 Brief Introduction:

Valve box is a unified whole, its implementing agencies are thin film, piston, fork and gear rack. Piston stroke is long, apply to require a greater thrust of the occasion; and thin film-type travel, can only drive the stem directly. Fork type pneumatic actuators with torque, small space, torque curve more in line with the valve torque curve and other characteristics, but not very beautiful; commonly used in high torque valve. The rack and pinion type pneumatic actuators have the advantages of simple structure, smooth and reliable operation, and safe explosion-proof, etc., in the power plant, chemical, oil refining and other high safety requirements of the production process has a wide range of applications.
