The pressure reducing valve of the excavator distribution valve is usually a fixed value pressure reducing valve. The valve core is initially open, the inlet and outlet are connected, and it is controlled by the pressure at the outlet. When the outlet pressure does not reach the set pressure, the valve port is fully open and the valve core does not move. When the outlet pressure reaches or exceeds the set pressure, the valve core moves up and the valve port opening decreases. The resistance at the valve port increases, the pressure drop increases, and the outlet pressure drops and stabilizes at the set value.
- Pressure reduction: Reduce the pressure of a branch oil circuit in the hydraulic system so that the branch pressure is lower than the main oil circuit pressure. For example, in Komatsu excavators, the self-pressure pressure reducing valve can reduce the high-pressure oil output by the main pump to a control pressure of 3.3±0.2MPa, providing a low-pressure control oil circuit for the solenoid valve and PPC valve.
- Pressure stabilization: Keep the outlet pressure stable within the set pressure range. Even if the inlet pressure or flow changes, as long as the outlet pressure reaches the set value, the pressure reducing valve will maintain the outlet pressure stable by adjusting the valve opening, ensuring the stability and reliability of the operation of related hydraulic components.
