2. Application Scope

Perfectly matched for PC60‑7 series excavator hydraulic system and engineering machinery overhaul jobs:

• Hydraulic Overhaul: Direct replacement for worn, stuck or pressure‑drifted original unloading valve.
• System Pressure Protection: Unload redundant pressure, lower standby load of hydraulic pump and reduce oil temperature rise.
• Repair Workshop: Excellent dimensional compatibility, convenient installation, reliable unloading performance.
• Overseas Parts Dealer: Stable stock supply, complete QC inspection records support cross‑border spare‑parts trading.

3. Common Unloading Valve Failure Troubleshooting

• Fault 1: High Hydraulic Oil Temperature, Pump Over‑load
  Cause: Valve spool wear, internal impurity clogging, spring fatigue deformation.
  Solution: Install new No‑OEM‑PC60‑7‑Unloading‑Valve unloading valve, clean hydraulic oil circuit and replace filter element.
• Fault 2: Machine Action Weak, System Pressure Abnormal
  Cause: Valve spool jamming, unloading pressure setting deviation.
  Solution: Fit PC60‑7 No‑OEM‑PC60‑7‑Unloading‑Valve unloading valve, adjust pressure value according to machine specification after assembly.
• Fault 3: Abnormal Hydraulic Noise During Standby Status
  Cause: Internal component abrasion, unstable unloading pressure output.
  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.
