2. Application Scope

This main relief valve is customized for XCMG210 excavator hydraulic overhaul:

• Hydraulic Circuit Overhaul: Direct replacement for original damaged main relief valve assembly.
• Hydraulic Fault Repair: Fix insufficient digging power, unstable system pressure, oil temperature rising fast and internal leakage malfunctions.
• Repair Workshop Usage: Standard installation dimension, convenient pressure adjustment, stable pressure‑limiting performance.
• Overseas Parts Reseller: Stable stock quantity, complete QC documents to support cross‑border excavator spare‑part business.

3. Common Relief Valve Failure Troubleshooting

• Fault 1: Excavator Digging Force Insufficient
  Cause: Valve spool wear, spring fatigue failure, hydraulic oil mixed with impurity particles.
  Solution: Install brand‑new relief valve, flush hydraulic circuit and replace filter element.
• Fault 2: Hydraulic System Pressure Unstable
  Cause: Valve core stuck by dirt, spring deformation, pressure parameter drift.
  Solution: Replace complete relief valve assembly, clean the whole hydraulic oil loop.
• Fault 3: Hydraulic Oil Temperature Rises Rapidly
  Cause: Internal leakage, frequent overflow pressure release, sealing surface abrasion.
  Solution: Fit new main relief valve, check hydraulic pump working status synchronously.
• Fault 4: Abnormal Vibration & Noise of Valve Assembly
  Cause: Spring damage, spool jitter, pressure resonance inside hydraulic circuit.
  Solution: Replace relief valve, inspect pipeline fixing condition.
