3. Common Suction Valve Failure Troubleshooting

• Fault 1: Excavator Hydraulic System Produces Cavitation Knocking Noise
  Cause: Internal spool wear, spring fatigue, dirt impurity trapped inside valve clearance.
  Solution: Install brand‑new No‑OEM‑PC200‑6‑Suction‑Valve Suction Valve, flush hydraulic circuit and replace hydraulic filter.
• Fault 2: Working Movements Are Jerky And Not Smooth
  Cause: Valve core abrasion, reset spring performance degradation.
  Solution: Fit PC200‑6 No‑OEM‑PC200‑6‑Suction‑Valve Suction Valve, thoroughly clean whole hydraulic oil loop.
• Fault 3: Partial Hydraulic Function Output Unstable
  Cause: Internal component wear, oil passages blocked by hydraulic contamination.
  Solution: Replace complete suction valve assembly, inspect hydraulic oil cleanliness status.
• Fault 4: Oil Leakage On Suction Valve Mounting Surface
  Cause: Seal ring aging, mating surface scratch damage.
  Solution: Change full suction valve assembly or matching seal repair kit.
