A proportional valve is a proportional valve in which the output is proportional to the input signal. It can continuously and proportionally control the pressure, flow and direction of the gas according to the specified input signal. Proportional valves are widely used in applications where control accuracy and dynamic characteristics are not...

The proportional directional valve is based on the electromagnetic force generated by the solenoid coil outside the spool to control the movement of the spool, relying on the control coil current to control the displacement of the spool in the directional valve, so it can control the direction of oil flow and flow at the same time.
