This is a kind of actuating mechanism of high performance pneumatic piston, rack and gear transmission. It is a good driving mechanism that can form a complete set with rotary regulating valve (angular travel). Its characteristics include compact structure, high precision, small friction factor, powerful output torque, small volume and convenient installation.

Notes: (1) Spring output torque denotes the spring output torque of actuating mechanism in time of 0¡ãand 90¡ãangular travel under no air pressure.
(2) Different quantity of springs can be placed at two ends of actuating mechanism according to specific needs, for instance, ¡°3+4¡± denotes placing 3 springs at one end and 4 springs at the other end.
