The precision small valve electric device is a control signal using a motor as a driving source and a hard DC current, and is mainly composed of an operator, an amplifier and an actuator. With this small and small valve electric device, the temperature is basically controlled at about 50 °C.
The actuator consists of two parts: the actuator and the adjustment mechanism (also known as the control valve). The types and configurations of the adjustment mechanisms for various actuators are roughly the same, the main difference being the different actuators. The adjustment mechanism uses a variety of general purpose control valves, which are beneficial for both production and use.
In the selection of valve electric actuator, besides the matching of valve and other components, the control mode of valve electric actuator should also be considered. In the control mode of valve electric actuator, there are two common types of valve electric actuator:
