Supplier's note

  1. Technical Breakthroughs:

    • Pro Model’s 480 bar pressure rating exceeds industry standards by 20%, enabling safer operation in ultra-high-pressure systems.
    • Advanced threading design reduces leakage by 25% compared to traditional valves.
    • Corrosion-resistant coating extends lifespan by 1.5x in marine environments.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard excavators operating in moderate conditions (e.g., urban construction).
    • Advanced Model: Suitable for heavy-duty mining or industrial sites requiring extended temperature tolerance.
    • Pro Model: Recommended for extreme applications (e.g., Arctic drilling or high-temperature refineries) where durability and pressure resistance are critical.

With the Pro Model’s 480 bar rating, you can handle extreme hydraulic loads without system failure. Pair its 7mm thick material with Arctic-grade coatings to ensure seamless operation in sub-zero environments. The Advanced Model’s 420 bar capacity, meanwhile, balances cost and performance for most construction fleets.
