Fisher 8580 Rotary Valve - Emerson Electric

Product Bulletin8580 Valve51.6:8580May 2021D103299X012Fisher 8580 Rotary ValveThe Fisher 8580 rotary valve offers excellent throttlingand automated on-off, quarter-turn performance. Anapproximately linear flow characteristic providesprecise throttling control. The 8580 valve offers highcycle life and rugged reliability.The valve body meets PN 10 through PN 40, CL150,and CL300 ratings. Face-to-face dimensions meet EN558, API 609, and MSS-SP68 standards. Line centeringclips provide for versatility to mount and align thesame wafer style valve body in different pipingconfigurations (ASME and EN ratings).The 8580 rotary valve features an eccentricallymounted disk with either soft or metal seal, providingcapability for enhanced shutoff. The interchangeablesealing technology allows for the same valve body toaccept both soft and metal seals.W9498-3LUGGED STYLE(NPS 3 through NPS 12)8580 FeaturesnApproximately linear flow characteristic -- Anapproximately linear flow characteristic providesprecise throttling control.nGlobal Standards -- The valve is based on API, ASME,and EN standards, making it suitable for use in allworld areas. An optional mounting bracket providesISO 5211 actuator mounting capability.nPEEK/PTFE bearing as standard -- The PTFE-linedPEEK bearing is a low friction, low wear bearing. Itallows the valve to operate under high pressuredrops for a high cycle life while maintaining lowtorque. The “drop-in” bearing design enables fast,easy maintenance.nSpline-ended Shaft -- The splined shaft withclamped lever and single-pivot linkage reduces lostmotion between the actuator and the valve shaft.www.Fisher.comX1426nDOUBLE FLANGED STYLE(NPS 3 through NPS 12)Application Versatility -- Optional square shaft isideal for on/off applications and allows actuatorselection flexibility. Standard construction materialsand seal assemblies provide long life and superiorperformance in a broad range of liquid and gasapplications.

Product Bulletin8580 Valve51.6:8580May 2021nExcellent Shutoff -- Both the metal and soft sealrings have pressure-assisting sealing action thatensures tight shutoff regardless of pressure drop.nImproved 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.nnNew 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 anyinstallation.Excellent Emissions Capabilities -- The optionalENVIRO-SEALt packing systems, are designed withvery smooth shaft surfaces and live-loading toprovide improved sealing, guiding, and loadingforce transmission. The seal of the ENVIRO-SEALsystem can control emissions to below 100 ppm(parts per million).nSour Service Capability -- Trim and bolting materialsare available for applications involving sour liquidsand gases. These constructions comply with NACEMR0175-2002, MR0103, and MR0175 / ISO 15156.nField-Reversible Valve Action -- The actuator/valveassembly action can be converted frompush-down-to-open to push-down-to-close, or viceversa, without additional parts.D103299X012nEasy Installation -- Line-centering clips engage theline flange bolts to simplify installation and providefor centering of wafer-style valves in the pipeline.End connections are compatible with EN and ASMEstandards.nLong 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. See figure 2.nReliable Flange Gasketing Surface -- The sealretainer screws and retention clips are outside thegasket surface of the seal retainer. Spiral-wound orflat-sheet gaskets can be installed between theuninterrupted seal retainer face and the pipelineflange.nIntegral Shaft-to-Valve Body Bonding -- Standardvalve construction includes conductive packing toprovide electrical bonding for hazardous areaapplications.nPowder paint as standard -- The Emerson powderpaint finish offers an excellent corrosion-resistantfinish to all steel parts.nHigh Temperature Capability -- The valve willoperate at elevated temperatures, with theappropriate trim components.nShaft 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 1).nTravel 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 Contents8580 Features . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 128580 Valve Specifications andMaterials of Construction . . . . . . . . . . . . . . . . . . . . 3
