Common Faults
  • Slow and weak machine movements
  • Weak operation of single actuator (boom / arm / bucket / swing / travel)
  • Jerky and vibrating movement
  • Interference during combined operation, poor flow merging
  • External leakage of main control valve, oil seepage and oil leakage on valve body
  • Severe internal leakage, rapid pressure drop and poor pressure retention
  • Spool sticking, no response of corresponding function
  • Worn overload relief valve, low system pressure
  • Damaged check valve, abnormal return of operation
  • Scuffed valve bore, continuously increasing internal leakage
  • Unstable pilot control pressure, erratic movement speed
  • Aging and failure of seals, multiple oil leaks

Procurement Recommendations
  • Prioritize internal leakage test to decide repair or full assembly replacement
  • Replace the whole main control valve assembly if valve bore is severely scuffed
  • For slight spool wear, replace spool and seal kit separately
  • Verify part numbers when purchasing relief valves and check valves
  • Adopt high-quality seals to avoid repeated oil leakage in short term
  • Inspect appearance before delivery to ensure no sand holes or cracks on valve body
