Introduction

Scope of Manual

This instruction manual includes installation, maintenance, and parts information for the Fisher Control‐Disk valve,

DN50 through DN300 or NPS 2 through NPS 12 (figure 1). Refer to separate instruction manuals for information

covering the power on‐off actuator and accessories.

Do not install, operate, or maintain a Control-Disk 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 sales office or Local Business Partner before

proceeding.

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

Control-Disk Valve

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.

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.

Control-Disk Valve

June 2017

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.

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‐SEALtpacking systems will not require this initial re‐adjustment. See ENVIRO‐SEAL Packing

System for Rotary Valves Instruction Manual (D101643X012) for packing instructions. If you wish to convert your

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.

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.

Figure 3. Optional Shaft‐to‐Valve Body Bonding Strap Assembly

Packing Maintenance

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.

Control-Disk Valve

June 2017

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.
