Fisher 655 and 655R Diaphragm Actuators
Fisher 655 and 655R actuators provide control for a wide variety of pressure regulation applications. The 655 actuator is used for pressure reduction service on push-down-to-close valves, and the 655R actuator is primarily for pressure relief use on push-down-to-open valves. These actuators may be either self-operated or remote-loaded.
- Spring of the proper rate is available for nearly any control valve application. Spring selection procedure is quick and accurate.
- Direct-operated configuration provides faster speed of response.
