VALBIA DA125 82DA0019 Double-acting Pneumatic Actuator features a dual-piston rack and pinion structure suitable for rotary valves, offering precise engagement, high efficiency, and stable output torque (0-8000 N.m). The cylinder body is made of aluminum alloy or stainless steel. The bottom shaft mounting hole of the pneumatic actuator complies with the ISO5211 standard, while the air supply port, top output shaft, and top mounting holes adhere to the NAMUR standard. The same specifications are available in double-acting and single-acting (spring return) types, with rotation direction selectable as clockwise or counterclockwise based on valve requirements. Solenoid valves, positioners, limit switches, and manual override devices can be installed according to user needs.

VALBIA DA125 82DA0019 Double-acting Pneumatic Actuator is powered by compressed air, utilizing the linear motion of the piston rack to drive the gear transmission of the output shaft, providing angular travel output. Available in both double-acting and single-acting types, it is widely used for the switching and regulation of quarter-turn valves such as ball valves, butterfly valves, and plug valves. It is also suitable for other rotary applications, making it an ideal device for automating industrial pipeline control.
