Description
Fisher 644 and 645 actuators are used in combination with any of several sliding‐stem valves to automatically control steam‐driven boiler feedwater pumps (reciprocating or turbine). The 644 or 645 actuator, when used in combination with one of several push‐down‐to‐close sliding‐stem valves, forms a pump governor. 644 and 645 actuators may also be combined with push‐down‐to‐open valves to be used as relief governors. Relief governors are used to divert excess pump discharge back to the suction side of the pump.
