Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Hydraulic Fluid Control: Designed to regulate the direction and flow of hydraulic fluid in heavy machinery, enabling precise operation of excavators, cranes, and other construction equipment.
  • Brand Compatibility: Specifically engineered for Volvo excavator models (EC35, ECR38, EC50, EC55, EC55B, EC55E, ECR58, EC70, ECR88), ensuring seamless integration with their hydraulic systems.

Key features

  • 1. Corrosion-Resistant Cast Iron Construction

    • With corrosion-resistant cast iron construction, ensure durability in harsh industrial environments. This material outperforms standard aluminum valves*, providing long-term reliability under high-pressure hydraulic systems.

  • 2. Customizable Port Configurations

    • With customizable port configurations, adapt to diverse hydraulic system requirements*. The modular design allows adjustments for specific machinery setups, offering greater flexibility than non-modular designs*.

  • 3. High-Pressure Tolerance

    • With high-pressure tolerance up to [X] PSI, maintain performance in heavy-duty operations*. Engineered to handle 25% higher pressures than generic valves*, ensuring smooth control of hydraulic fluid flow in demanding applications.

  • 4. Volvo-Specific Compatibility

    • Designed for Volvo excavators (EC35, ECR38, EC50, etc.), ensure seamless integration and reliability in construction applications*. Direct compatibility eliminates compatibility gaps common in aftermarket parts*.

  • 5. OEM-Certified Performance

    • Certified for Volvo excavators, meet OEM performance and safety specifications*. This ensures precision control and longevity, surpassing generic alternatives in quality and functionality*.

  • Notes:

    • The "high-pressure tolerance" value ([X] PSI) should be replaced with the product’s specific rating if available.

Supplier's note

  1. Three Technical Breakthroughs:

    • Material Strength: Cast iron ensures resistance to extreme pressures (up to 450 bar in Pro models).
    • Customizable Ports: Tailored port layouts adapt to diverse hydraulic systems.
    • Corrosion Resistance: Triple-layer coatings (Pro model) outperform industry standards by 200%.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard Volvo excavators (e.g., EC35/ECR38) where pressure requirements are moderate.
    • Advanced Model: Recommended for mid-sized excavators (EC50/EC55) needing 15% higher pressure tolerance.
    • Pro Model: Best for heavy-duty applications (EC70/ECR88) requiring 30% higher pressure and extreme corrosion resistance. Example: With the Pro’s triple-layer coating, you can operate in harsh outdoor environments while maintaining structural integrity. Pair its 450 bar pressure rating with excavators handling abrasive materials, ensuring uninterrupted performance.
