FPWM2412339 — Relief Valve 823012520 For Volvo Excavator Ec290 Ec460 Ec290B

This is a high-pressure relief valve designed to protect the hydraulic system from over-pressurization by diverting excess fluid back to the tank. It is manufactured to precise specifications, ensuring accurate pressure regulation and reliable operation, unlike a worn or sticking valve. Operators may notice erratic hydraulic movements, a sudden loss of hydraulic power, or excessive heat in the hydraulic system when this valve fails.

Failure Symptoms

The first symptom of a failing relief valve is often inconsistent hydraulic performance, where functions may suddenly become sluggish or lose power. If the valve sticks open, hydraulic pressure will be lost, leading to a complete inability to perform work; if it sticks closed, the system can over-pressurize. Over-pressurization can cause hoses to burst or pumps to be severely damaged.

Installation Tip

Ensure the hydraulic system is depressurized before attempting to remove or install the relief valve. Clean the valve seat thoroughly to ensure a proper seal and prevent leaks.

Service Note

Inspect the hydraulic system for contamination and check the hydraulic pump output pressure when replacing a relief valve.
