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
through24,andPN10andPN16compatible
(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).

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.

Features (continued)
Improved Environmental Capabilities–The optional
ENVIRO-SEALt packing systems, shown in figure 6,
are designed with very smooth stem surfaces, and
live loading provides improved sealing, guiding, and
loading force transmission. The seal of the
ENVIRO-SEAL system can control emissions to
below the EPA (Environmental Protection Agency)
limit of 100 ppm (parts per million) for valves.
Lost Motion Minimized–For 8510, the taper pin/disc
connection and the splined valve shaft with
clamped lever and single pivot linkage reduce lost
motion between the actuator and valve. For 8510B,
the taper key/disc connection and the splined valve
shaft with clamped lever and single pivot linkage
reduce lost motion between the actuator and valve.
Greater Capacities and Lower Operating
Torques–The contoured disc increases flow
capacity and reduces operating torque at peak
angles of disc opening.

Construction Features
Field-Reversible Valve Action–The actuator/valve
assembly action can be converted from
push-down-to-open to push-down-to-close, or vice
versa, without additional parts.
Integral Shaft-to-Body Bonding–Standard valve
construction includes conductive packing to
provide electrical bonding for hazardous area
applications.
Easy Installation–Centering holes (figures 1, 2 and
3) engage the line flange bolts to simplify
installation and provide for centering of the valve in
the pipeline.
Long Seal Life–The opening and closing path of the
eccentric disc (figure 4) minimizes disc contact with
the seal ring, thereby reducing seal wear, undue
friction, and seating torque requirements.
Exceptional Shutoff at High Pressure Drops–Both
the 316 stainless steel seal ring and the bidirectional
PTFE seal ring with pressure-assisting sealing action
(figure 5) are designed to provide shutoff regardless
of flow direction.
Reliable Flange Gasketing Surface–The seal retainer
cap screws or retention clips are outside the gasket
surface of the seal retainer, and spiral wound or flat
sheet gaskets can be installed between the
uninterrupted seal retainer face and the pipeline
flange.
Self-Flushing Action–With standard right-hand
actuator mounting, the bottom edge of the disc
opens downstream away from the seal, and the flow
stream flushes sediment from the seal.
Double D Shaft–8510B valves in NPS 2 through 12
are available with double D shaft end designedto
accept the 1035 Rack and Pinion Actuator and other
quarter-turn actuators.
Shaft Retention–Redundant shaft protection is
provided with 8510B valves with the double D drive
shaft. The packing follower and stepped shaft
interact to provide the redundant shaft retention.
