Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Fluid Control: Designed to regulate the flow of water, oil, and gas in medium-pressure systems through a double eccentric disc mechanism, ensuring tight sealing and minimal leakage.
  • Manual Operation: Equipped with a durable handle for precise, manual control, ideal for applications requiring direct user intervention.

Key features

  • 1. Corrosion-Resistant Cast Material & Soft Sealing

    • With a robust cast iron/steel body and soft sealing technology, you can ensure long-lasting durability and airtight seals even in harsh environments with corrosive fluids like oil or chemicals. This design outperforms traditional valves with rigid seals by reducing leakage risks by up to 30%*.

  • 2. Double Eccentric Design for Smooth Operation

    • With the double eccentric disc mechanism, you can achieve effortless manual operation and precise flow control with minimal torque, making installation and maintenance 40% faster than standard butterfly valves*.

  • 3. High-Efficiency Medium-Pressure Handling

    • With a rated medium-pressure capacity and optimized disc vanes, you can manage fluid flow (water, oil, gas) at speeds up to 2x faster than conventional butterfly valves*, ensuring efficient performance in industrial pipelines.

  • 4. Multi-Media Versatility for Industrial Applications

    • With compatibility for gas, oil, and water, you can deploy this valve across diverse scenarios—from commercial water systems to oil refinery pipelines—without compromising adaptability or safety*.

  • 5. EU-Certified Safety & Compliance

    • With CE and PED certifications, you can guarantee compliance with EU safety and pressure equipment regulations, ensuring reliable operation in regulated industrial environments*.

Supplier's note

  1. Technical Breakthroughs:

    • Double Eccentric Design: Reduces friction by 20% compared to traditional butterfly valves, enabling smoother operation under fluctuating pressures.
    • Soft Sealing Technology: Ensures zero leakage even in abrasive media like slurry, outperforming rigid seals by 30%.
    • PED Compliance: Meets stringent EU pressure equipment directives, ensuring safety in high-risk applications.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard water/gas systems where manual operation and moderate pressure suffice (e.g., municipal pipelines).
    • Advanced Model: Tailored for industries requiring temperature extremes (e.g., chemical processing) or motorized automation.
    • Pro Model: Designed for corrosive environments (e.g., offshore oil rigs) with its stainless steel body and premium pressure tolerance.

Pro Model’s 13 bar rating exceeds industry benchmarks by 25%, enabling use in high-pressure gas distribution networks.
