Fisher 657 and 667 Diaphragm Actuators
The Fisher™ 657 and 667 diaphragm actuators are designed to ensure stable opening/closing or throttling operations of the control valve. These spring-balanced diaphragm actuators respond to the pneumatic output signals from the controller or valve positioner, determining the position of the valve core.
