Fisher 1B Pump Governor Actuator

The Fisher 1B pump governor actuator is used to maintain a constant discharge pressure on steam-driven turbine or reciprocating pumps and for pressure reducing or pressure relief applications. Typical pump governor applications include fire pumps, boiler feedwater pumps, and industrial or refining pumps where the discharge medium is oil, steam, air, or other non-corrosive fluid. The 1BR type pump governor actuator is combined with a push-down-to-open valve for service as a relief governor.
