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 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.

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 with process media rests solely with the purchaser and end‐user. Since some valve body/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.

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

WARNING

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.

1. If the valve is to be stored before installation, protect the 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 will be necessary during

inspection and maintenance of the valve.

3. Mounting the Actuator:

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

factory makes actuator/valve adjustments before the valve is shipped.

b. 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 of this manual.

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

surfaces.

5. Be sure the mating line flanges are aligned. Provide standard flat sheet flange gaskets (or spiral wound gaskets with

compression‐controlling centering rings) that are compatible with the process fluid.

Refer to figure 2 for required clearance for valve installation and stud length. Lubricate the studs with anti-seize

lubricant.

6. Install the valve using studs and nuts to connect the valve flanges to the pipeline flanges. The seal protector ring

(key 3) end of the valve requires longer line flange studs than standard (see figure 2).

Do not attempt to use standard‐length line flange studs for the seal protector end of the valve. Refer to figure 2 for

length of flange studs required.

Install all remaining studs. Tighten the nuts in a criss‐cross sequence to ensure the flange gaskets are properly loaded.

WARNING

The valve drive shaft is not necessarily grounded to the pipeline when installed. Personal injury or property damage could

result if the process fluid or the atmosphere around the valve is flammable, 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.

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 rings. 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 and figure 4).

7. For hazardous applications, attach the optional bonding strap assembly (key 131, figure 4) to the valve drive shaft

(key 6) with the clamp (key 130, figure 4) and connect the other end of the bonding strap assembly to the valve

body with the cap screw (key 23).

8. 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 need 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.

If the valve has ENVIRO‐SEAL live‐loaded packing installed, this initial re‐adjustment will probably not be required.

Refer to the ENVIRO‐SEAL Packing System for Rotary Valves instruction manual (D101643X012) for packing

instructions.

Maintenance

Valve parts are subject to normal wear and must be inspected and/or replaced as necessary. The frequency of

inspection and replacement depends upon the severity of service conditions.

WARNING

The Vee‐ball closes with a cutting motion. To avoid personal injury, keep hands, tools, and other objects away from the 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. Make 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 Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

D The valve packing area 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.

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 are shown in figure 10, unless otherwise indicated. A detailed view of the packing is also shown in figure

If the valve is equipped with the ENVIRO‐SEAL Packing System, refer to the ENVIRO‐SEAL Packing System for Rotary

Valves instruction manual (D101643X012).

Note

For the ENVIRO‐SEAL Packing System, refer to the Parts List section for individual parts (see figure 3). Refer to the ENVIRO‐SEAL

Packing System for Rotary Valves instruction manual (D101643X012) for maintenance instructions.

Stopping Leakage

For PTFE V‐ring packing, leakage around the packing follower and packing flange (keys 17 and 40) can be stopped by

tightening the packing follower nuts (key 20).

If the packing is relatively new and tight on the drive shaft (key 6), and if tightening the packing follower nuts 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, scratches, or corrosion on

the packing box wall.

If the leakage cannot be stopped by the above steps, the packing must be removed and replaced. Inspect the drive

shaft and packing box before installing new packing parts.

Packing Replacement

When replacing the packing, the actuator should not be removed from the valve while the valve is still in the pipeline

or between flanges. Valve/actuator adjustments must be made with the valve out of the pipeline.

Disassembly

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve, 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 work on the equipment.

2. Remove line bolting, remove the control valve from the pipeline, and place the actuator/valve assembly on a

protected flat surface with the seal protector ring facing up.

3. Remove the actuator cover. Note the orientation of the actuator with respect to the valve body and the lever

orientation with respect to the valve drive shaft (see figure 8).

WARNING

When the actuator is removed from the valve, the ball/shaft assembly may suddenly rotate, resulting in personal injury. To

avoid injury, carefully rotate the ball to the 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 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 damage the ball, seal, and valve.

Note

Some actuator designs have a bolt inserted in the lever to spread the clamp on the valve spline shaft. Tightening the bolt expands

the splined lever connection allowing the valve shaft to be removed.

4. When removing the lever (do not loosen the actuator turnbuckle adjustment), remove the actuator mounting

screws and nuts (keys 23 and 24), and remove the actuator. (If necessary, refer to the actuator instruction manual

for assistance.)

Instruction Manual

D101957X012

V150 and V300 Valves

February 2011

5. If necessary, remove the bonding strap assembly before attempting to remove the packing (see figure 4).

6. Remove the packing flange and nuts and packing follower (keys 20, 40, and 17).

If the valve is equipped with the ENVIRO‐SEAL packing system, refer to the ENVIRO‐SEAL Packing System for Rotary

Valves instruction manual (D101643X012) for disassembly.

7. Remove the packing parts (key 16 packing set includes additional key numbers) by making a formed wire hook with

a sharp end. Pierce the rings with the sharp end of the hook in order to remove them. Do not scratch the drive shaft

or packing box wall; scratching these surfaces could cause leakage. Clean all accessible metal parts and surfaces to

remove particles that would prevent the packing from sealing. (Note: Metal packing parts are not provided in the

packing set).

Assembly

If the valve is equipped with the ENVIRO‐SEAL packing system, refer to the ENVIRO‐SEAL Packing System Rotary Valves

instruction manual (D101643X012) for assembly.

1. Install the new packing parts using the parts sequence shown in figure 3.

2. Insert the packing follower and packing flange (keys 17 and 40) and secure them with the packing follower nuts

(key 20). Tighten the nuts far enough to stop leakage during operating conditions.

Note

If the valve is equipped with a bonding strap assembly (figure 4), re‐install the assembly.

3. Reconnect the actuator and lever in accordance with the orientations that were noted in step 3 of the disassembly

procedures. If necessary, use figure 8 to identify the correct index marks.

4. If necessary, refer to the appropriate actuator instruction manual to complete actuator assembly and adjustment.

5. When the control valve is in operation, check the packing follower for leakage and retighten the packing follower

nuts (key 20) as necessary.

Ball Seal Replacement

Perform this procedure if the control 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 on the valve during the ball seal inspection and replacement procedures. Ball seal

assembly details (with key numbers) are also shown in figure 5. Upon inspection, if it is found that the ball, drive shaft,

or bearings need to be replaced, use this procedure to remove the ball seal. Then, proceed to the Bearing and Ball

Maintenance procedures to replace the ball, bearings, or shafts. Then return to this procedure and begin with the

assembly steps in the Ball Seal Replacement section.

During disassembly and re‐assembly procedures, handle the seal protector ring, seal, and other parts (keys 3, 11, 13,

and 37) carefully to prevent damage. A new gasket (key 15) is required whenever the seal protector ring (key 3) is

removed.

CAUTION

Due to the Vee‐ball shape, take care to never rotate either the front skirted edge of the ball or the circular back edge of the

ball through the ball seal at any time. The seal could be damaged.

The flow ring construction does not use a seal (key 11), radial seal (key 37), or wave spring (key 13). Use this procedure

to remove the seal protector ring for flow ring constructions, but disregard any instructions calling for the seal and

other seal parts.

Disassembly

WARNING

If the actuator is removed from the valve, the ball/shaft assembly may suddenly rotate, resulting in personal injury. To avoid

injury, carefully rotate the ball to the stable position after the actuator is removed. If necessary, lock the ball in a specific

position when directed by the following steps.

Key numbers are shown in figure 10, unless otherwise indicated.

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

media from both sides of the valve. If using a power actuator, also shut off all pressure lines to the power actuator

and release all pressure from the actuator.

2. Remove line bolting, remove the control valve/actuator assembly from the pipeline, and place the valve on a

protected flat surface with the seal protector ring facing up. Carefully rotate the ball to the open position.

Note

Lifting bolt holes are provided in the seal retainer or flow ring to assist in its removal from the valve body.

3. Remove the retainer screws (key 21). Carefully remove the seal protector ring and gasket (keys 3 and 15). (For flow

ring constructions, go to step 4.)

a. For valves with composition seal, remove the seal (key 11) from the valve body (key 1).

b. For valves with HD metal seal, once the protector ring has been removed from the valve, push the metal seal

(key 11) out of the seal protector ring (key 3). Remove the radial seal (key 37). Inspect, clean, or obtain

replacement parts as necessary.

Instruction Manual

D101957X012

It might be necessary to remove the HD metal seal by carefully tapping it with a soft punch and hammer. Take care

not to damage the seal protector ring surfaces.

4. Inspect, clean, or obtain replacement parts as necessary. Inspect the gasket and sealing surfaces on the valve body

(key 1), ball (key 2), ball seal (key 11), and seal protector ring (key 3) for damage.

5. If a replacement ball, drive and follower shafts, or bearings (keys 2, 6, 9, and 10) are needed, proceed to the Bearing

and Ball Maintenance procedure for disassembly and assembly procedures. If only the seal is to be replaced,

proceed to the assembly procedure below.

Assembly

Refer to figure 5 for part and key number locations during seal installation.

1. Thoroughly clean all parts that are to be re‐used or obtain replacement parts. Be sure that all sealing surfaces are in

good condition without scratches or wear. If the valve has been installed between line flanges and the flange studs

and nuts have been tightened, always replace the gasket (key 15).

If you have not already done so, lift the valve and place it with the outlet flange face flat on the protected working

surface. Use the lever from the actuator, or provide some other safe method to rotate the ball into the closed position.

The inlet flange face should be up, and the ball approximately centered within the opening.

2. Make sure the ball cannot rotate during seal assembly procedures (read the Warning on page 9).

3. For valves with composition ball seals:

D Install the composition seal (key 11) into the valve body.

D Install the gasket (key 15) on the valve body.
