Pneumatic Actuators
Series 79 Stainless Steel
Series 79P stainless steel pneumatic actuators have a 316 stainless steel housing for chemical resistance and high strength. The actuator functions using a double piston rack and pinion arrangement for a smooth torque profile throughout the actuator stroke. Air-to-spring models feature pre-loaded springs that safely avoid potential hazards during maintenance. The base of the actuator has an ISO output drive and bolt circle for easy mounting to quarter turn valves. The top of the actuator has a visual position indicator and a NAMUR mounting pad to accommodate mounting accessories. The air ports are 1/4″ NPT and have a NAMUR bolt pattern to accommodate flush mount solenoids.
