AW气动执行器分为双作用式和单作用式（弹簧复位），两个分体气缸，输出扭矩大，动作灵活平衡；活塞杆镀硬铬，有很好的搞磨性；所有滑动部件之间均有无油润滑轴承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。AWpneumaticactuatorhastwotypes,doubleactingandsingleacting(springreset),twodividedcylinder,withlargeoutputtouque,flexibleandbalance.Thepistonrodisplatedwithhardchromiumwithgoodabrasionresistance.Allslidingmembersareequippedwithnonoillubricantbearingandguidingringsiastoreducethefrictioncoefficientandprolingservicelife.TheUcurveouputtorqueofAWpneumaticactuatorshowsthatitismoresuitableforballvalveandbutterflyvalvewithlargecaliber.)
