Insufficient flow of main control valve, weak machine performance and slow operation speed
Spool sticking, single function failure and uncoordinated combined movements
Internal leakage of valve block, insufficient pressure under load and speed drop during operation
External oil leakage on valve body, aged and damaged seals and O-rings
Wear of valve bore and spool, fluctuating system pressure and jerky operation
Relief valve malfunction, system pressure fails to build up or rises abnormally high
Purchasing Recommendations
Verify part numbers and machine serial number to confirm compatibility with Komatsu PC850 hydraulic excavator
Prioritize OEM parts or high-quality remanufactured parts; be cautious of low-cost generic spare parts
Inspect valve body for cracks, check integrity of port threads and mounting flange before acceptance
Confirm the main control valve assembly comes with a complete seal kit for easy installation and replacement
Request warranty from supplier and retain factory inspection report
Clean hydraulic tank, replace hydraulic oil and flush pipeline contaminants during valve replacement to prevent secondary wear
