3. Common Stop Valve Failure Troubleshooting

• Fault 1: Poor Cut‑off Performance, Oil Circuit Cannot Close Completely
  Cause: Internal spool wear, sealing surface damage, hydraulic impurity contamination.
  Solution: Install brand‑new stop valve, flush hydraulic circuit and replace hydraulic filter element.
• Fault 2: Internal Leakage inside Stop Valve Assembly
  Cause: Spool abrasion, seal aging, pressure impact damage.
  Solution: Replace complete stop valve assembly, inspect hydraulic oil cleanliness.
• Fault 3: Oil Leakage on Mounting Surface
  Cause: Gasket aging, mating surface scratch, uneven bolt tightening.
  Solution: Fit new stop valve, check mounting‑surface flatness, tighten bolts evenly.
• Fault 4: Abnormal Hydraulic Oil‑circuit Control
  Cause: Internal component fatigue, foreign particles trapped inside valve chamber.
  Solution: Replace full stop valve assembly, clean the whole hydraulic oil loop.
