3. Common LS Relief Valve Failure Troubleshooting

• Fault 1: Excavator Slow Movement, Weak Working Performance
  Cause: Valve spool wear, internal impurity clogging, spring fatigue deformation.
  Solution: Install new No‑OEM‑PC60‑7‑LS‑Valve LS relief valve, clean hydraulic oil circuit and replace filter element.
• Fault 2: High Fuel Consumption, Hydraulic System Pressure Fluctuation
  Cause: Valve spool jamming, load‑sensing pressure setting deviation.
  Solution: Fit PC60‑7 No‑OEM‑PC60‑7‑LS‑Valve LS relief valve, adjust pressure value according to machine specification after assembly.
• Fault 3: Hydraulic Vibration & Abnormal Noise During Operation
  Cause: Internal component abrasion, unstable load‑sensing feedback.
  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.
