Fisher Control-Disk Rotary Valve - Emerson

1 Control-Disk Rotary ValveThe Fisher Control-Disk Rotary Valve offers excellentthrottling performance. An equal percentage flowcharacteristic provides an improved throttling rangecomparable to that of a segmented ball Valve . Thisimproved capability allows you to control closer to thetarget set point, regardless of process disturbances,which results in a reduction in process Valve body meets PN 10 through PN 40, CL150,and CL300 ratings. Face-to-face dimensions meet EN 558, API 609, and MSS-SP68 standards. Linecentering clips provide for versatility to mount andalign the same wafer style Valve body in differentpiping configurations (ASME and EN ratings).

2 The Control-Disk Rotary Valve features aneccentrically-mounted disk with either soft or metalseal, providing capability for enhanced shutoff. Theinterchangeable sealing technology allows for thesame Valve body to accept both soft and metal ValveFeaturesn Equal percentage flow characteristic An equalpercentage flow characteristic provides animproved throttling range comparable to that of asegmented ball Valve . This improved capabilityallows you to control closer to the target set point,regardless of process disturbances, which results ina reduction in process Global Standards The Valve meets API, ASME, andEN standards, making it suitable for use in all PEEK/PTFE bearing as standard The PTFE-linedPEEK bearing is a low friction, low wear bearing.

3 Itallows the Valve to operate under high pressuredrops for a high cycle life while maintaining lowtorque. The drop-in bearing design enables fast,easy FLANGED STYLE(NPS 3 through NPS 12)X1426W9418-2 LUGGED STYLE(NPS 3 through NPS 12)n Lower Operating Torques The equal percentagedisk reduces operating torque at peak angles of Spline-ended shaft The splined shaft with clampedlever and single-pivot linkage reduces lost motionbetween the actuator and the Valve ValveD103297X012 Product : control -DiskJuly 2018 Control-Disk ValveD103297X012 Product : control -DiskJuly 2018 2n Improved shaft - disk pinning The improvedexpansion pin system ensures there is a positive,durable connection between disk and shaft .

4 Thisconnection reduces backlash and wear in the drivesystem, optimizing long-term performance. It alsomakes disassembly for maintenance quick andsimple with no need for special New Spring-Loaded shaft The spring in theoutboard shaft provides support to the drive trainand disk , enabling the shaft to be installed in bothhorizontal and vertical orientations with nodetriment to performance or cycle life. Thiscomplements the ability to mount the actuator onthe left- or right-hand side, enabling access for Excellent Emissions Capabilities The optionalENVIRO-SEALt packing systems, are designed withvery smooth shaft surfaces and live-loading toprovide improved sealing, guiding, and loadingforce transmission.

5 The seal of the ENVIRO-SEAL system can control emissions to below 100 ppm(parts per million).n Sour Service Capability Trim and bolting materialsare available for applications involving sour liquidsand gases. These constructions comply with NACEMR0175-2002, MR0103, and MR0175 / ISO Field-Reversible Valve Action The actuator/valveassembly action can be converted frompush-down-to-open to push-down-to-close, or viceversa, without additional Easy Installation Line-centering clips engage theline flange bolts to simplify installation and providefor centering of wafer-style valves in the connections are compatible with EN and Excellent Shutoff Both the metal and soft sealrings have pressure-assisting sealing action thatensures tight shutoff regardless of pressure Long Seal Life The opening and closing path of theeccentric disk minimizes disk contact with the sealring, thereby reducing seal wear, undue friction,and seating torque requirements.

Spiral-wound orflat-sheet gaskets can be installed between theuninterrupted seal retainer face and the Integral shaft -to- Valve Body Bonding Standardvalve construction includes conductive packing toprovide electrical bonding for hazardous Powder paint as standard The Emerson powderpaint finish offers an excellent corrosion-resistantfinish to all steel High Temperature Capability The Valve willoperate at elevated temperatures, with theappropriate trim shaft Retention Redundant shaft retentionprovides added protection.

7 The packing follower,anti-blowout ring, and shaft groove interact to holdthe shaft securely in the Valve body (see figure 1).n Travel Indication Additional travel indication canbe achieved by using the indication line on theshaft, along with the disk position markings on thepacking follower (see figure 4).Table of ContentsControl- disk Valve Features Valve Specifications and Materials of Construction ValveD103297X012 Product : control -DiskJuly 2018 3 Control-Disk Valve Specifications and Materials ofConstructionTable 1.
