进口重载型拨叉式气动执行器结构特点 STRUCTURAL FEATURES

1.重载型拨叉式气动执行器通用于一般以90度旋转的阀门。例如∶球阀、蝶阀、旋塞阀等开关或调节流量的功能  Series heavy duty pneumatic Actuators are designed to perform in the most demanding applications. They are engin-eered to automate all types of quarter turn valves(ball, butte-rfly,plug and damper) with multiple torque profiles available for every situation.

2.CTRA系列执行器是对称设计。在0度与90度时输出扭矩。中间位置输出扭矩最小。正对应于球阀类产生的扭矩特性  CTRA series is equipped with a SYMMETRIC design yoke that produces maximum torques at both ends of the stroke (0°and 90°) and minimal in the middle,therefore this series is the optimal solution for metal seated ball valves,plug valves and for modulating service.

3.模块化设计和结构可在安装、维修和储存方面提供便利 Modular design and construction resulting in flexbility and interchangeability.

4.缸体内壁采用镀硬铬工艺，******的使用寿命 Using technology of plating hard chorming, which can ensure longer service life.

5.CTRB系列执行器是采用倾斜设计，可以输出更大的起始扭矩，更符合蝶阀类的扭矩特性 CTRB series is equipped with a CANTED design yoke that produces a higher maximum torque at the beginning of stroke (i.e.valve unseating/reseating at 0°) and less torque at the end of stroke (90°), therefore this series is optimal solution forhigh performance butterfly valves.

6.轨道高频淬火研磨处理，滑块采用方形自润滑工艺，能***长久的使用寿命 Pathway high-frequency quenching grinding treatment ,sliding block using self-lubricating technology, which can ensure permanent usability
