Double acting pneumatic actuator for 90° operation for On-Off and Modulating heavy duty service
Features & Benefits:
- 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
- An extensive range of accessories is available:
- limit switch boxes - explosionproof, intrinsically safe and/or weatherproof
- limit switches can be provided in different types according to customer requirements
