• The piston is fitted with seals and operates in a ‘honed’ steel cylinder, delivering smooth travel and minimising hysteresis and wear.
• 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.
