Fisher� Control-Disk� Rotary ValveThe Fisher Control-Disk rotary valve (figure 1) offersexcellent throttling performance. An equalpercentage flow characteristic provides an improvedthrottling range comparable to that of a segmentedball valve. This improved capability allows you tocontrol closer to the target set point, regardless ofprocess disturbances, which results in a reduction inprocess variability.
The valve body meets PN 10 through PN 40, CL150,and CL300 ratings. Face-to-face dimensions meetEN 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).
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 metalseals.
The actuator sizing and selection process isimproved by simply reading a table for information.
Control-Disk Valve Features� Equal percentage flow characteristic— An
equal percentage 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 variability.
� Global Standards— The valve meets API,ASME, and EN standards, making it suitable for usein all world areas.
� PEEK/PTFE bearing as standard— ThePTFE-lined PEEK bearing is a low friction, low wearbearing. It allows the valve to operate under highpressure drops for a high cycle life while maintaininglow torque. The “drop-in” bearing design enablesfast, easy maintenance.
� Lower Operating Torques— The equalpercentage disk reduces operating torque at peakangles of disk opening.
� Spline-ended Shaft— The splined shaft withclamped lever and single-pivot linkage reduces lostmotion between the actuator and the valve shaft.
� Improved shaft-disk pinning— The improvedexpansion pin system ensures there is a positive,durable connection between disk and shaft. Thisconnection reduces backlash and wear in the drivesystem, optimizing long-term performance. It alsomakes disassembly for maintenance quick andsimple with no need for special tools.
� 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 no detrimentto performance or cycle life. This complements theability to mount the actuator on the left- or right-handside, enabling access for any installation.
� Excellent Emissions Capabilities— Theoptional ENVIRO-SEAL� packing systems, aredesigned with very smooth shaft surfaces andlive-loading to provide improved sealing, guiding,and loading force transmission. The seal of theENVIRO-SEAL system can control emissions tobelow 100 ppm (parts per million).
� Sour Service Capability— Trim and boltingmaterials are available for applications involving sourliquids and gases. These constructions comply with
NACE MR0175-2002, MR0103, and MR0175 / ISO15156.
� Field-Reversible Valve Action— Theactuator/valve assembly action can be convertedfrom push-down-to-open to push-down-to-close, orvice versa, without additional parts.
� Easy Installation— Line-centering clipsengage the line flange bolts to simplify installationand provide for centering of wafer-style valves in thepipeline. End connections are compatible with ENand ASME standards.
� Excellent Shutoff Regardless of PressureDrop— Both the S31600 (316 stainless steel) sealring and bidirectional PTFE seal ring withpressure-assisting sealing action ensure shutoffregardless of flow direction.
� Long Seal Life— The opening and closingpath of the eccentric disk minimizes disk contact withthe seal ring, thereby reducing seal wear, unduefriction, and seating torque requirements. See figure 3.
� Reliable Flange Gasketing Surface— Theseal retainer screws and retention clips are outsidethe gasket surface of the seal retainer. Spiral-woundor flat-sheet gaskets can be installed between theuninterrupted seal retainer face and the pipelineflange.
� Integral Shaft-to-Valve Body Bonding—Standard valve construction includes conductivepacking to provide electrical bonding for hazardousarea applications.
� Powder paint as standard— The EmersonProcess Management� powder paint finish offers anexcellent corrosion-resistant finish to all steel parts.
� High Temperature Capability— The valve willoperate at elevated temperatures, with theappropriate trim components.
� Shaft Retention— Redundant shaft retentionprovides added protection. The packing follower,anti-blowout ring, and shaft groove interact to holdthe shaft securely in the valve body (see figure 2).
� Travel Indication— Additional travel indicationcan be achieved by using the indication line on theshaft, along with the disk position markings on thepacking follower (see figure 5).

2052 Actuator Features
� Compact design, smaller actuators—Ensures reduced valve/actuator envelopedimensions leading to greater mounting versatility forboth skids and process plants, where space is at apremium.
� Compatible with DVC2000, DVC6200, andDVC6000 digital valve controllers; and 3610J and3620J positioners— The new actuator allowslinkage-less feedback, via a contact-less magneticarray, from the lever to the end-mounted DVC2000.Integral window mounting of the DVC6200,DVC6000, 3610J, and 3620J is also available.
� Clamped lever to reduce lost motion— Theclamping of the lever onto a splined valve shaft,coupled with the single pivot linkage, reduces lostmotion between the actuator and the valve. Thetypical cumulative deadband for a Fisher rotarycontrol valve assembly results in 0.5% or lessvariability.
� No bench set required— The new nestedspring design requires no bench set. This alsosimplifies the actuator selection process, see bulletin61.1:2052, D103295X012.
� ISO 5211 mounting with optional insert—The actuator can now be mounted directly ontonon-spline shafts, such as Square and Double D.This allows the actuator, with its enhanced control,to mount on a wider range of valves conforming toISO 5211.
� Adjustable travel stops standard withoptional lockout feature— Provides the ability toadjust or change the travel range without removingthe actuator or the addition of extra parts. Theoptional lockout feature locks the lever in thespring-fail position.
� Fail-safe mechanism contains noaluminum— All parts in the fail-safe mechanism(made of steel, cast iron, and ductile iron) ensure theactuator will maintain safety integrity in the event ofa fire.
� Powder paint as standard— The EmersonProcess Management powder paint finish offers anexcellent corrosion-resistant finish to all externalsteel and cast iron parts.
� NAMUR VDE/VDI 3845 for accessorymounting— Meeting the global standard ensurescompatibility for most accessories, enabling quickand easy mounting.
� Field reversible, right- or left-handmounting— The actuator/valve assembly action canbe converted from push-down-to-open topush-down-to-close, or vice-versa, without additionalparts.
� Declutchable and top-mountedhandwheels— Available (except top-mounted notavailable for size 3 actuator).
OptionsTop-Mounted Handwheel: For infrequent use as amanual actuator (see bulletin 61.1:2052,D103295X012). For repeated or daily manualoperation, the unit should be equipped with adeclutchable handwheel actuator.
Declutchable Handwheel Actuator: Anend-mounted manual actuator can be used toprovide on-site control and to provide overridecapabilities. See bulletin 61.8:1078 for handwheelactuator specifications.
Limit Switches: � Micro-Switch or NAMCOswitches for one or two single-pole, double-throwcontacts, or � GO proximity switches for one or twosingle-pole, double-throw contacts are available. Seeseparate bulletins for limit switch information.
Position Indicating Switch: TopWorx� DXPM21GNEB switch for one through six single pole,double throw switch contacts are available. Seeseparate bulletin for position indicating switchinformation.
Positioner: For precise positioning of the valvecontrol element, the actuator should be equippedwith a positioner. For additional information, contactyour Emerson Process Management sales officewith complete service conditions.
Actuator Locking Mechanism: An actuator lockingmechanism is available, which can be used to keepthe actuator in a locked position (the same as thespring-fail position) during maintenance. The padlockis customer supplied.
