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).
