Description
Main Control Valve Distributor for Hitachi EX200-5 EX210H-5 EX210LCH-5 EX220-5 EX270-5 Direct Injection Excavator Part No 4366959
Installation & Verification Guidelines
  • Verify Hitachi 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
