3. Common Swing Relief Valve Failure Troubleshooting

• Fault 1: Excavator Swing Weak, Rotary Speed Abnormal
  Cause: Spool wear, internal impurity clogging, spring fatigue deformation.
  Solution: Install new swing relief valve, clean hydraulic oil circuit and replace filter element.
• Fault 2: Swing Circuit Over‑pressure, Swing Motor Damage Risk
  Cause: Valve core stuck, swing pressure‑control function failure.
  Solution: Fit EC360 No‑OEM‑EC360 swing relief valve, calibrate swing loop pressure to standard value after assembly.
• Fault 3: Obvious Hydraulic Noise & Vibration When Rotating
  Cause: Internal parts abrasion, unstable overflow pressure.
  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.
