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 (figures 1 and 2). 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 Process Management sales office 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.

Instruction Manual Control-Disk Valve May 2011 D103298X012 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. Figure 2.

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.

Instruction Manual D103298X012 Control-Disk Valve May 2011 WARNING For single flange 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 3. 8.

Control-Disk Valve Instruction Manual May 2011 D103298X012 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.

Instruction Manual Control-Disk Valve D103298X012 May 2011 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. Figure 5.
PAGE 10
Control-Disk Valve May 2011 Instruction Manual D103298X012 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.

Remove the clamp (key 130, figure 4) if the strap (key 131, figure 4) 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 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.

Instruction Manual D103298X012 Control-Disk Valve May 2011 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). 7. Be certain the disk is closed before installing the valve according to the Installation section on page 4 of this manual.
