Working principle and function of proportional pilot solenoid valve

Working principle: Based on the principle of electromagnetic switch valve, electromagnetic force is generated when the electromagnetic coil is energized, overcoming the spring force to move the valve core, opening the valve to allow the pilot oil to pass. Unlike ordinary solenoid valves, it can accurately control the displacement of the valve core by changing the coil current. The coil current is balanced with the electromagnetic force and the spring force, so that the valve opening is linearly related to the coil current, thereby accurately controlling the flow and pressure of the pilot oil.

Function

- Precisely control the action of the actuator: Precisely control the flow direction and flow of hydraulic oil to achieve precise action of the excavator's boom, arm, bucket and other actuators, such as fine adjustment of digging depth, angle, etc.

- Achieve stepless adjustment of action: The speed and force of the actuator can be continuously adjusted within a certain range to avoid sudden changes in action, making excavation, loading and unloading operations smoother and more efficient
