or Local Business Partner before

Description

The Control‐Disk rotary valve offers excellent throttling performance. An equal percentage flow characteristic provides an improved throttling range comparable to that of a segmented ball valve. This improved capability allows you to control closer to the target set point, regardless of process disturbances, which results in a reduction in process variability.

Retainer clips provide for versatility to mount and align the same wafer style valve body in different piping configurations (ASME and EN ratings). The valve body is compatible with PN 10 through PN 40, CL150, and CL300 ratings. Face‐to‐face dimensions meet EN 558, API 609, and MSS‐SP68 standards.

The Control‐Disk rotary valve features an eccentrically‐mounted disk with either soft or metal seal, providing capability for enhanced shutoff. The interchangeable sealing technology allows for the same valve body to accept both soft and metal seals.

Installation

Key numbers in this procedure are shown in figure 10 unless otherwise indicated.

WARNING

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

To avoid personal injury or property damage resulting from the bursting of pressure retaining parts, be certain the service conditions do not exceed either the valve body rating or the flange joint rating, or other limits given in table 1 or on the nameplate. Use pressure‐relieving or pressure‐limiting devices to prevent the service conditions from exceeding these limits.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section on page 7 in this manual.

CAUTION

The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions specified in the customer's order. Because some valve body/trim material combinations are limited in their pressure drop and temperature range capabilities, do not apply any other conditions to the valve without first contacting your Emerson sales office

or Local Business Partner.

The maximum allowable inlet pressures for steel and stainless steel valve bodies are consistent with the pressure‐temperature ratings shown in table 1, except where further limited by the trim and packing material temperature capabilities given in table 3. Valves are also available in CW2M and M35‐2 valve body materials. The CW2M valve body material is not listed in EN 12516-1 or in ASME B16.34. The M35-2 valve body material is listed in ASME B16.34, but is not listed in EN 12516-1. Valve bodies constructed of these materials mate with EN and ASME flanges, but must not be installed in systems requiring conformance to EN or ASME standards if not included in EN or ASME pressure/temperature ratings. Maximum allowable inlet pressures for Control‐Disk valve bodies made of CW2M or M35‐2 construction materials are shown in table 4.

1. Install a three‐valve bypass around the control valve assembly if continuous operation is necessary during inspection and maintenance of the valve.

2. Inspect the valve body to be certain it is free of foreign material.

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

If the valve body and actuator have been purchased separately or if the actuator has been removed for maintenance, mount the actuator, and adjust actuator travel before inserting the valve body into the line. This is necessary due to the measurements that must be made during the actuator adjustment process. Refer to the Actuator Mounting section on page 18 of this manual and to the separate actuator instruction manual for mounting and adjusting instructions before proceeding.

4. Inspect adjacent pipelines to be certain they are free of any foreign material, such as pipe scale or welding slag, that could damage the valve body seating surfaces.

CAUTION

Damage to the disk (key 3) will occur if any pipe flanges or piping connected to the valve body interfere with the disk rotation path. However, the disk can be rotated without interference when the valve body is installed between adjacent pipe flanges or piping that has an inside diameter equal to or greater than either schedule 80 pipe or compatible EN pipe

Instruction Manual

D103298X012

sizes. If piping with a smaller inner diameter than specified above is connected to the valve, measure carefully to be certain the disk rotates without interference before putting the valve into operation.

Control-Disk Valve

June 2017

5. Flow is in the standard direction when the seal retainer (key 2) is facing upstream. Standard flow direction is also indicated by the flow direction arrow cast into the valve body. Flow in the reverse direction is permissible within allowable pressure drop limits for the soft seal. The metal seal is forward flow only.

CAUTION

Control‐Disk valve disk rotation is counterclockwise to open (when viewed from the actuator side of the valve body, see figure 7) through 90 degrees of disk rotation. Rotating the disk (key 3) past either the open or closed position could damage the seal and disk sealing surfaces and could cause the disk to jam in the seal retainer.

6. With the disk in the closed position, install line flange gaskets, and insert the valve between the pipeline flanges. Use either flat sheet gaskets or spiral‐wound gaskets with compression‐controlling centering rings. Spiral‐wound gaskets without compression‐controlling centering rings are not recommended for this purpose.

7. Depending on valve size and pressure rating, the wafer style valve is centered in the pipeline using either retainer clips or the flange bolt holes. (For valves that have four flange bolt holes in the valve body (key 1), each hole engages one corresponding line flange stud.) Insert the valve between the flanges and use either the retainer clips or install two or more line flange studs into the line flanges to help hold the valve in position while centering the valve. Carefully center the valve on the flanges to ensure disk clearance.

D Select and install two pipeline gaskets.

Note

Lubricate line flange studs before inserting them into flanges. If necessary, provide additional support for the control valve assembly because of its combined weight.

WARNING

For lugged valve bodies with threaded line bolt holes, personal injury and property damage could result from sudden release of process pressure if line bolts are not properly installed. To ensure proper line bolt thread engagement, line studs must be centered in the threaded section of the valve body so that each stud has equal thread engagement in the body. See figure 2.

8. After centering the valve body, first lubricate and then install the remaining line flange bolting to secure the valve in the pipeline. Tighten the nuts to the line flange studs in a crisscross pattern to ensure proper alignment of valve, gaskets, and flanges.

WARNING

A Control‐Disk valve body is not necessarily grounded when installed in a pipeline. If the valve is used in a flammable or hazardous atmosphere or for oxygen service, an explosion could result due to a discharge of static electricity from the valve components. To avoid personal injury or property damage, always make sure the valve body is grounded to the pipeline before putting the control valve assembly into operation in a flammable or hazardous atmosphere.

Note

Standard packings for the Control‐Disk valve are composed of all conductive packing rings (graphite ribbon packing) or partially conductive packing rings (such as a carbon‐filled PTFE female adaptor with PTFE V‐ring packing) to electrically bond the shaft to the valve body for hazardous area service. For oxygen service applications, provide alternate shaft‐to‐valve body bonding according to the following step.

Control-Disk Valve

June 2017

9. For oxygen service applications, attach the bonding strap assembly (key 131, figure 3) to the shaft 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 35). Secure each cap screw with a hex nut (key 36).

WARNING

Personal injury could result from packing leakage. Valve packing was tightened prior to shipment; however, the packing might require some re-adjustment to meet specific service conditions.

Valves with ENVIRO‐SEALt packing systems will not require this initial re‐adjustment. See ENVIRO‐SEAL Packing System for Rotary Valves Instruction Manual (D101643X012 present packing arrangement to ENVIRO‐SEAL packing, refer to the retrofit kits listed in the parts kit sub‐section on page 20 of this manual.

) for packing instructions. If you wish to convert your

Maintenance

Valve body parts are subject to normal wear and must be inspected regularly and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions. Instructions are given in this section for: replacing trim components, changing disk rotation or valve action, and mounting and adjusting the actuator.

As used in these instructions, actuator refers to power actuators (such as pneumatic diaphragm, piston actuators, and rack and pinion actuators).

WARNING

Avoid personal injury and property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations:

D Do not remove the actuator from the valve while the valve is still pressurized. D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations. 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

on 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 spring precompression. D Use lock‐out procedures to be sure the above measures stay in effect while you work on the equipment. D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out when removing the packing hardware or packing rings, or when loosening the packing box pipe plug.

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

media.

Packing Maintenance

Instruction Manual

D103298X012

Refer to figure 4 for available packing configurations. All maintenance operations in this section may be performed with the valve in the line. Packing may be PTFE V‐ring or graphite.

An ENVIRO‐SEAL packing system is also available with the Control‐Disk valve. To install the ENVIRO‐SEAL packing system in an existing valve, follow the instructions in the instruction manual included with the packing system (D101643X012). To remove packing parts in a valve with the ENVIRO‐SEAL packing system, follow the procedures for valves with the ENVIRO‐SEAL packing system in this section. Install the replacement packing following the instructions in the packing system instruction manual (D101643X012

Stopping Leakage

For valves with PTFE or graphite packing:

CAUTION

Tighten the packing flange only enough to prevent shaft leakage. Excessive tightening will only accelerate wear of the packing and could produce higher torques on the valve.

Leakage around the packing followers can be stopped by tightening the packing flange nuts (key 28, figure 10).

If the packing is relatively new and tight on the shaft, and if tightening the packing flange nuts does not stop leakage, the shaft may be worn or nicked so that a seal cannot be made. If the leakage comes from the outside diameter of the packing, the leakage may be caused by nicks or scratches around the packing box wall. Inspect the shaft and packing box wall for nicks and scratches when performing the packing replacement procedures.

For valves with the ENVIRO‐SEAL packing system:

Optimum performance of the ENVIRO‐SEAL packing system is obtained when the Belleville springs are tightened to their “target load.” The target load is the point where the springs are compressed to 85% of their maximum deflection, or nearly flat. Maximum deflection is when the springs are 100% compressed, or completely flat.

Under normal conditions, the packing nuts should not require re‐tightening. However, when servicing, if the springs do not remain at the target load of 85% compression, retighten the packing box nuts according to the following procedure:

1. Tighten the packing flange nuts alternately and evenly, keeping the packing flange parallel with the valve flange

(see figure 4), until the Belleville springs are compressed 100% (or completely flat).

D For PTFE packing, loosen each packing flange nut one half turn (180_ of rotation).

D For Graphite packing, loosen each packing flange nut one quarter turn (90_ of rotation).

The target load of 85% compression has now been reached. If leakage continues, replace the packing components as described in the following procedures.

Replacing the Packing

To replace the packing, the actuator must be removed. Also, the valve should be removed from the pipeline to allow proper readjustment of the disk position.

WARNING

The edges of a rotating disk have a shearing effect that may result in personal injury. To help prevent such injury, stay clear of the disk edges when rotating the disk (key 3).

CAUTION

Damage to the disk (key 3) may occur if the disk is not closed when the valve is being removed from the pipeline. If necessary, apply operating pressure to the actuator temporarily to retain the disk in the closed position while removing the valve from the pipeline.

For valves with PTFE or graphite packing:

Key numbers in this procedure 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 body, and drain the

process media from both sides of the valve. If using a power actuator, also shutoff all pressure lines to the power actuator, release all pressure from the actuator. Use lock‐out procedures to be sure the above measures stay in effect while you work on the equipment.

CAUTION

When removing the actuator in the following step, use a wheel puller to separate the actuator parts from the valve shaft. Do not drive the actuator parts off the valve shaft because this could damage valve trim components.

2. Remove the actuator per instructions in separate actuator instruction manuals, then remove the cap screws and

nuts (keys 35 and 36). Remove the clamp (key 130, figure 3) if the strap (key 131, figure 3) is used.

3. Remove the packing flange nuts and the packing flange (key 26) if used and pull out the packing follower (key 25).

4. Remove the anti‐blowout ring (key 40) from the drive shaft (key 10).

5. Remove the old packing rings (key 24) and, if used, the packing washers (key 31). Carefully avoid scratching the

shaft or packing box wall to avoid damage that could cause leakage around the shaft. Clean all accessible metal parts and surfaces to remove particles that would prevent the packing from sealing.

WARNING

Do not lubricate parts when used in oxygen service, or where the lubrication is incompatible with the process media. Any use of lubricant can lead to the sudden explosion of media due to the oil/oxygen mixture, causing personal injury or property damage.

6. Use the appropriate procedures below for installing packing.

D Install the packing as shown in figure 4.

D With graphite ribbon packing, stack the packing rings and packing washers together, and slide the stack into the

packing box as far as it will go while carefully avoiding trapping air between the rings.

D Install the anti‐blowout ring (key 40) in the groove on the drive shaft (key 10).

D Install the packing follower and, if used, the packing flange.

D Install the packing flange nuts, and tighten them only far enough to stop leakage under normal operating

conditions.

D For oxygen service applications, attach the bonding strap assembly (key 131, figure 3) to the shaft with the clamp

(key 130, figure 3), and connect the other end of the bonding strap assembly to the valve body with a cap screw (key 35). Secure each cap screw with a hex nut (key 36).

7. Mount the actuator and adjust the closed position of the valve, per the Actuator Mounting section on page 18 of

this manual, before returning the valve to service.

8. When placing the control valve into operation, check around the packing follower for leakage; retighten the

packing flange nuts as required according to accepted bolting procedures.

For valves with ENVIRO‐SEAL packing systems:

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, also shutoff all pressure lines to the power actuator, release all pressure from the actuator. Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

CAUTION

When removing the actuator, use a wheel puller to separate the actuator parts from the valve shaft. Do not drive the actuator parts off the valve shaft because this could damage valve trim components.

2. Remove the actuator per instructions in separate actuator instruction manuals, then remove the cap screws and

nuts (keys 35 and 36). Remove the clamp (key 130, figure 3) if the strap (key 131, figure 3) is used.

3. Loosen the two packing hex nuts evenly to remove spring tension, then remove the nuts.

4. Remove the packing flange and spring pack assembly. The spring pack assembly consists of the spring stack and

packing follower. The spring stack is retained on the packing follower by an O‐ring. Remove the anti‐blowout ring (key 40) from the driveshaft (key 10). Remove the anti‐extrusion washer, the packing set, and the packing ring.

CAUTION

The valve shaft surface condition is critical in making and maintaining a good seal. If the valve shaft surface is scratched, nicked, dented, or worn, replace the valve shaft before replacing the packing system.

5. Inspect the existing valve shaft. If necessary, replace the valve shaft as described in the Replacing the Disk, Shafts, or

Bearings section.

6. Install the new packing system components as described in the ENVIRO‐SEAL Packing System for Rotary Valves

Instruction Manual (D101643X012

Control-Disk Valve

June 2017

7. Install the anti‐blowout ring (key 40) onto the drive shaft (key 10) before installing the packing follower.

8. Mount the actuator and adjust the closed position of the valve, per the Actuator Mounting section on page 18 of

this manual, before returning the valve to service.

Instruction Manual

D103298X012

Replacing the Seal Ring Assembly

Perform this procedure only if the control valve is not shutting off properly (that is, leaking downstream). This procedure does not require removing the actuator from the valve body.

Key numbers in this procedure are shown in figure 10 unless otherwise indicated.

1. Isolate the control valve from line pressure, and relieve pressure from the valve body. Shut off and disconnect all

lines from the power actuator.

WARNING

The edges of a rotating disk have a shearing effect that may result in personal injury. To help prevent such injury, stay clear of the disk edges when rotating the disk (key 3).

CAUTION

2. Unscrew the flange bolts, and remove the valve from the pipeline.

3. Unscrew the machine screws (key 14), remove the retainer clip (key 13), and remove the seal retainer (key 2).

4. Remove the seal ring assembly (key 4).

5. The valve must be closed during seal ring installation to permit accurate centering of the seal. To install the new

seal ring assembly:

D For a soft seal, if the spring (key 5) was disassembled, hook the spring ends together. Work the spring into the

recess in the seal ring (key 4). Place the seal ring assembly onto the disk. Set the retainer onto the seal, making sure proper alignment between the seal and retainer has been achieved.

D For the metal seal ring assembly, place the seal ring assembly onto the disk. Set the retainer onto the seal, making

sure proper alignment between the seal and retainer has been achieved.

6. Attach the seal retainer (key 2) and the retainer clips (key 13) to the valve body and secure with the machine screws

(key 14).

CAUTION

To avoid possible product damage, ensure the bearing tabs are oriented correctly when installing in the following procedure. See figure 5 for proper orientation of the bearings.

1. If new bearings (key 6) are required, install and orient them in the valve body, as shown in figure 5. Ensure the

bearings are fully seated, contacting the inside diameter of the valve body.

2. Insert the disk into the valve body as shown in figure 6, ensuring the “T” stamped on the disk hub is oriented toward

the actuator end of the valve body.

3. Install the drive shaft (key 10) through the valve body into the disk. The disk/shaft connection utilizes taper and

expansion pins. The hole for the drive shaft connection is slightly off‐center to prevent the drive shaft from being installed in the wrong orientation. Orient the position indication mark on the end of the shaft with the face of the disk as shown in figure 7. For valves using a two-piece, split-shaft, the hole for the follower shaft connection is on‐center. Insert the expansion pins into the disk until they are seated, as shown in figure 6. Once in place, insert the taper pins. The taper pins must be driven into the disk/shaft/expansion pin assemblies until “solid contact” is felt. “Solid contact” can be identified by the sound of the hammer blow and the bounce felt in the hammer. NPS 8-12 valves changed to a one-piece, through-shaft design in 2015 and utilize only one pin connection. NPS 8-12 valves shipped prior to 2015 used a two-piece, split-shaft design with two pin connections - same as the NPS 2-6 valves.

4. Reinstall the follower spring/spring seat assembly (keys 9, 12, and 9, figure 8) inside the follower shaft or follower

side of the drive shaft for valves with a one-piece, through-shaft design.

5. Install the spacer (key 15) if used, and the gasket, blind flange, and hex nuts (keys 16, 17, and 19). Ensure the blind

flange is oriented so the serrations face the gasket and valve body. Tighten the hex nuts (key 19) per table 7.

6. The valve must be closed during seal ring installation to permit accurate centering of the seal. To install the new

seal ring assembly or flow ring:

D For a soft seal, if the spring (key 5) was disassembled, hook the spring ends together. Work the spring into the

recess in the seal ring (key 4). Place the seal ring assembly onto the disk. Set the retainer onto the seal, making sure proper alignment between the seal and retainer has been achieved.

D For the metal seal ring assembly, place the seal ring assembly onto the disk. Set the retainer onto the seal.

D For the flow ring construction, place the gasket (key 41) onto the valve body. Set the retainer onto the gasket.

7. Attach the seal retainer (key 2) and the retainer clips (key 13) to the valve body and secure with the machine screws

(key 14).

8. Insert a packing box ring (key 23) into the packing box.

9. For standard packing, install the packing according to the appropriate instructions presented in step 5 of the

Replacing Packing section on page 11 of this manual. For ENVIRO‐SEAL packing, install the new packing system components as described in the ENVIRO‐SEAL Packing System for Rotary Valves Instruction Manual (D101643X012).

10. Install the anti‐blowout ring (key 40) in the groove in the drive shaft.

11. Rotate the disk to the approximate closed position.

12. Mount and adjust the actuator per the following Actuator Mounting section on page 18 of this manual.

Actuator Mounting

With the valve body out of the line, mount the actuator on the valve body in accordance with the instructions in the actuator instruction manual. Mount the actuator yoke to the valve body, and tighten the actuator‐mounting cap screws and nuts (keys 35 and 36) to the appropriate torque from table 8.

Key numbers in this procedure are shown in figure 10 unless otherwise indicated.

1. Determine the actuator mounting style and position from figure 9.

CAUTION

Control‐Disk valve disk rotation is counterclockwise to open (when viewed from the actuator side of the valve body, see figure 7). Rotating the disk (key 3) past the fully closed position will damage the seal ring (key 4). To prevent this damage, use the following procedures:

D For actuators with adjustable travel stops, such as a Fisher 2052, 1051/1052 size 33, 1066 or 1066SR actuator, make

certain the actuator travel stop prevents the disk from rotating past the fully closed position.

D For actuators with an adjustable turnbuckle, such as the Fisher 1051/1052 size 40, 60, and 70, or 1061 actuator, the

turnbuckle must be adjusted so that the valve is closed when the diaphragm plate or piston is against the actuator travel stop.

2. Adjust the actuator to bring the disk to the fully closed position at the end of the actuator stroke. To determine the

fully closed disk position, measure the distances between the disk face and the seal retainer face at the top and bottom of the valve (X1 and X2) as shown in figure 7. Adjust the travel stops or turnbuckle to rotate the disk slightly until the two measurements are within 0.8 mm (0.032 inch) of each other. Refer to the appropriate actuator instruction manual for assistance.

Parts Ordering

When corresponding with your Emerson sales office or Local Business Partner about this equipment, always mention the valve serial number.

WARNING

Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions 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.
