The ACTREG ACT200R, ADA200, and ASR200 pneumatic actuators from Aichuange are powered by compressed air. They utilize piston rack linear motion to drive the output shaft's gear transmission, providing angular stroke output. Available in double-acting and single-acting types, they are widely suitable for the switching and regulation of angular stroke valves such as ball valves, butterfly valves, and plug valves, as well as other rotary applications. They are ideal devices for achieving automated control in industrial pipelines.

Design Features:
Extruded aluminum (ASTM6005) cylinder body with finely ground inner surface, advanced anti-corrosion technology applied both internally and externally, low cylinder friction coefficient, long service life, and strong corrosion resistance;
Dual-piston rack and pinion design, compact structure, symmetrical installation position, easy change of output shaft direction, long service life, and rapid action;
Composite bearings and guide rings installed on the back of the piston rack, ensuring precise action, low friction coefficient, and extended service life;
Combined pre-loaded coated springs with long working life;
