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
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.

Instruction Manual
D103298X012
Installation
Key numbers in this procedure are shown in figure 11 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 8
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 19 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
4
Instruction Manual
D103298X012
pipe flanges or piping that has an inside diameter equal to or greater than either schedule 80 pipe or compatible EN pipe
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

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 8) 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.
9. For oxygen service applications, attach the bonding strap assembly (key 131, figure 4) to the shaft 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 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

Instruction Manual
D103298X012
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.
