3. Common Auxiliary Relief Valve Failure Troubleshooting

• Fault 1: Auxiliary Hydraulic Circuit Abnormal High‑Pressure
  Cause: Spring fatigue failure, spool clamping stagnation, hydraulic oil mixed with impurities.
  Solution: Install brand‑new auxiliary relief valve, flush hydraulic circuit and replace hydraulic filter element.
• Fault 2: Overflow Noise & Vibration
  Cause: Internal parts wear, foreign debris stuck inside valve body, spring deformation.
  Solution: Replace complete auxiliary relief valve assembly, clean the whole hydraulic oil loop.
• Fault 3: Valve Spool Sticking
  Cause: Metal debris and oil dirt enter valve interior, component deformation.
  Solution: Fit new auxiliary relief valve, thoroughly clean hydraulic tank and oil passages.
• Fault 4: Internal Leakage of Auxiliary Valve Assembly
  Cause: Sealing surface scratch, long‑term high‑pressure impact damage.
  Solution: Replace auxiliary relief valve, inspect wear condition of matched hydraulic pipelines.
