Double acting pneumatic actuator for 90° operation for On-Off and Modulating heavy duty service

Totally enclosed, weatherproof housing in nodular cast iron for maximum strength and suitable for use in hostile environments
A compact rack and pinion design provides simple construction and constant output torque throughout the 90° stroke
An adjustable bronze sliding block supports the transverse force exerted on the rack by its engagement with the pinion
Rack and pinion in nodular cast iron, output shaft in alloy steel for maximum strength
The rack is nitrided for minimal friction
External travel stops for precise angular stroke adjustment between 80° and 100°
Electroless nickel plated and polished cylinder and output shaft for corrosion resistance and minimal friction
Floating type piston seals for low hysteresis and high sensitivity, preventing sticking problems
Lever or jackscrew manual override
