Product details
XCMG 60 Distribution Valve SCX120 Detailed Overview
 
I. Core Functional Positioning
 
This distribution valve serves as themain control valve assemblyfor XCMG 60/65-ton excavators, specifically designed for Husco hydraulic systems. Its primary functions include:
 
  • Precise hydraulic flow controlto enable compound movements of actuators such as the boom, arm, and bucket;
 
  • Adjustment of motion speed and forcethrough pressure-flow coupling design, optimizing operational efficiency and stability;
 
  • Integrated safety protection mechanismsto prevent overload or misoperation and extend hydraulic system lifespan.
 
II. Technical Specifications and Performance
 
【表格】
 Parameter Typical Value/Feature
Rated Pressure 350-400 bar (suitable for high-pressure hydraulic systems)
Maximum Flow Rate 400-600 L/min (supports parallel operation of multiple actuators)
Control Sections Multi-section spool valve design (typically 4-6 sections for boom, arm, bucket, swing, etc.)
Control Method Electro-hydraulic proportional control (response time ≤50ms, accuracy ±1%)
Ingress Protection IP68 (dustproof and waterproof, suitable for harsh construction environments)
Material & Craftsmanship Forged steel body with surface hardening treatment, enhancing impact and fatigue resistance by 30%
 
III. Design Highlights
 
  1. Modular Spool Valve Structure
 
      • Independent spool, spring, and seal components allow for easy maintenance and cost reduction of 40% without full replacement;
 
      • Customizable spool combinations to adapt to different operating conditions.
 
  2. Intelligent Control Integration
 
      • Built-in pressure sensors and proportional solenoids for closed-loop motion control;
 
      • Compatible with CAN bus protocol for seamless communication with the excavator's main control system.
 
  3. High Reliability Design
 
      • Dual redundant oil circuits with automatic failover to backup channels in case of single channel failure;
 
      • High-temperature resistant sealing materials (Viton) for operating temperatures ranging from -30℃ to 120℃.
 
IV. Typical Application Scenarios
 
  • Infrastructure Construction: Controls excavation of earth and grasping of rocks;
 
  • Mining Operations: Cooperates with hydraulic breakers for secondary crushing;
 
  • Emergency Rescue: Enables precise operations to avoid secondary collapses;
 
  • Spare Parts & Maintenance: Serves as a core component replacement for main valves, improving repair efficiency by 50%.
 
V. Industry Recognition
 
This distribution valve holds over 35% market share in 6-8-ton excavators, renowned for itshigh response speed(20% faster than comparable products) andlow failure rate(MTBF ≥8000 hours). Users praise its superior coordination in compound movements, making it particularly suitable for high-intensity continuous operations.
