Installation

Separate installation steps are provided in this section for V150 and V300 flanged valves, V200 flangeless valves. Key

numbers in installation procedures are shown in figures 24, 25, and 26 unless otherwise indicated.

Some types of ceramic trim, including VTC, can create a spark under certain conditions. If an edge of a ceramic part is

struck against a second ceramic part with enough force, it can produce a spark.

Instruction Manual

D101554X012

Vee-Ball Valves

March 2021

WARNING

Avoid personal injury and property damage from ignition of process fluid caused by sparks from ceramic trim. Do not use

ceramic trim where the process fluid is unstable or if it is an explosive mixture (such as ether and air).

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.

1. For the flanged V200, the same bolt lengths are used for both the inlet and outlet flange ends because the studs for threaded flange holes are double nutted. If the Cavitrol Hex

anti-cavitation trim is installed, the required outlet flange bolt length will be ½” longer than the Dimension specified in the table above. See Vee-Ball bulletin (D101363X012).

2. For V150 and V300 valve assemblies with the Cavitrol Hex anti-cavitation trim installed, the same bolt lengths are used for both the inlet and outlet flange ends.

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

Attach the optional bonding strap assembly (key 131, figure 3) to the valve drive shaft (key 6) with the clamp (key 130,

figure 3) and connect the other end of the bonding strap assembly to the valve body with the cap screw (key 23).

1. If the valve is to be stored before installation, protect the flange mating surfaces and keep the valve body 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. 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.

4. Standard flow direction is with the seal protector ring (key 3) facing upstream.

5. Install the valve in a horizontal or vertical pipeline with the drive shaft in a horizontal position.

CAUTION

To maximize seal life, the valve should be installed so the drive shaft will be in the horizontal orientation while in service.

Please contact your Emerson sales office for evaluating vertical drive shaft installations.

6. The actuator can be right‐ or left‐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.

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

surfaces.

8. Be sure the pipeline flanges are in line with each other.

Installing V150, V300, and Flanged V200 Valves

1. Install the V150 and V300 valve using studs (keys 32 and 33, not shown) 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 (key 32) than

standard. Do not use standard‐length line flange studs for the seal protector ring end of the valve. The seal

protector ring end of the valve for the DN25/NPS 1 constructions will have threaded flange holes due to insufficient

nut clearance.

2. See table 3 and figure 2 for length of studs for the seal protector ring end of V150 and V300 valves. Lubricate the

studs with anti‐seize lubricant.

3. Insert flat‐sheet line flange gaskets (or spiral‐wound gaskets with compression‐controlling center rings) that are

compatible with the flowing media.

4. 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.

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

ENVIRO‐SEAL Packing System for Rotary Valves instruction manual (D101643X012) for packing instructions.

Installing V200 Valves

Stud length dimensions are shown in figure 4 for the seal protector ring end of the valve. For V200, CL600, the

dimension from the center line of the valve bore to the mounting flange face is larger than a CL150 or 300 valve.

1. Install the V200 valve using long studs (key 32, figure 4) to connect the two pipeline flanges. Refer to figure 4 for

the size of studs required. Lubricate the studs with anti‐seize lubricant.

2. Install two studs in the flanges before you place the valve in the line. Place the two studs so they will contact the

line‐centering notches at the bottom of the valve body.

3. Insert flat‐sheet line flange gaskets (or spiral‐wound gaskets with compression‐controlling center rings) that are

compatible with the process fluid.

4. Place the valve on the two studs. Install all remaining studs. Measure carefully to be sure the valve is centered on the

pipeline flanges, and tighten the flange stud nuts. Tighten the nuts in a criss‐cross sequence to be sure the flange

gaskets are properly torqued.

5. 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.

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 figures 24, 25, and 26, 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, 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 in this procedure are shown in figures 24, 25, and 26, unless otherwise noted. A detailed view of the

packing is also shown in figure 5.

Instruction Manual

D101554X012

Vee-Ball Valves

March 2021

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

D the separate ENVIRO‐SEAL Packing System for Rotary Valves instruction manual (D101643X012) for maintenance

instructions, and

D the Parts List section of this manual for retrofit kits, parts kits, and individual parts.

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 or scratches on the packing

box wall. Inspect the drive shaft and packing box wall for nicks or scratches while performing the following procedure.

Replacing Packing

When using this procedure, it is recommended that the actuator 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. Refer

to the Determining Closed Position portion of the Actuator Mounting section.

Disassembly

WARNING

Observe the steps in the WARNING at the beginning of the Maintenance section.

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, 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.

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

surface with the seal protector ring facing up.

3. Remove the actuator cover. Take note of the orientation of the actuator with respect to the valve body and the

lever orientation with respect to the valve drive shaft (see figure 6).

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.

4. Remove the clamped 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

D101554X012

Vee-Ball Valves

March 2021

5. If applicable, remove the bonding strap assembly before attempting to remove the packing (see figure 3).

6. Remove the packing follower nuts and packing follower (keys 17 and 20). For alloy packing constructions, the

packing follower (key 17) and a separate packing flange (key 40) must be removed if present.

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.

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.

7. Remove the packing parts (see figure 5, keys 16, 17, 35, and 39 depending on construction) using 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.

Assembly

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 assembly.

Series B only

1. For NPS 8, 10, and 12 valves, install the packing spacer (key 34) if it has been removed.

2. To help ensure correct centering of the Vee‐ball (key 2) on the seal (key 11), make sure the ball is closed while you

install or tighten new packing. Insert a screwdriver, pry bar, or similar tool between the lower ear of the ball and the

valve body. Use the pry to move the ball tightly against the bearing on the actuator side of the valve (see figure 6).

Keep the ball in that position until you have completed packing installation and adjustment.

3. Install the new packing parts using the parts sequence shown in figure 5. Install the packing follower (key 17). Alloy

constructions have a packing follower (key 17) and a separate packing flange (key 40) that must be replaced.

4. Secure the packing follower with the packing follower nuts (key 20). Tighten the nuts far enough to stop leakage

under operating conditions.

Handle the seal protector ring, seal, and other parts carefully to prevent damage. A new gasket (key 15) is required

whenever the seal protector ring (key 3) (figure 11) is removed.

Flow ring construction does not use a seal, shims, or spring seal. Use this procedure to remove the seal protector ring

from flow ring constructions, but disregard any instructions calling for the seal, shims, or spring seal.

Note

If the valve is equipped with a bonding strap assembly (figure 3), re‐install the assembly.

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

procedures. If necessary, use figure 23 to identify the correct index marks.

6. Refer to the appropriate actuator instruction manual to complete actuator assembly and adjustment.

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

nuts (key 20) as necessary.
