Product Overview
The VALBIA 82DA0007 / DA32 is a double-acting pneumatic rotary actuator engineered for precise quarter-turn (90°) operation of industrial process valves, including ball, butterfly, and plug valves. Manufactured by VALBIA, a recognized specialist in pneumatic and hydraulic actuation technology, this rack-and-pinion actuator converts compressed air pressure into controlled rotary torque through a precision-machined piston and gear rack mechanism. The DA32 series is designed for reliable on/off and modulating service within automated process control loops, delivering consistent torque output and rapid response for demanding industrial valve automation applications.
