Failure Symptoms

The first sign of a failing relief valve might be a persistent high-pitched whine from the hydraulic pump or a noticeable increase in hydraulic oil temperature. If the valve sticks open, the system will not build adequate pressure, resulting in a significant loss of hydraulic power and function. If it sticks closed, the system is at risk of over-pressurization, potentially damaging pumps, cylinders, or hoses.

Installation Tip

Ensure the hydraulic system is properly depressurized before removing the old valve to prevent injury and fluid loss. Clean the valve mounting port thoroughly to remove any debris before installing the new valve.

Service Note

Inspect the hydraulic filter and oil condition for signs of contamination when replacing the relief valve.
