PC200-6 Excavator Multi-way Distributing Control Valve | Aftermarket Hydraulic Replacement Spare Parts

Welcome to our hydraulic spare parts supply. We specialize in providing the complete PC200-6 excavator multi-way distributing control valve assembly, precision-manufactured as a heavy-duty aftermarket replacement part compatible with Komatsu medium-large engineering machinery equipment. All internal spools, valve bodies and sealing assemblies are CNC precision machined and passed factory pressure & flow testing, stable heavy-load flow distribution for mining and large earthwork construction, plug-and-play direct fit without modification, cost-effective overhaul component for global heavy machinery repair workshops.

• Urban large municipal road reconstruction, super-large pipeline trenching and commercial high-rise deep foundation excavation
• Massive earthwork site development, mountain leveling and deep foundation pit excavation engineering
• Highway & high-speed rail roadbed construction, large bridge pier earthwork and mountain slope stabilization trimming project
• Open-pit large mining site stripping, bulk ore loading and mine heavy transportation auxiliary operation
• Large river dredging, reservoir reinforcement and flood control water conservancy project
• Large port yard expansion, logistics park construction and heavy bulk cargo loading operation

• Spool sticking, heavy operation handle, poor return and unresponsive digging action caused by hydraulic impurity wear
• Internal valve leakage, slow boom / arm / bucket movement and cylinder drift when machine stays static
• External oil leakage at valve body joints, continuous hydraulic oil consumption and surface oil stain
• Unstable flow output, machine shaking and uneven movement during long-time continuous heavy load operation
• Unbalanced pressure of each oil circuit, insufficient digging force and slow traveling speed under heavy load
• Overflow valve failure, unable to build system pressure or excessive pressure triggering high temperature alarm

• Insufficient system pressure, slow whole machine movement caused by worn valve plate, piston and cylinder block internal leakage
• Pump abnormal overheating and metal knocking vibration, cavitation from clogged oil suction strainer
• Pump front shaft oil seal leakage, hydraulic oil leaking to engine compartment and continuous oil consumption
• Unstable hydraulic flow, boom and bucket jitter, weak digging force under heavy load
• Hydraulic pump cavitation noise, air mixed in oil circuit leading to pressure fluctuation and power drop
• Hydraulic system high temperature alarm, continuous operation leads to obvious power limitation

• Swing weak & sliding slope: Serious wear of motor valve plate or aging internal seal leads to high-pressure oil internal leakage, unable to stop on slope
• Swing abnormal noise & sticking: Broken gear or damaged bearing inside reducer, with metal friction jamming sound
• Swing oil leakage: Oil seal abrasion leads to swing motor hydraulic oil spillage
• Swing stuck, excavator unable to rotate smoothly under full load
• Long-time continuous swing operation causes whole hydraulic system overheating

• Travel deviation: Inconsistent displacement of two side motors, servo valve failure or oil seal leakage of central swing joint
• One side unable to travel: Broken travel reducer gear or the motor brake cannot open normally
• Weak travel or abnormal speed: Motor displacement adjustment mechanism stuck in large displacement state, slow speed with huge torque
• Travel gear wear noise and oil leakage failure
• Climbing stall caused by internal transmission parts wear

• Engine power drop & black smoke: Clogged air filter or poor atomization of fuel injection parts
• Water temperature & oil temperature over high: Radiator blocked by sediment, deteriorated engine oil, stuck thermostat
• Difficult start: Starter failure, battery power loss or air entering fuel pipeline
• Engine surge when multi-way valve opens multi hydraulic circuits
• Engine power reduction caused by valve blockage and hydraulic pressure loss

• Thickened CNC machined valve body and wear-resistant hard chrome spool, tiny matching clearance, effectively reduce internal leakage under long heavy mining load
• Complete original matching installation size as direct replacement compatible with Komatsu PC series medium-large excavator, direct disassembly replacement without cutting or modification
• 100% factory flow & pressure testing before delivery, effectively reduce on-site breakdown rate after installation
• High temperature & pressure resistant fluorine rubber sealing components, adapt 24h continuous heavy-load construction operation
• Support 1 piece trial order and mass bulk wholesale for global large excavator repair shops & distributors
• Standard export shockproof wooden case packaging to avoid valve body collision damage during long-distance sea transportation
• 6 months full factory quality warranty for all PC200-6 distributing valves

• Model Number: PC200-6
• Product Type: Multi-way Main Control Distributing Valve
• Compatible Equipment: Komatsu PC Series Medium-Large Excavator Construction Machinery
• Condition: Brand New Aftermarket Replacement Hydraulic Spare Parts
• Core Function: Control Boom, Arm, Bucket, Travel and Swing Hydraulic Circuit
• Warranty Period: 6 Months Factory Quality Warranty
