Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Fluid Control: Manual operation of air, oil, and water flow via a robust trunnion-mounted ball design, ensuring tight sealing and minimal leakage.
  • Pressure Adaptability: Supports low, medium, and high-pressure applications, making it versatile for diverse industrial requirements.

Key features

  • 1. Corrosion-Resistant WCB Material Technology

    • With a WCB (Welded Carbon Steel Body) construction and a corrosion-resistant blue coating, you can ensure durability in harsh industrial environments like oil refineries and chemical plants. This material outperforms standard carbon steel in resisting rust and wear, extending operational lifespan.

  • 2. Ergonomic Interactive Design

    • With a notched, oversized manual handle and trunnion-mounted design, you can achieve secure, effortless operation even under high-pressure conditions. The robust handle design provides ~30% better grip strength compared to smooth handles, reducing user fatigue during frequent adjustments.

  • 3. High-Pressure Performance Capability

    • With a trunnion-mounted ball valve structure, you can reliably handle pressures up to high-pressure ratings (e.g., 600 PSI), outperforming standard floating ball valves by ~25% in stability under extreme conditions.

  • 4. Versatile Scenario Adaptability

    • With compatibility for air, oil, and water media, you can deploy this valve across diverse industrial applications—from pipelines in power plants to chemical processing systems—ensuring seamless fluid control in demanding scenarios.

  • 5. API Standard Compliance

    • With API 6D certification and WCB material adherence, you can meet strict industrial safety and performance standards, ensuring reliability in regulated environments.

Supplier's note

  1. Technical Breakthroughs:

    • Trunnion-Mounted Design: Reduces torque by 30% compared to floating ball valves, enabling smooth operation under high pressure.
    • WCB Material: Triple the corrosion resistance of cast iron, ensuring longevity in chemical plants.
    • Flanged Connections: 20% faster installation than threaded valves, reducing downtime.

  2. Version Selection Guide:

    • Base Model: Optimal for general industries (e.g., water treatment) requiring ANSI 600 pressure.
    • Advanced Model: Suitable for oil & gas pipelines needing ANSI 900 pressure and API 6D compliance.
    • Pro Model: Designed for high-pressure critical applications (e.g., deep-sea drilling) with ISO-certified durability.

With the Pro version’s WC9 material and API 600/ISO 15848 dual certification, users can safely handle extreme temperatures and corrosive fluids. Pair it with Duplex stainless coatings to achieve zero leakage in offshore platforms.
