Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Fluid Control & Safety: Designed to regulate and shut off fluid flow in industrial systems (e.g., water, gas) with a DN200 lugged wafer flanged butterfly valve. The tamper switch ensures secure operation and prevents unauthorized access.
  • Durability & Compliance: UL FM-approved construction with corrosion-resistant cast iron valve body and robust metal stem, ensuring reliability in high-pressure and harsh environments.

Key features

  • 1. Material Technology

    • With a corrosion-resistant cast iron body and steel valve stem, you can ensure long-lasting durability in harsh industrial environments. The black rubber/plastic valve disc provides a secure seal, preventing leaks even under high-pressure conditions.

  • 2. Interactive Design

    • With a tamper-proof switch and locking mechanism, you can prevent unauthorized operation and ensure secure positioning. The ergonomic handle allows easy manual control, simplifying maintenance and flow adjustments.

  • 3. Performance Parameters

    • With a DN200 size and flanged design, you can handle high-pressure flows efficiently, outperforming standard butterfly valves*. The robust construction supports industrial-grade applications, ensuring reliability in demanding systems.

  • 4. Scenario Solutions

    • Designed for industrial use in water, gas, or chemical systems, this valve adapts to commercial-scale operations. Its manual operation and locking features make it ideal for maintenance-friendly setups, while customizable materials and sizes suit diverse fluid control needs.

  • 5. Certification Standards

    • With UL and FM certifications, you can meet stringent safety and performance standards, ensuring compliance in commercial and industrial settings.

Supplier's note

  1. Three Technical Breakthroughs:

    • Tamper Switch: A unique locking mechanism prevents unauthorized access, ensuring operational integrity.
    • UL FM Certification: Meets rigorous safety standards for use in hazardous environments.
    • Lugged Wafer Design: Reduces installation complexity by 30% compared to traditional butterfly valves.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial water systems where basic pressure (≤10 bar) and corrosion resistance suffice.
    • Advanced Model: Suitable for chemical plants requiring enhanced corrosion resistance (stainless steel) and ISO compliance.
    • Pro Model: Designed for oil/gas sectors with extreme pressure (13 bar) and fire-resistant tamper switches, enabling safe handling of flammable fluids.

Example benefit: "With the Pro Model’s fire-resistant tamper switch, you can ensure valve integrity even in high-temperature emergencies, paired with duplex stainless steel for unmatched durability in offshore pipelines."
