Main Features

  • Integral Forged Steel Material: The valve body is made of integral forged steel (A105), featuring high strength, high toughness, and excellent corrosion resistance, suitable for high-pressure and harsh working conditions.

  • Flange Connection: Adopts RF (Raised Face) connection method, conforming to ANSI B16.5 standard, with reliable sealing performance and easy integration with pipeline systems.

  • Swing-Type Structure: The disc adopts a swing design, which automatically opens when the medium flows and closes when the medium flows in the reverse direction, ensuring one-way flow of the medium and preventing backflow.

  • High Sealing Performance: Equipped with high-quality sealing materials to ensure zero leakage under high-pressure conditions. The tight fit between the disc and the valve seat can effectively prevent medium backflow.

  • Fire-Safe Design: Complies with API 607 fire safety standards, ensuring sealing performance is maintained even in extreme situations such as fires.

  • Anti-Static Design: Prevents static accumulation caused by medium flow, improving safety.

  • Compact Design: With a compact structure, small volume, and light weight, it saves installation space and is easy to transport and maintain.

  • Multiple Operation Methods: Can be equipped with manual, pneumatic, or electric actuators to meet different operational needs.

Technical Specifications

  • Nominal Diameter: 1/2" to 2" (DN15 to DN50)

  • Pressure Rating: 150LB ~ 2500LB 

  • Applicable Media: Petroleum, natural gas, water, steam, air, oil products, etc.

  • Applicable Temperature: -29℃ to 425℃ (the temperature range may vary depending on the sealing material)

  • Valve Body Material: Integral forged steel A105

  • Sealing Material: Stainless steel, PTFE, cemented carbide, etc.
