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

A malfunctioning cartridge valve can initially cause intermittent issues such as slow or jerky hydraulic movements, or a slight loss of system pressure. If the problem progresses, hydraulic functions may become erratic, unpredictable, or cease to operate altogether, leading to a significant reduction in equipment productivity. Failure to address a faulty valve can lead to overheating of the hydraulic system and potential damage to pumps and cylinders.

Installation Tip

Ensure the hydraulic system is clean and free of debris before installing the new valve to prevent contamination. Always install the valve in the correct orientation as indicated by any markings on the valve body.

Service Note

It is crucial to flush the hydraulic system and replace the hydraulic filter element when replacing a cartridge valve to remove any debris or contaminants.
