Rack & Pinion Pneumatic Actuator – DA, SA Series

Rack & Pinion Pneumatic Actuators are compact, high-performance rotary actuators designed to convert compressed air energy into precise 90° rotational motion for valve automation. These actuators are widely used for operating quarter-turn valves such as ball valves, butterfly valves, and plug valves in industrial process systems.

The Rack & Pinion design ensures balanced torque output, smooth operation, and excellent repeatability throughout the stroke. Available in Single Acting (Spring Return – Fail Safe) and Double Acting (Air-to-Open / Air-to-Close – Fail Stayput) configurations, these actuators provide flexibility for both safety-critical and continuous-duty applications.

With rugged construction, corrosion-resistant materials, and ISO/NAMUR standardized interfaces, Rack & Pinion Pneumatic Actuators offer reliable performance, long service life, and easy integration with automation systems
