Applicable scenarios

Unique advantages

  • Double Block and Bleed (DBB) Functionality: Ensures complete isolation of fluid flow and safe bleed-off in high-pressure systems, critical for maintenance and process safety.
  • Precision Flow Control: Manual operation via a robust handle allows adjustable flow regulation, ideal for managing corrosive media (acid, oil, base) and water in demanding applications.

Key features

  • 1. Corrosion-Resistant 316SS Material Technology

    • With corrosion-resistant 316SS stainless steel, ensure durability in harsh environments with exposure to acid, oil, base, and water. This premium-grade material outperforms standard stainless steel in chemical resistance and longevity*.

  • 2. Ergonomic Manual Handle Design for Interactive Precision

    • With an ergonomic manual handle design, enable precise flow control and easy operation in industrial settings. The prominent handle ensures effortless adjustments even under high-pressure conditions.

  • 3. Extreme High-Pressure Performance (6000 PSI)

    • Withstanding up to 6000 PSI pressure, handle extreme conditions surpassing standard residential/commercial systems*. This capability makes it ideal for demanding industrial applications.

  • 4. Versatile Scenario Adaptability with Multiple Ports

    • Designed for high-pressure industrial scenarios, the valve’s multiple ports and directional flow indicators adapt to diverse applications while ensuring correct fluid direction and preventing backflow.

  • 5. Compliance with Industrial Corrosion-Resistance Standards

    • Constructed with 316SS meeting stringent industrial corrosion-resistance standards, ensure compliance in aggressive media environments. This guarantees reliability in chemical processing and other critical operations.

Supplier's note

  1. Three Technical Breakthroughs:

    • Sealexcel Coating: Enhances corrosion resistance by 40% compared to standard 316SS, ideal for acid/oil environments.
    • 6000 PSI Base Pressure: Exceeds industry benchmarks (typically 5000 PSI), enabling use in ultra-high-pressure systems.
    • Precision Needle Valve Design: Achieves ±1% flow accuracy in the Pro Model, critical for lab and pharmaceutical applications.

  2. Optimal Version Selection:

    • Base Model: Suitable for standard industrial plants needing 6000 PSI resistance and basic corrosion protection.
    • Advanced Model: Recommended for chemical processing facilities requiring +15% higher pressure tolerance and improved temperature stability.
    • Pro Model: Best for extreme applications (e.g., deep-sea oil rigs) where triple-industry-standard pressure (7800 PSI) and ultra-precise flow control are mandatory.

Pro Model’s pressure rating is 30% higher than the industry average, enabling safe handling of subsea drilling fluids. Pair its Sealexcel+ coating with the ±1% accuracy to ensure zero leakage in high-stakes scenarios.
