3. Common PC Valve Failure Troubleshooting

• Fault 1: Excavator Digging Power Insufficient, Whole Machine Output Weak
  Cause: Spool wear, internal contamination blockage, spring fatigue deformation.
  Solution: Install brand‑new No‑OEM‑PC120‑6‑PC‑Valve PC valve, flush hydraulic circuit and replace filter element.
• Fault 2: Excavator Working Action Slow, Joystick Operation Response Delay
  Cause: Spool sticking, internal flow channels blocked by impurities.
  Solution: Fit PC120‑6 No‑OEM‑PC120‑6‑PC‑Valve PC valve, fully clean the complete hydraulic oil loop.
• Fault 3: Hydraulic Pressure Fluctuation, Abnormal Noise From Main Pump
  Cause: Internal component abrasion, pressure‑regulating function failure.
  Solution: Replace complete PC valve assembly, inspect hydraulic oil cleanliness status.
• Fault 4: Hydraulic Oil Leakage At PC Valve Connection Joints
  Cause: Seal ring aging, scratch damage on mating surface.
  Solution: Replace full valve assembly or matching seal repair kit.
