Product Description

KMX32N Main Control Valve Distributor for SANY SY365 SY375 SY385 SY465 SY485

Installation & Verification Guidelines

Verify KMX32N 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
