Product Description

LG220 Excavator KMX15RB Excavator Main Control Valve Assy Hydraulic Control Valve Machinery Parts

 

    • Sluggish or weak performance: Insufficient main relief valve pressure, worn spools causing internal leakage, jammed negative‑flow/LS valves. Measure system pressure, check spools after disassembly, clean valve parts.
    • Unsteady/jittery operation: Damaged spool surfaces, spring degradation, fluctuating pilot pressure. Polish or renew spools and springs, calibrate pilot pressure values.
    • Hydraulic oil seepage: Worn seals, valve body cracks. Replace sealing components; weld fractures or replace the valve body entirely.
    • Poor compound‑action synchronization: Sticky flow‑combining valves, faulty load check valves. Clean merging valves and inspect check‑valve tightness.
      Commonly named the multi‑way valve or main valve, the main control valve of an excavator acts as the primary switch and flow divider manifold within the hydraulic system. It serves as the central control station for all working movements: boom lifting, arm retracting, bucket digging, slewing and bidirectional traveling.

      Functions

      It takes in high‑pressure oil output from the main hydraulic pump.
      Operating the control lever enables pilot oil to push each spool inside the valve body.
      High‑pressure oil is accurately routed to relevant cylinders and motors:
      Boom cylinder – boom up‑and‑down motion
      Arm cylinder – arm extension and retraction
      Bucket cylinder – bucket opening and closing
      Swing motor – machine rotation
      Travel motor – forward and reverse travel

      Common Faults & Troubleshooting

    Serving as the hydraulic flow distribution hub, the main control valve precisely distributes main‑pump high‑pressure oil to boom, arm, bucket, swing and travel mechanisms, controlling movement direction, speed and combined‑action harmony.
