Supplier's note

  1. Three Technical Breakthroughs:

    • Aluminum Alloy Body: 20% lighter than steel valves, reducing trailer weight while maintaining strength.
    • Triple-Seal Port Design: Reduces leakage by 90% compared to standard valves.
    • Temperature-Resistant Coating: Operates safely in -40°F (-40°C) environments, 25% colder than industry norms.
  2. Optimal Version Selection:

    • Base Model: Ideal for standard trailers with routine maintenance needs.
    • Advanced Model: Preferred for heavy-haul trucks requiring higher pressure tolerance (e.g., logging or construction).
    • Pro Model: Best for extreme-use scenarios (e.g., oilfield or Arctic transport), where lightweight and ultra-high PSI are critical.

With the Pro Model’s 160 PSI rating, you can safely handle high-pressure braking systems in rugged terrains. Pair its ISO 14067 certification with the triple-seal ports to ensure zero leakage during prolonged use. The Base Model’s FMVSS 106 compliance makes it cost-effective for everyday fleet maintenance.
