The composition of electric valve
General electric valve consists of the following parts: dedicated motor, characterized by overload capacity is strong, large starting torque, moment of inertia of small, short, intermittent work. Retarding mechanism, in order to reduce the output speed of the motor. Schedule control mechanism, and accurate control to adjust the valve open/close position. Torque limit institutions, to adjust the torque ( Or thrust) And make it less than predetermined value. Manual and electric switching mechanism, manual or electric interlock of the operation. The opening indicator to show the valve's position in the process of opening and closing.
