Fisher™ 657 and 667 Size 30i - 76i Diaphragm

Actuators
Fisher 657 and 667, size 30i to 76i, spring-opposed
diaphragm actuators position the valve plug in the
valve in response to varying controller or valve
positioner pneumatic output signals applied to the
actuator diaphragm. Zero setting of the actuator is
determined by the compression of the actuator spring,
and span is set by the actuator spring rate. The 657
actuator is direct-acting; the 667 is reverse-acting.
These actuators are designed to provide dependable
on-off or throttling operation of control valves.
