Typical application of proportional solenoid valve

The flow control valve is a proportional solenoid valve. By controlling the flow of the proportional solenoid valve, various controls can be performed. That is, the flow control valve can not only control the flow but also control the pressure, temperature, etc. The typical application of the proportional solenoid valve is as follows . ()
The
Control Actuator (Static Pressure Control)

Two proportional solenoid valves control air for pneumatic actuation (piston valves, cylinders, etc.). The PID controller determines which proportional solenoid valve must be opened. The controller sets the drive signal through the proportional solenoid valve so that the process value matches the given setpoint.

Control the liquid level by pressurization

One method of level control is to control the pressure of the gas above the liquid level. With two proportional solenoid valves, the PID controller can provide enough air (nitrogen in this case) to keep the pressure above the liquid level constant (the gas pressure will drop as the liquid level drops).
