Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a faulty relief valve may be a sudden loss of hydraulic system pressure or unexpected jerky movements of actuators. If ignored, the valve could stick open or closed, leading to continuous pressure loss or dangerously high system pressures. Continued operation risks damage to hydraulic components and potential loss of equipment control.

Installation Tip

Ensure the valve seat in the hydraulic block is clean and free of debris before installing the new valve to guarantee a proper seal. Avoid using excessive force when tightening the valve, as this can damage the threads or the valve itself.

Service Note

When replacing a relief valve, inspect the hydraulic pump, filters, and fluid for contamination or signs of wear.
