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.

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 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
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.
6.The actuator can be rightor 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 and V300 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.

2.See table 2 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.

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.
DDisconnect 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.
DUse 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.
DThe 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.
DCheck 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.
If the valve is equipped with the ENVIRO-SEAL Packing System, refer to:
Dthe 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.)
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.
Replacing the Ball Seal
Disassembly
Perform this procedure if the control valve is not shutting off properly or if seal inspection is necessary. If you find upon inspection that the ball, shaft, or bearings need to be replaced, use this procedure to remove the ball seal. Then, proceed to the Bearing and Ball Maintenance procedures. Then, return to this procedure and begin with the assembly of the ball seal steps.
While the actuator/valve assembly must be removed from the pipeline, the actuator may remain mounted on the valve as you replace the ball seal.
Key numbers are shown in figures 24, 25, and 26, unless otherwise indicated. Ball Seal assembly details (with key numbers) are also shown in figures 8, 9 and 10.

WARNING
Perform the steps in the WARNING at the beginning of the Maintenance section of this manual.
1.Remove line bolting, remove the control valve from the pipeline, and place the valve on a flat surface with the seal protector ring facing up. Carefully rotate the ball to the open position.
2.Remove protector ring screws and washers (keys 21 and 22). Carefully remove the seal protector ring and gasket (keys 3 and 15). (For flow ring constructions, go to step 4.)
a.For a Fisher TCM seal, remove the seal (key 11) from the valve body. For NPS 1, 1-1/2, and 2 valves, also remove the backup ring (key 14, figure 8) from the valve body.
b.For a flat metal seal, remove the spring seal, seal, and shims (keys 13, 11, and 12). (Note: It may be necessary to re-use some of the original shims when reassembling the flat metal seal.)
c.For an HD metal seal or a high temperature 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 wave spring (key 13), and on the HD metal seal, the radial seal (key 37).
Note
The high temperature HD metal seal also has a piston ring (key 133) that will need to be removed. It will be in two pieces for the NPS 1, 1-1/2 and 2 valves, and one piece with a break in it for the NPS 3 through 12 valves.
CAUTION
Exercise care to avoid damaging components in the following procedure.

|
|
DIt 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.
DNPS 3 through 12 valves, if the seal is difficult to push out, it is recommended that a seal removal plate be used to press the HD metal seal out of the seal protector ring. Refer to figure 12 for dimensions of the seal removal plate.
DNPS 10 and 12 valves with an attenuator only: Remove the retaining ring (key 41) in the seal protector ring. This retaining ring is an octagonal-shaped support wire. To remove the retaining ring, find one of the free ends of the ring. Use a screwdriver or similar tool to pry inward and upward until the ring is removed.
3.Inspect the gasket and sealing surfaces on the valve body (key 1 or 1A), the seal protector ring (key 3), Vee-ball (key 2), and the retaining ring (key 41 for NPS 10 and 12 valves with an attenuator only). Be sure the sealing surfaces are not damaged.
4.If replacement of the ball, shafts (keys 6 or 9), or bearings (key 10) is needed, proceed to the Bearing and Ball Maintenance procedure. If only the seal is to be replaced, proceed to the Assembly steps below.
Assembly
Refer to figures 8, 9, and 10 for key number locations during seal installation. Valve key number locations are shown in figures 24, 25, and 26.
1.Thoroughly clean all parts that are to be re-used and 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) with a new gasket.
2.To help ensure correct side-to-side centering of the ball (key 2) on the seal (key 11), make sure the ball is closed while you install the seal or flow ring and seal protector ring. Insert a screwdriver, pry bar, or similar tool between the lower ear of the ball and the valve body (see figure 6).
3.Use the pry to move the ball tightly against the bearing on the actuator side of the valve. Be careful, excessive force may damage the ball. Keep the ball in that position until you have completed seal or flow ring installation. Check the ball's position periodically, and re-center if necessary, during lever assembly and packing adjustments.
WARNING
The Vee-Ball closes with a shearing, cutting motion, which could result in personal injury. To avoid injury or property damage, keep hands, tools, and other objects away from the Vee-Ball while stroking the valve.
4. Install the seal.
CAUTION
Due to the Vee-ball shape, take care to never completely rotate either the front skirted edge or the circular back edge of the ball out of the ball seal as the seal could be damaged.

D Install the seal protector ring (key 3) into the valve body. Now go to step 5 in this procedure.
Installing flat metal seals:
a.Install 12 shims in the valve and install the flat metal seal on top of the shims.
b.Install the spring seal (key 13) on the flat metal seal (key 11) with the convex side of the spring seal facing the ball.
c.Install the seal protector ring, and install the protector ring screws and washers (keys 21 and 22). Tighten the screws.
d.Add or remove shims under the ball seal as necessary to obtain zero ball seal deflection as accurately as possible.
Note
Zero ball seal deflection for a flat metal seal is the point at which the addition of one 0.13 mm (0.005 inch) thick shim causes contact between the ball and ball seal to be broken. Hold the parts tightly together when determining zero deflection, or improper zero deflection might result.
e.After zero deflection is reached, remove the seal protector ring, spring seal, seal and 4 shims. Final assembly of the control valve should not exceed a maximum of 9 shims for zero deflection. If more than 9 shims are required, contact your Emerson Process Management sales office.
f.Install the gasket (key 15) on the valve body.
g.Install the seal protector ring (key 3) into the valve body. Now go to step 5 in this procedure.
Installing HD metal seals:
Note
The older and newer designs of the NPS 1 and 1-1/2 seal protector ring are functionally the same, but are different lengths and not interchangeable. All NPS 1 and 1-1/2 sizes of V150 and V300 valves are the newer design. The change in seal protector ring length occurred in the 1992/1993 timeframe and affects NPS 1 and 1-1/2 V200 valves only. To determine whether you have the older or newer design, measure the length of the seal protector ring (key 3, figure 26) from its pipeline flange mating surface to its opposite end. Compare your measurement to those listed in figure 7.
a.For NPS 1 and 1-1/2 valves: The older and newer designs of the NPS 1 and 1-1/2 seal protector rings are functionally the same, but are different lengths and not interchangeable. Refer to figure 7 for protector ring dimensions.
D Install the wave spring (key 13) onto the ball seal.
DLubricate and install the radial seal (key 37) onto the ball seal (key 11). Make sure the open side of the radial seal faces away from the ball.
D Push the ball seal assembly into the seal protector ring (key 3).
D Go to step 5 in this procedure.

b. For all NPS 3 through 8 valves and NPS 10 and 12 valves without attenuator:
DLubricate and install the radial seal (key 37) into the appropriate groove in the seal protector ring making sure the open side of the radial seal faces away from the ball.
D Install the wave spring (key 13) into the seal protector ring (key 3).
DInstall the HD metal seal (key 11) into the seal protector ring (key 3), past the radial seal. While pushing it past the radial seal, make sure the HD metal seal is level. Go to step 5 in this procedure.
c.For NPS 10 and 12 valves with attenuator:
DLubricate the radial seal with lithium grease and install the radial seal (key 37) into the appropriate groove in the seal protector ring making sure the open side of the radial seal faces away from the ball.
D Install the wave spring (key 13) into the seal protector ring (key 3).
DTo install the retaining ring (key 41), find one of the free ends of the ring. Insert the free end into the groove in the seal protector ring. Work around the ring, pressing it into the groove until the ring is completely in its groove.
DInstall the HD metal seal (key 11) into the seal protector ring (key 3), past the radial seal. While pushing it past the radial seal, make sure the HD metal seal is level.
DThe HD metal seal uses a retaining ring (key 41) for NPS 10 and 12 valves only. This retaining ring is an octagonal-shaped support wire. Go to step 5 in this procedure.
Installing high temperature HD metal seals:
a.For NPS 1, 1-1/2 and 2 valves: The older and newer designs of the NPS 1 and 1-1/2 seal protector rings are functionally the same, but are different lengths and not interchangeable. All part numbers in this manual are for the newer design. Refer to figure 7 for ring dimensions.
D Place the wave spring (key 13) on top of the HD metal seal (key 11).
DBreak the piston ring (key 133) into two approximately equal pieces either by placing the ring over a pencil or similar object and applying pressure down-wards on the ring until the ring snaps. Be sure to match the broken ends together as you install it on the HD metal seal (key 11).
DLay the HD metal seal (key 11) down on a flat surface and push the seal protector ring (key 3) into place. Make sure the seal is level. Go to step 5 in this procedure.
b.For NPS 3 through 8 valves:
