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

Initial signs of a failing hydraulic valve include a noticeable lag in hydraulic system response or a slight decrease in system pressure. If left unaddressed, the valve can cause intermittent operation of hydraulic components, leading to reduced equipment efficiency. Continued operation with a faulty valve risks uneven wear on hydraulic actuators and potential system contamination.

Installation Tip

Ensure the hydraulic system is properly depressurized before removing the old valve to prevent fluid loss and injury. Avoid overtightening the valve body, as this can distort the sealing surfaces and cause leaks.

Service Note

Inspect the hydraulic fluid for contamination and check the condition of associated hoses and fittings when replacing this valve.
