Fisher® 3025
Fisher® 3025 Size P460-200, P462 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 as either direct, e.g. air-to-close, or reverse acting e.g. air-to-open. These actuators are designed to provide dependable on-off or throttling operation of automatic control valves.
