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
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.

Instruction Manual Control-Disk Valve June 2017 D103298X012 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. - Page 5 Instruction Manual Control-Disk Valve D103298X012 June 2017 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.

Page 7: Maintenance
Instruction Manual Control-Disk Valve D103298X012 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. -

All maintenance operations in this section may be performed with the valve in the line. Packing may be PTFE V‐ring or graphite. - Page 9 Instruction Manual Control-Disk Valve D103298X012 June 2017 Figure 4.

- Page 10 Instruction Manual Control-Disk Valve June 2017 D103298X012 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).

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. - Page 13 Instruction Manual Control-Disk Valve D103298X012 June 2017 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 in the following step, use a wheel puller to separate the actuator parts from the valve shaft.
