• Specification

• Functions

1.Overpressure Protection: The core function of these relief valves is to prevent excessive pressure buildup in the hydraulic system. When the pressure in the system exceeds the preset pressure value of the relief valve, the valve will open, allowing the hydraulic fluid to flow back to the reservoir, thus reducing the pressure in the system and protecting components such as hydraulic cylinders, pipelines, and pumps from damage caused by overpressure.

2.System Stability Maintenance: By regulating the pressure, the relief valves ensure that the hydraulic system operates within a safe pressure range, which helps to maintain the stability and reliability of the system. This is crucial for the normal operation of construction machinery, as it can prevent performance degradation or malfunctions of the equipment caused by pressure fluctuations.
