3. Common Travel Relief Valve Failure Troubleshooting

• Fault 1: Excavator Travel Weak & Slow Movement
  Cause: Spring fatigue, spool wear, hydraulic oil mixed with impurities.
  Solution: Install brand‑new travel relief valve, flush hydraulic circuit and replace filter element.
• Fault 2: Travel Circuit Pressure Fluctuation
  Cause: Internal component abrasion, foreign particles stuck inside valve body, spring deformation.
  Solution: Replace complete travel relief valve assembly, clean the whole hydraulic oil loop.
• Fault 3: Valve Spool Sticking
  Cause: Metal debris and oil sludge enter valve interior, part deformation.
  Solution: Fit new travel relief valve, thoroughly clean hydraulic tank and oil passages.
• Fault 4: Internal Leakage of Travel Valve Assembly
  Cause: Sealing surface scratch, long‑term high‑pressure impact damage.
  Solution: Replace travel relief valve, check wear condition of matched hydraulic pipelines.
