• Specifiion

• Function

1.Overpressure Protection: It is the primary function of the relief valve. When the pressure in the hydraulic system exceeds the set value of the relief valve, the valve will automatically open, allowing the excess hydraulic oil to flow back to the oil tank, thus preventing the system pressure from being too high and protecting hydraulic components and pipelines from being damaged by high pressure.

2.Pressure Stabilization: The relief valve can maintain the system pressure within a certain range. In the throttling adjustment system of the fixed - displacement pump, it can ensure the stability of the pump outlet pressure, avoiding the impact of pressure fluctuations on the equipment and ensuring the stable operation of the equipment.

3.System Unloading: In some circuits, by connecting a small - flow solenoid valve in series with the remote - control port of the relief valve, when the solenoid valve is energized, the remote - control port of the relief valve is connected to the oil tank, and the hydraulic pump unloads, achieving energy - saving operation.
