　　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 heavyduty pneumatic Actuators are designed to perform in the most demandingapplications. They are engin-eered to automate all types of quarter turnvalves(ball, butte-rfly,plug and damper) with multiple torque profilesavailable 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 isequipped with a SYMMETRIC design yoke that produces maximum torques at bothends of the stroke (0°and 90°) and minimal in the middle,therefore thisseries is the optimal solution for metal seated ball valves,plug valves and formodulating 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，保证更长的使用寿命Using technology of plating hard chorming, which can ensure longer servicelife.

　　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 thatproduces a higher maximum torque at the beginning of stroke (i.e.valveunseating/reseating at 0°) and less torque at the end of stroke (90°), therefore thisseries 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，能保证长久的使用寿命 Pathway high-frequency quenching grinding treatment ,sliding blockusing self-lubricating technology, which can ensure permanent usability.
