• Repair Workshop: Excellent dimensional compatibility, convenient installation, reliable pressure‑release performance.
• Overseas Parts Dealer: Stable stock supply, complete QC inspection records support cross‑border spare‑parts trading.

3. Common Swing Overflow Valve Failure Troubleshooting

• Fault 1: Excavator Swing Weak And Slow Rotation
  Cause: Valve spool wear, internal impurity clogging, spring fatigue deformation.
  Solution: Install new No‑OEM‑PC60‑7‑Swing‑Over‑Flow‑Valve swing overflow valve, clean hydraulic oil circuit and replace filter element.
• Fault 2: Swing Jitter And Impact When Starting‑Stopping Rotation
  Cause: Valve spool jamming, swing loop pressure setting deviation.
  Solution: Fit PC60‑7 No‑OEM‑PC60‑7‑Swing‑Over‑Flow‑Valve swing overflow valve, adjust pressure value according to machine specification after assembly.
• Fault 3: Abnormal Hydraulic Noise During Slewing Operation
  Cause: Internal component abrasion, poor pressure buffering effect.
  Solution: Replace complete valve assembly, inspect hydraulic oil cleanliness condition.
• Fault 4: Hydraulic Oil Leakage At Connection Joint
  Cause: Sealing ring aging, joint surface scratch damage.
  Solution: Replace whole valve unit or matching seal repair kit.
