GT pneumatic actuator is the most commonly used as a pneumatic actuator, pneumatic actuator market, pneumatic actuators share should be greater than 80% of the pneumatic actuator characteristics is cheap, small size, light weight, the market retains large flexible movement. As long as the gas source to the valves open and close, safe and reliable. 

 GT pneumatic actuator design features 

 A unique bi-directional stroke adjustment; 

 2, a compact dual-piston gear type structure, meshing is accurate, stable output torque; 

 Extruded aluminum alloy, the cylinder is the hard anodizing treatment, the surface texture of hard, wear resistant; 

 4, piston with mechanical Road and O-rings and bearings, to avoid non-metallic and metal contact to reduce the friction coefficient; 

 5, connecting dimensions according to international standards ISO521-DIN3337-VDI/VDE3845 that curtain, can be interchangeable with the vast majority of ordinary pneumatic actuator; 

 6, double acting and single acting (spring return) type using the same themes and cover; 

 7, all moving parts are bearing wear-resistant materials; 

 For stomatal NAMUR standard or with the adapter plate NAMUR standard. With plate solenoid valve can be installed directly; 

 9, the unique position indicator; 

 10, the GT pneumatic actuator according to the needs for support to install the solenoid valve, reply, locators (opening direction), triple pieces and hand-operating institutions.
