Description
The Fisher 3025 size P460, P462, P460-200 and P900 spring-opposed diaphragm actuators position the valve plug in
the valve body in response to varying controller or valve positioner pneumatic output signals applied to the actuator
diaphragm. They can be specified either direct (air-to-close) or reverse acting (air-to-open). The size P460 offers 65
mm maximum actuator travel. The sizes P462 and P900 provide 120 mm maximum actuator travel. The size
P460-200 offers 203 mm maximum actuator travel. The 3025 actuator can be equipped with a side-mounted
assembly. It is usually used as an auxiliary manual actuator.
