6700RA 气动活塞式执行机构(角行程)
基本介绍

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。与角行程调节阀组合使用,可用于调节和开关的场合,也可用于其它回转运动的场合。

该系列采用拨叉机构与导向杆组合的结构设计,使输出扭矩更稳定。底部与阀门连接法兰的尺寸符合 ISO 5211 标准。顶部输出轴符合 NAMUR 标准,便于安装限位开关,定位器等附件。

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

The design of this serie's actuators combines both scotch yoke mechanism and guide rod, which helps the output torque to become more stable. The bottom flange which connects the actuator and the valve body fully meets the standard of ISO 5211. The top output shaft can fully meet the requirements of NAMUR and it's also convenient for the installation of accessories such as limit switch, positioner, etc.
