Flowserve Automax Supernova Pneumatic Rack and Pinion Actuator

The Flowserve Automax Supernova Pneumatic Rack and Pinion Actuator is the latest development of the product, which has won worldwide praise for its reliability, versatility and safety. Rugged, yet compact construction combined with new technical solutions make this product extremely reliable & Adaptable in the severest of operating conditions.


The rotational movement of a rack and pinion actuator is accomplished via linear motion and two gears. A circular gear, referred to a “pinion” engages the teeth of a linear gear “bar” referred to as the “rack”.

Pneumatic actuators use pistons that are attached to the rack. As air or spring power is applied the to pistons, the rack is “pushed” inward or “pulled” outward. This linear movement is transferred to the rotary pinion gear (in both directions) providing bi-directional rotation.

rack and pinion

Rack and pinion actuators pistons can be pressurized with air, gas, or oil to provide the linear the movement that spins the pinion gear. To rotate the pinion gear in the opposite direction, the air, gas, or oil must be redirected to the other sides of the piston, or use coil springs as the energy source for rotation. Rack and pinion actuators using springs are referred to as “spring-return actuators”. Actuators that rely on opposite side pressurization of the rack are referred to as “direct acting”.

Most actuators are designed for 100-degree travel with clockwise and counterclockwise travel adjustment for open and closed positions. World standard ISO mounting pad is standard to the Automax SuperNova Actuator to provide ease and flexibility in direct valve installation.

NAMUR mounting dimensions on actuator pneumatic port connections and on actuator accessory holes and drive shaft are also common design features to the Automax SuperNova Actuator to make adding pilot valves and accessories more convenient.
