Introduction:

          Generally, control valve consists of the actuator and the valve body. According to the power used by the actuator, the control valve can be divided into three types: pneumatic control valve, electric control valve, and hydraulic control valve. The control valve has the function of opening、closing and adjusting, and the actuator is composed of the electric motor, oil cylinder or air cylinder, and can realize the reciprocating linear motion or angular motion.

          Firstly, the control valve accepts the control signal, then through the control units like the servo valve, proportional valve, or positioner to control the flow media, and converts the electrical signal into linear or rotary mechanical motion to drive the valve movement.
