www.Fisher.com Fisherr 8510 and 8510B Eccentric Disc Control Valves (EMA) Fisher 8510 and 8510B eccentric disc valves feature an eccentrically mounted disc and a PTFE or 316 stainless steel seal ring. The pressure-assisted seal ring provides excellent shutoff against pressure applied in either direction. The 8510B is a multi-class rated valve, available in NPS 2 through 12, and PN10 through PN100 compatible (compatibility varies with size and class, see table 1). The 8510 is rated for CL150, available in NPS 14 through 24, and PN10 and PN16 compatible (compatibility varies with size and class, see table 1). These valves combine with a variety of power and manual actuators to form reliable, high-performance control valves suited for many liquid and gas applications requiring extremely low leakage. Constructions are available for temperatures up to 538C (1000F). Unless otherwise noted, all NACE references are to NACE MR0175-2002. Features Sour Service Capability–Materials are available for applications involving sour service. These materials comply with the requirements of NACE MR0175-2002. Excellent Flow Control–The eccentrically mounted disc design provides an approximately linear flow characteristic and can be used for on/off or throttling control applications through 90 degrees of disc rotation. Optional disc stop on 8510B provides seal protection.

1. The pressure/temperature limits in this bulletin and any applicable standard or code limitation for valve should not be exceeded.2. The Environmental Protection Agency (EPA) has set a limit of 100 parts per million (ppm) for fugitive emissions from a valve.3. For othermaterials of construction, see table 3.4. In vacuum service it is not necessary to reverse the ENVIRO-SEAL PTFE packing rings.
Features (continued) Improved Environmental Capabilities–The optionalENVIRO-SEALt packing systems, shown in figure 6,are designed with very smooth stem surfaces, andlive loading provides improved sealing, guiding, andloading force transmission. The seal of theENVIRO-SEAL system can control emissions tobelow the EPA (Environmental Protection Agency)limit of 100 ppm (parts per million) for valves.
Lost Motion Minimized–For 8510, the taper pin/discconnection and the splined valve shaft withclamped lever and single pivot linkage reduce lostmotion between the actuator and valve. For 8510B,the taper key/disc connection and the splined valveshaft with clamped lever and single pivot linkagereduce lost motion between the actuator and valve.
Greater Capacities and Lower OperatingTorques–The contoured disc increases flowcapacity and reduces operating torque at peakangles of disc opening.

Construction Features Field-Reversible Valve Action–The actuator/valveassembly action can be converted frompush-down-to-open to push-down-to-close, or viceversa, without additional parts.
Integral Shaft-to-Body Bonding–Standard valveconstruction includes conductive packing toprovide electrical bonding for hazardous areaapplications.
Easy Installation–Centering holes (figures 1, 2 and3) engage the line flange bolts to simplifyinstallation and provide for centering of the valve inthe pipeline.
Long Seal Life–The opening and closing path of theeccentric disc (figure 4) minimizes disc contact withthe seal ring, thereby reducing seal wear, unduefriction, and seating torque requirements.
Exceptional Shutoff at High Pressure Drops–Boththe 316 stainless steel seal ring and the bidirectional
PTFE seal ring with pressure-assisting sealing action(figure 5) are designed to provide shutoff regardlessof flow direction.
Reliable Flange Gasketing Surface–The seal retainercap screws or retention clips are outside the gasketsurface of the seal retainer, and spiral wound or flatsheet gaskets can be installed between theuninterrupted seal retainer face and the pipelineflange.
Self-Flushing Action–With standard right-handactuator mounting, the bottom edge of the discopens downstream away from the seal, and the flowstream flushes sediment from the seal.
Double D Shaft–8510B valves in NPS 2 through 12are available with double D shaft end designed toaccept the 1035 Rack and Pinion Actuator and otherquarter-turn actuators.
Shaft Retention–Redundant shaft protection isprovided with 8510B valves with the double D driveshaft. The packing follower and stepped shaftinteract to provide the redundant shaft retention.

Material SelectionGuidelinesPick the valve body, trim, and other constructionmaterials from tables 3, 4, and 5, according to therecommendations and limitations in tables 6, 7, 8, 9,10, and 11. Also, make sure that thepressure/temperature limits in the specifications tableand tables 1, 2, 6, 7, 8, 9, 10, and 11 are not exceeded.
InstallationAs indicated in this bulletin, M35-1 valve bodies are notASME B16.34 or ASME code-approvedmaterials. Valvebodies constructed of M35-1 will mate with ASMEflanges, but are not included in ASMEpressure-temperature ratings andmust not beinstalled in systems requiring conformance to ASMEstandards.
An 8510 and 8510B valvemay be installed in anyposition.
Dimensions are shown in figure 7.
