AW系列气动执行器

AW系列气动执行器分为双作用式和单作用式（弹簧复位），两个气体分缸，输出扭矩大，动作灵活平衡；活塞杆镀硬铬，有很好的耐磨性；所有滑动部件之间配有无油润滑轴和导向环以降低摩擦系数，延长使用寿命AW气动执行器的U型曲线特性输出扭矩更适用于大口径球阀、蝶阀等转角行程阀门的启、闭和调节，也可用于其它回转运动的场合，是实现工业管道自动化控制的理想装置。

AW Series pneumatic actuators are divided into double-acting and single acting （spring return）, two sub-cylinder gas, the output torque, balanced and flexible movement; hard chromium plated piston rod, good wear resistance; all sliding between parts with or without oil lubrication shaft and guide ring to reduce friction and prolong the life of AW pneumatic actuator output torque characteristic U-shaped curve is more suitable for large-diameter ball valve, butterfly valve stroke corner Kai, closed and regulation, can also be used for other rotary movement of the occasion, is to achieve the ideal of industrial automation control device pipeline.

型号选择Model selection
    选用AW气动执行器时，先确定阀门启、闭的扭矩，再根本阀门使用的流体介质，增加安全值。对清洁、润滑介质增加20%
安全值；对水蒸汽或非润滑介质增加25%安全值；非润滑的干气介质增加60%安全值；非润滑气体输送的颗粒粉料介质增加
100%安全值。然后根据气源工作压力，查找双作用式或单作用式输出扭矩表，可得到准确的执行器信号。单作用式输出扭矩
表中，zui小弹簧扭矩即为关闭阀门时的扭矩，zui大弹簧扭矩即为打开阀门时的扭矩。

AW pneumatic actuator used, make sure the valve opens, closing torque, and then do the valve using a fluid medium, added security value. For cleaning, lubricating medium increased by 20%
Security value; of water vapor and non-lubricating medium security value by 25%; non-lubricated dry gas media to increase 60% security value; non-lubricated gas transmission medium to increase the powder particles
100% security value. Then the gas supply pressure of work, find the double-action or single-acting output torque table, available and accurate actuator signal. Single-acting torque
Table, the minimum time to close the valve spring torque is the torque, maximum torque is to open the valve spring torque.
