35-8 / 45-8 Hydraulic Distributing Control Valve Assembly | Aftermarket Hydraulic Replacement Spare Parts Compatible With Excavator Using 35-8 / 45-8 Main Valve System

Welcome to HanRui hydraulic supply. We specialize in providing the complete 35-8 / 45-8 excavator multi-way distributing control valve assembly, precision-manufactured as a heavy-duty aftermarket replacement part compatible with large engineering machinery equipment that adopts 35-8 / 45-8 main valve system. All internal valve spools, valve blocks and sealing assemblies are CNC precision machined and passed strict factory pressure & flow testing, stable multi-way hydraulic output for open-pit mining and mass earthwork construction, plug-and-play direct fit without modification, cost-effective overhaul component for global heavy machinery repair workshops.

• Africa & Australia open-pit mine ore stripping, bulk ore heavy transportation & loading auxiliary operation
• Southeast Asia mountain earthwork development, ultra-deep foundation pit excavation for hydropower stations
• Europe & Middle East highway, high-speed rail and large bridge foundation construction
• Super-large river dredging, reservoir reinforcement and flood control water conservancy project
• Coastal bulk port yard expansion, heavy bulk mineral cargo loading operation
• Urban super-large municipal infrastructure reconstruction, deep pipeline and high-rise basement excavation

• Valve spool sticking causes unresponsive boom, arm and bucket action
• Internal valve leakage leads to automatic cylinder sinking when machine static
• Valve joint oil stain and frequent hydraulic oil consumption
• Overflow valve failure triggers system overpressure and hydraulic high temperature alarm
• Unstable flow output leads to digging jitter under heavy mining load

• Insufficient system hydraulic pressure, slow machine movement caused by pump piston and valve plate internal wear
• Pump abnormal overheating and metal knocking vibration, cavitation caused by blocked oil suction filter
• Pump front shaft oil seal leakage, continuous hydraulic oil loss and frequent oil replenishment
• Long-term high temperature accelerates pump core aging damage

• Swing weak & slope sliding: Internal seal aging leads to high-pressure oil internal leakage, machine cannot stay steady on slopes
• Swing abnormal noise & jitter: Worn reducer bearing and gear friction produce loud vibration noise
• Swing oil leakage: Front oil seal abrasion causes continuous hydraulic oil spillage
• Swing stuck rotation: Deformed piston blocks smooth rotary movement under full mining load
• Swing overheating: Long continuous rotation triggers whole hydraulic system high temperature failure

• Inconsistent two-side motor displacement leads to excavator travel deviation
• Broken travel reducer gear results in unilateral no driving force
• Slow climbing and heavy-load stall on mountain mine roads
• Long-term operation produces gear wear noise and persistent oil leakage

• Engine power drop causes insufficient hydraulic valve output under heavy mining load
• Black exhaust smoke and excessive fuel consumption when multi-way valve works at full flow
• Engine cooling system blockage accelerates whole machine overheating

• 100% consistent mounting dimension compatible with machinery using 35-8 / 45-8 main valve system, no cutting or refitting required
• Precision CNC machined valve spool & valve block, tiny matching clearance, greatly reduce internal leakage
• 100% factory pressure, flow and sealing pressure testing before delivery, reduce on-site overhaul failure rate greatly
• High temperature resistant fluorine rubber sealing parts, adapt tropical high-temperature mining construction sites
• Support single piece trial order and large batch wholesale for global machinery repair shops & spare parts distributors
• Export shockproof wooden case packaging to avoid collision damage during long-distance sea transportation
• 6 months full factory official quality warranty for all 35-8 / 45-8 distributing valve assemblies

• Model Number: 35-8 / 45-8
• OEM Reference Part No: 723-46-14600
• Applicable Equipment: Heavy Construction Excavator Equipped With 35-8 / 45-8 Main Valve System
• Product Form: Complete Aftermarket Multi-way Hydraulic Distributing Control Valve Assembly
• Core Function: Control boom, arm, bucket and swing multi-way hydraulic flow
• Warranty Period: 6 Months Factory Quality Warranty
