3. Common Travel Relief Valve Failure Troubleshooting

• Fault 1: Excavator Slow Travel, Weak Driving Performance
  Cause: Valve spool wear, internal impurity clogging, spring fatigue deformation.
  Solution: Install new No‑OEM‑EX220‑3‑Travel‑Relief‑Valve travel relief valve, clean hydraulic oil circuit and replace filter element.
• Fault 2: Travel Circuit Over‑pressure, Travel Motor Easy To Damage
  Cause: Valve spool jamming, pressure‑limiting function failure.
  Solution: Fit EX220‑3 No‑OEM‑EX220‑3‑Travel‑Relief‑Valve travel relief valve, calibrate travel circuit pressure to standard value after assembly.
• Fault 3: Hydraulic Vibration & Abnormal Noise While Traveling
  Cause: Internal component abrasion, unstable pressure overflow.
  Solution: Replace complete valve assembly, inspect hydraulic oil cleanliness condition.
• Fault 4: Hydraulic Oil Leakage At Thread Connection Joint
  Cause: Sealing ring aging, thread surface scratch damage.
  Solution: Replace whole valve unit or matching seal repair kit.
