Designed without linkages and with minimal working parts, this actuator offers built-in reliability and low maintenance costs. Series C actuators are always operated through a valve positioner, with two types available to suit different applications.
 
The frequency response of this piston actuator is extremely high, and is superior to comparable diaphragm units. Its linear response to a signal change is unaffected by increasing or decreasing pressure, with sensitivity being maintained over the working range.
