2. Application Scope

Perfectly fits PC130‑7 excavator hydraulic pressure control system and construction machinery overhaul works:

• Hydraulic Overhaul: Direct replacement for worn, stuck or damaged original relief valve assembly.
• Pressure‑Fault Repair: Troubleshoot low digging power, pressure drift and hydraulic overflow noise.
• Repair Workshop: Accurate dimensional match, convenient installation, stable pressure‑limiting performance.
• Overseas Parts Dealer: Stable inventory supply, complete QC records support cross‑border spare‑parts trading.

3. Common Relief Valve Failure Troubleshooting

• Fault 1: Excavator Digging Power Insufficient, System Pressure Low
  Cause: Valve spool wear, internal dirt blockage, pressure‑control spring fatigue.
  Solution: Install brand‑new No‑OEM‑PC130‑7‑Relief‑Valve relief valve, flush hydraulic circuit and replace filter element.
• Fault 2: Hydraulic System Generates Obvious Overflow Noise
  Cause: Spool sticking, internal oil channel blocked by impurities.
  Solution: Fit PC130‑7 No‑OEM‑PC130‑7‑Relief‑Valve relief valve, thoroughly clean the whole hydraulic oil loop.
• Fault 3: Machine Jitter While Working, Pressure Fluctuates Violently
  Cause: Internal component abrasion, valve core clearance over tolerance.
  Solution: Replace complete relief valve assembly, check hydraulic oil cleanliness condition.
• Fault 4: Oil Leakage At Relief Valve External Joints
  Cause: Seal ring aging, mating surface scratch damage.
  Solution: Change full valve assembly or matching seal repair kit.

5. Frequently Asked Questions

Q1: How do I confirm this relief valve fits my excavator?
A: Please confirm excavator model, mounting dimension and hydraulic pressure parameters, provide No‑OEM‑PC130‑7‑Relief‑Valve for fast compatibility verification.

Q2: What quality inspection will be carried out before goods dispatch?
A: Every PC130‑7 relief valve undergoes strict hydraulic flow and pressure test to guarantee stable pressure‑limiting performance.

Q3: What points need attention while installing relief valve?
A: Keep mounting surface clean to prevent dirt entering valve interior, exhaust air from hydraulic circuit after finishing installation.
