Installation & Verification Guidelines
  • Verify VOE part number and confirm main control valve assembly compatibility, including boom, arm, bucket, travel, swing spools, relief valves, and holding valves.
  • New or remanufactured valves must include hydraulic bench test reports for pressure, flow, and internal leakage of each section.
  • For remanufactured valves, confirm spools are honed, repaired, or new. Replace all O-rings.
  • Inspect valve block for casting cracks and sand holes upon arrival. Seal oil ports to prevent dirt and contaminants from entering valve cavity.
  • Secure valve firmly during transportation to avoid impact damage to valve block, port threads, and precision spools.
  • Clean hydraulic tank and pipelines before installation, replace all hydraulic filters, and fully bleed air from hydraulic system.
  • Test compound movements, cylinder drift, and system relief pressure after installation. Check for jerky operation, abnormal noise, and oil seepage.
Common Faults & Symptoms
  • Spool and Valve Bore Wear, Large Internal Leakage
    • Symptoms: Weak digging power; performance worsens when hot; boom/arm cylinder sinks
    • Cause: Dirty hydraulic oil scratches spool and valve bore
  • Spool Stuck, Slow or Jerky Movement
    • Symptoms: Slow boom, arm, bucket and swing action; compound operation poor
    • Cause: Oil contamination, oil sludge, damaged return spring
  • Relief Valve and Pressure Compensator Failure, Insufficient System Pressure
    • Symptoms: Low working pressure, pressure fluctuation, whistling noise
    • Cause: Worn valve core, spring fatigue, clogged damping hole
  • O-ring Damage, External Oil Leakage
    • Symptoms: Oil seepage between valve slices and end covers
    • Cause: Aged sealing rings, loose bolts, air suction causing cavitation
  • Holding Valve Seal Failure, Cylinder Drift
    • Symptoms: Boom and arm sink slowly, worse under heavy load
    • Cause: Contamination or wear on holding valve sealing surface
  • Valve Block Cracking (Rare but Serious)
    • Symptoms: Sudden heavy oil leakage, unable to build hydraulic pressure
    • Cause: Long-term pressure impact, uneven bolt tightening torque, casting defects
