3. Common Stop Valve Failure Troubleshooting

• Fault 1: Hydraulic Oil Circuit Cannot Be Cut Off
  Cause: Internal spool jam, sealing surface wear, hydraulic oil impurity contamination.
  Solution: Install brand‑new 16‑hole stop valve, flush hydraulic circuit and replace hydraulic filter element.
• Fault 2: Stop Valve Block Jamming
  Cause: Foreign particles stuck inside oil‑passage, internal component deformation, oil dirt accumulation.
  Solution: Replace complete stop valve assembly, clean whole hydraulic oil loop.
• Fault 3: Internal Leakage of Stop Valve Assembly
  Cause: Sealing face scratch, seal ring aging, long‑term high‑pressure impact damage.
  Solution: Fit new 16‑hole stop valve, inspect connected hydraulic pipeline wear status.
• Fault 4: Hydraulic Oil Passage Blockage
  Cause: Metal debris and dirt accumulated inside 16‑hole oil channels.
  Solution: Replace full stop valve assembly, clean hydraulic tank and filter parts.
