該系列是一種大輸出力、高性能的氣動活塞式執(zhí)行機構(gòu)，分為雙動作型和單動作型兩種。與直行程調(diào)節(jié)閥（單座閥、套筒閥、閘閥）組合使用，可用于調(diào)節(jié)和開關(guān)的場合。該系列也可用于其它直線運動的場合。
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.
