ZX200-2 Excavator Multi-way Distributing Control Valve | Aftermarket Hydraulic Spare Parts For ZX Series Medium-Large Excavator

ZX200-2 multi-way distributing valve is core hydraulic control component compatible with ZX series medium-large excavator construction machinery. All internal spools, valve bodies and sealing assemblies are precision machined and passed factory pressure & flow testing, stable flow distribution for heavy-load construction operation, plug-and-play direct replacement without modification, cost-effective overhaul spare part for global earthwork, mining and municipal machinery repair workshops.

• Urban municipal road reconstruction, small pipeline trenching and residential & commercial building foundation excavation
• Farm land reclamation, orchard digging and rural irrigation water conservancy projects
• Hillside trimming, village road construction and small indoor foundation engineering
• Port yard ground leveling, logistics yard renovation and light & heavy bulk cargo loading operation
• Large earthwork site development, mountain land leveling and deep foundation pit excavation engineering
• Open-pit mining site stripping, bulk ore loading and mine auxiliary transportation operation
• River dredging, reservoir reinforcement and flood control water conservancy project
• Highway roadbed construction, bridge pier earthwork and mountain slope stabilization trimming project

• 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

• Precision CNC machined thickened valve body and wear-resistant spool, tiny matching clearance, effectively reduce internal leakage under long heavy load
• Complete original matching installation size for ZX200-2 ZX series 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 sealing components, adapt long-time continuous heavy-load construction operation
• Support 1 piece trial order and mass bulk wholesale for global medium-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 ZX200-2 distributing valves

• Model Number: ZX200-2
• Product Type: Multi-way Main Control Distributing Valve
• Compatible Equipment: ZX 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
