该系列是一种大输出力、高性能的气动活塞式执行机构，分为双动作型和单动作型两种。与直行程调节阀（单座阀、套筒阀、闸阀）组合使用，可用于调节和开关的场合。该系列也可用于其它直线运动的场合。

This Series provides double-acting and spring return pneumatic cylinder actuators characterized by large output and  high-performance. Combined with linear stem motion type control valves, including globe valves, cage valves, and gate valves, the actuators of this Series are suited for modulating and on-off services. Uses with other linear motion devices are also good.
