With the development of industrial needs, the bypass solenoid valve for power units appeared later than the pneumatic solenoid valve, but its application range has become increasingly wide. Because it does not require an air source, installation and use are relatively convenient; it only needs to be connected to a power supply and control signal to operate. Below, the Chongqing Refrigerated Truck editor introduces the structure and function of the bypass solenoid valve for power units.

The bypass solenoid valve for power units is an industrial field actuator composed of a solenoid valve body and various electric actuators. It accepts 4-20mA or pulse signals output from the regulator to perform closed-loop control, realizing automatic control of parameters such as flow rate, pressure, temperature, and liquid level. Intelligent electric actuators can be selected, enabling digital transmission with DCS, PLC, etc., to form a more intelligent control system. The power supply voltage for bypass solenoid valves for power units is available in 220V and 380V. The flow characteristics of bypass solenoid valves, electric single-seat solenoid valves, and electric small-flow solenoid valves include equal percentage, linear, and fast flow characteristics.
