3. Common Main Relief Valve Failure Troubleshooting

• Fault 1: Low Working Pressure & Weak Action
  Cause: Internal spool jam, spring fatigue or sealing surface wear.
  Solution: Install brand‑new main relief valve, clean hydraulic oil and replace filter element.
• Fault 2: Hydraulic System Over‑pressure
  Cause: Valve core stuck closed, pressure adjustment failure.
  Solution: Replace complete main relief valve, check pump output pressure condition.
• Fault 3: Valve Internal Oil Leakage & Abnormal Noise
  Cause: Sealing surface abrasion and hydraulic oil impurity pollution.
  Solution: Fit new relief valve, clean the whole hydraulic oil circuit.
• Fault 4: Unstable Pressure Fluctuation
  Cause: Spring deformation, spool movement blocked.
  Solution: Replace complete main relief valve and calibrate system pressure.
