3. Common Pump Control Valve Failure Troubleshooting

• Fault 1: Whole Machine Weak Action, Slow Working Speed
  Cause: Spool wear, internal impurity clogging, spring fatigue deformation.
  Solution: Install new pump control valve, clean hydraulic oil circuit and replace filter element.
• Fault 2: Main Pump High Heat, Abnormal Power Consumption
  Cause: Valve core stuck, pressure‑flow control function failure.
  Solution: Fit DH220‑5 No‑OEM‑DH220‑5 pump control valve, calibrate main pump pressure and flow parameter after assembly.
• Fault 3: Abnormal Hydraulic Noise & Vibration During Operation
  Cause: Internal parts abrasion, unstable pressure regulation.
  Solution: Replace complete valve assembly, check hydraulic oil cleanliness status.
• Fault 4: Oil Leakage At Valve Thread Connection Position
  Cause: Sealing ring aging, thread surface scratch damage.
  Solution: Change whole valve or matching seal repair kit.
