VP0050SRK10 Pneumatic Butterfly Valve Actuator is suitable for rotary valves with a double-piston rack and pinion structure, featuring precise meshing, 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 source port, top of the output shaft, and mounting holes at the top adhere to the NAMUR standard. The same specifications are available in double-acting and single-acting (spring return) versions, with the option to choose the rotation direction—clockwise or counterclockwise—based on valve requirements. Electromagnetic valves, positioners, limit switches, and manual operation devices can be installed according to user needs.
