushing (key 7) on the drive shaft / thrust collar / pin assembly (key 9) on the side next to the

VeeBall splined connection end. Note: Place the smaller OD end next to the thrust collar (see figure 3).

9. Install the Vee-Ball assembly (key 2) on the drive shaft (key 9). Note: The splined connection is missing a tooth

allowing One-Way assembly.

10. Make sure the sleeve seal assembly has remained all the way in the valve body and that the wave spring is still

engaged with the valve body. Orient the Vee-Ball and shaft assembly (see figure 4) with the Vee-Ball positioned 180 degrees out of the sleeve seal seat (key 20). Install into the valve body through the bottom flange hole. Use care to avoid any scratches to the drive shaft as it slips through the bottom of the packing box area in the valve body.

11. The outer end of the Vee-Ball follower shaft has a 7/8 inch hex. Use a 7/8 inch socket to assist rotating the Vee-Ball

into the sleeve seal seat. With the ball and shaft assembly held tightly against the thrust washer (key 8), rotate the Vee-Ball clockwise (cw as viewed from the bottom flange side of the valve body) allowing the vee contour to start to engage the sleeve seal seat.

CAUTION

In the following step, if the Vee-Ball is accidentally rotated too far, allowing a gap from the trailing edge of the Vee-Ball, DO NOT rotate counter clockwise (ccw) back into the seat. Continue to rotate around clockwise (cw) and repeat step 15.

12. Visually rotate the Vee-Ball to the closed position until it is centered in the seat. Final closed position will be

accomplished using the Precise Valve/Actuator Closed Position Adjustment procedure in the 1052PSV actuator instruction manual.

13. During the remaining body assembly procedures care should be taken to keep the Vee-Ball in the closed position.

Note: The Vee-Ball open position is restricted to 80 degree rotation from the closed position so the vee-notch contour on the Vee-Ball will retain the sleeve seal package in place.

9. Install the Vee-Ball assembly (key 2) on the drive shaft (key 9). Note: The splined connection is missing a tooth

allowing One-Way assembly.

10. Make sure the sleeve seal assembly has remained all the way in the valve body and that the wave spring is still

11. The outer end of the Vee-Ball follower shaft has a 7/8 inch hex. Use a 7/8 inch socket to assist rotating the Vee-Ball

CAUTION

12. Visually rotate the Vee-Ball to the closed position until it is centered in the seat. Final closed position will be

accomplished using the Precise Valve/Actuator Closed Position Adjustment procedure in the 1052PSV actuator instruction manual.

13. During the remaining body assembly procedures care should be taken to keep the Vee-Ball in the closed position.

Note: The Vee-Ball open position is restricted to 80 degree rotation from the closed position so the vee-notch contour on the Vee-Ball will retain the sleeve seal package in place.

14. Install a journal bushing (key 7) into the bottom flange (key 5). The small OD end of the bushing is placed toward

the bottom flange.

15. Install the spiral wound gasket (key 11) in the groove on the valve body (key 1).

16. Coat the twelve 7/8-9 x 5.25 bottom flange studs (key 3) with nuclear grade anti-seize lubricant up to the

deformed thread. Thread the studs into the valve body (key 1) until hitting the deformed thread.

17. Install the bottom flange and bushing over the Vee-Ball follower shaft and tightly against the spiral wound gasket.

Note: The Vee-Ball / Follower shaft assembly may be slightly off center due to the wave spring loading, but will self-center.

18. Lubricate the twelve 7/89 bottom flange nuts (key 14) with nuclear grade anti-seize lubricant. Install the nuts

using a 1-7/16 inch hex wrench. Torque all nuts to an initial 217 NSm (160 lbfSft), then a final torque of 434 NSm (320 lbfSft). Follow the bolting procedure described in figure 6.

Troubleshooting

Table 2. Troubleshooting

Problem Possible Solution

Verify the correct packing load. Use gap gage to verify correct gap distances.

Packing Leakage

Bottom Flange Gasket Leakage

Excessive Ball Seal Leakage

Other Consult your Emerson Local Business Partner.

Disassemble and inspect packing box bore and drive shaft for graphite adhesion, excessive wear or scratches.

If needed, increase packing load to maximum per the Packing Adjustment section of this manual. Replace

packing parts and inspect packing box and shaft at next available maintenance interval.

Verify proper torque on bottom flange studs and nuts.

Disassemble and inspect sealing surfaces on the bottom flange and valve body for scratches or nicks.

Verify the Vee-Ball is positioned correctly in the closed position. Reference the Determining Closed Position

section of this instruction manual.

Disassemble and inspect Vee-Ball, sleeve seal, and piston ring for excessive wear or scratches.

Actuator Mounting

The actuator is right-hand mounted in a push-down-to-open (PDTO) configuration.

1. Tighten the bolted joints on this valve/actuator assembly using the criss-cross pattern shown in figure 6. Tighten

each bolt evenly and in the sequence described.

2. Coat the twelve 5/8-11 x 2.75 actuator mounting studs (key 4) with nuclear grade anti-seize lubricant.

3. Mount the actuator onto the valve body (key 1).

4. Install washers (key 146) and tighten the 5/8-11 hex nuts (key 117) to 163 NSm (120 lbSft).

After attaching the actuator to the valve, refer to the Fisher 1052PSV Size 60 Rotary Actuator Instruction Manual, D103407X012, to connect the lever to the drive shaft.

Determining Closed Position

This instruction manual assumes the bottom flange (key 5) has not been attached to the valve body. If the bottom flange is already attached, refer to the 1052PSV instruction manual.

The Vee-Ball is visually positioned into the sleeve seal in this instruction manual. Final closed position will be set using the Precise Valve/Actuator Close Position section of the 1052PSV instruction manual.

Parts Ordering

A serial number is assigned to each valve and stamped on the nameplate. Always refer to the valve serial number when corresponding with your Emerson Process Management sales office regarding spare parts or technical information. When ordering replacement parts, also specify the complete 11‐character part number from the parts kits or parts list information.

WARNING

Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Process Management should not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the performance of the valve, and could cause personal injury and property damage.
