Rack and pinion actuators are mechanical devices used to automatically open and close valves or dampers, usually for industrial applications. “Rack and pinion” is a generic term for a pair of gears which convert linear motion into rotational motion.

A rack and pinion is a type of linear actuator that comprises a circular gear (the pinion) engaging a linear gear (the rack). [1] Together, they convert between rotational motion and linear motion: rotating the pinion causes the rack to be driven in a line.

2024年9月23日 · Rack and pinion actuators convert rotational motion into linear motion by utilizing a gear mechanism. The rack, a flat bar with teeth, moves linearly, while the pinion, a small gear, rotates. As the pinion turns, its teeth mesh with the rack’s, causing it to move.

2024年9月18日 · Rack-and-pinion pneumatic rotary actuators, also called limited rotation cylinders, are often used for automation of quarter-turn valves, like ball or butterfly valves. They convert compressed air into an oscillating rotary motion.

TRIAC® Stainless Steel Rack and Pinion Actuators offer an economical solution to harsh chemical environments and the corrosion resistant requirements of the pharmaceutical, food, beverage, pulp and paper, and petrochemical industries.

The EL-O-Matic F-series is a rack & pinion actuator, available in 13 sizes as spring return or double acting models. The actuator's “Fit & Forget“ design provides the optimum performance for a wide range of quarter turn valve applications.

A rack-and-pinion type pneumatic rotary actuator is a rotary actuator used for turning, opening, closing, mixing, oscillating, positioning, and many more mechanical functions involving restricted rotation. It is also often used for automation of quarter-turn or half-turn motion mechanisms.

Rack and pinion actuators convert linear movement of a driving mechanism to provide a rotational movement designed to open and close quarter-turn valves such as ball, butterfly, or plug valves and also for operating industrial or commercial dampers.

The R Series is a heavy-duty rack and pinion style rotary actuator that is designed to excel in the most rigid applications. The The R Series includes a high torque-to-size ratio as well as accurate positioning.

The Bettis RPX-series is a rack & pinion actuator, available in 13 sizes as spring return or double acting models. The actuators are designed to automate the most popular quarter turn valves like ball, butterfly and plug valves.
