Pneumatic flange ball valve electric actuator product line motion and produce a lot of drag angle of rotation. Are driven by the motor deceleration devices, the role of the electrical signal is changed by a power on the basis of the basic structure, if we add some additional components can now answer form, with new features. Electric actuators are generally divided into straight stroke, rotary, multi-turn three. Frank Wenzhou Valve Co., Ltd.
