ZX350-6 Excavator Multi-way Distributing Control Valve | Aftermarket Hydraulic Spare Parts For Large Excavator
Restore full hydraulic control performance with the ZX350-6 excavator multi-way distributing valve assembly, designed as a direct-fit aftermarket replacement spare part compatible with Hitachi ZX series large heavy construction machinery. ZX350-6 multi-way distributing valve is core hydraulic control component for 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 mining & infrastructure construction operation, plug-and-play direct replacement without modification, cost-effective overhaul spare part for global mine, large earthwork and municipal machinery repair workshops.
- Large urban municipal road reconstruction, large-diameter pipeline trenching and commercial high-rise building deep foundation excavation
- Massive earthwork site development, mountain land 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 mining site stripping, bulk ore loading and mine auxiliary transportation heavy-duty 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
- Quarry stone excavation and aggregate loading production line supporting work
- 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 mining load
- Complete original matching installation size for ZX350-6 large excavator, direct disassembly replacement without cutting or modification, compatible with Hitachi ZX series large machines
- 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 mining 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 ZX350-6 distributing valves
- Model Number: ZX350-6
- Product Type: Multi-way Main Control Distributing Valve
- Compatible Equipment: ZX Series Large Excavator Construction Machinery, aftermarket replacement compatible with Hitachi heavy excavator
- Condition: Brand New Aftermarket Replacement Hydraulic Spare Parts
- Core Function: Control Boom, Arm, Bucket, Travel and Swing Hydraulic Circuit
