3. Common Shut‑off Valve Failure Troubleshooting

• Fault 1: Internal and External Oil Leakage
  Cause: Seal wear, valve body scratch, hydraulic oil impurity erosion.
  Solution: Install brand‑new shut‑off valve, clean hydraulic circuit and replace filter element.
• Fault 2: Spool Stuck, Hard to Switch
  Cause: Dirt and metal particles accumulated inside valve cavity.
  Solution: Replace complete shut‑off valve, flush the whole hydraulic oil passage.
• Fault 3: Cannot Fully Cut‑off Hydraulic Oil Circuit
  Cause: Sealing surface damage and deformation.
  Solution: Fit new shut‑off valve, test oil circuit cut‑off effect after installation.
• Fault 4: Hydraulic Vibration and Abnormal Noise
  Cause: Internal parts wear, hydraulic pressure shock impact.
  Solution: Replace shut‑off valve and inspect system pressure fluctuation status.
