02.新型雙桿導向結構，力矩分配更加合理 unique new dual rod guide structure, torque distribution is more reasonable
03.軌道采用高頻淬火研磨處理，可拆卸設計，維護成本低 orbit is treated by high frequency quenching and grinding, with knock-down design, low maintenance cost.
04.namur標準尺寸，適用指示開關、定位器等配件安裝 the top-works dimensions, both for shaft height and mounting pattern are according to namur standards allowing for easy and standard limit switch、positioner attachment.
05.氣缸內壁鍍硬鉻，以限度地提高耐磨性和耐腐蝕性 the internal wallof the cylinder is hard chrome plated in order to maximize wear and corrosion resistance.
06.寬大方形活靈，大幅提高撥叉組件整體使用壽命 the slide block has a wide surface contact area, thereby increased service life of pneumatic actuator.
07.雙行程調節螺栓，可調節范圍在 ±6°以內 the pneumatic actuators are all provided with bi directional travel stops to allow for open and closed position location adjustments of+/-6 degrees.
08.高強度銅合金+石墨自潤滑功能滑塊，方形防卡死設計卡簧固定方式，保障零部件整體性、安全性和使用壽命high strength copper alloy, sliding block with graphite self lubricating function, square anti jamming design. spring fixed way, to protect the integrity, safety and service life of components.
09.特殊加大的閥軸孔徑設計，可直接安裝較大規格的直徑軸，無需另配聯軸器和支架 special increased valve shaft bore diameter design, can install thicker diameter shaft directly without coupler and bracket.
進口重載型撥叉式氣動執行器結構特點 structural features
1.重載型撥叉式氣動執行器通用于一般以90度旋轉的閥門。例如∶球閥、蝶閥、旋塞閥等開關或調節流量的功能 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系列執行器是對稱設計。在0度與90度時輸出扭矩。中間位置輸出扭矩最小。正對應于球閥類產生的扭矩特性 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.模塊化設計和結構可在安裝、維修和儲存方面提供便利 modular design and construction resulting in flexbility and interchangeability.
4.缸體內壁采用鍍硬鉻工藝，保證更長的使用壽命 using technology of plating hard chorming, which can ensure longer service life.
5.ctrb系列執行器是采用傾斜設計，可以輸出更大的起始扭矩，更符合蝶閥類的扭矩特性 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.軌道高頻淬火研磨處理，滑塊采用方形自潤滑工藝，能保證長久的使用壽命 pathway high-frequency quenching grinding treatment ,sliding block using self-lubricating technology, which can ensure permanent usability.
