Aluminium Rack & Pinion Actuators

The Actuator

Our Quifer Rack & Pinion pneumatic actuators are specifically designed for use with quarter-turn valves, sporting a wide torque range that ensures our actuators match the operational characteristics of plug, ball or butterfly valves; or any other device requiring precise and reliable 90º rotary motion.

Our pneumatic actuators are constructed of high quality material and undergo 100% pressure, leak and rotation testing before being dispatched.

The Result

An actuator that will remain fully operational under even the most severe service conditions. Our low-cost, high-quality models provide a reliable and cost-effective means of valve operation, ensuring a longer service life and lower overhead costs.
