Structural Features

  • Nickel-Aluminum Bronze Material: The valve body is made of ASTM B148 C95800 nickel-aluminum bronze, which has excellent corrosion resistance and high strength, and is particularly suitable for harsh environments such as seawater and chemical media.

  • Swing-Type Design: Adopts a swing-type connection method, ensuring easy installation and tight sealing, and facilitating maintenance and replacement.

  • One-Way Sealing: The unique design ensures that fluid can only flow in one direction, effectively preventing medium backflow and protecting downstream equipment.

  • Low Head Loss: The optimized flow channel design reduces fluid flow resistance, lowers head loss, and improves system efficiency.

  • Automatic Closing Mechanism: When fluid flow stops, the valve disc closes automatically to prevent medium backflow.

  • Compact Design: With small size and light weight, it is easy to install and maintain, making it suitable for occasions with limited space.

Technical Parameters

  • Nominal Diameter: 12" (DN300)

  • Pressure Class: 150LB (PN2.0)

  • Temperature Range: -20℃ to +120℃

  • Materials:

    • Valve Body: ASTM B148 C95800 Nickel-Aluminum Bronze

    • Valve Disc: ASTM B148 C95800 Nickel-Aluminum Bronze

    • Sealing Ring: Nitrile Butadiene Rubber (NBR) or Polytetrafluoroethylene (PTFE)

  • Connection Method: Swing-Type Connection

  • Design Standards: ANSI B16.34, API 6D

  • Testing Standards: API 598, ISO 5208

Application Fields

  • Oil and Natural Gas Industry: Used in oil and gas field exploration, gathering, transportation, and processing systems to prevent backflow of media such as crude oil and natural gas, and protect downstream equipment.

  • Chemical Industry: Suitable for the transportation and reaction systems of various chemical media, preventing medium backflow and ensuring production safety.

  • Water Treatment Industry: Applied in the water supply and drainage systems of water plants and sewage treatment plants to prevent water backflow and protect equipment such as water pumps.

  • Food and Beverage Industry: Meets food-grade requirements and is used in pipeline systems during food and beverage production to ensure hygiene and safety.

  • HVAC: Used in cooling water systems, hot water systems, etc., to prevent water backflow and protect heat exchangers and pumps.

  • General Industrial Applications: Suitable for one-way flow control of media such as water, oil, and gas, ensuring the safe and efficient operation of the system.

Advantages and Value

  • High Reliability: The nickel-aluminum bronze material and swing-type design ensure the check valve operates stably in high-pressure and high-temperature environments, reducing maintenance frequency and downtime.

  • High Safety: The automatic closing mechanism and reliable sealing performance effectively prevent medium backflow, safeguarding the safety of personnel and equipment.

  • Easy Operation: No external power is required; fluid pressure automatically drives the valve disc to open and close, enabling simple operation.

  • Convenient Installation and Maintenance: The swing-type connection simplifies the installation process and also facilitates maintenance and overhaul, reducing maintenance costs.

  • Wide Applicability: Multiple material options and a broad range of pressure and temperature make it adaptable to various complex working conditions and medium characteristics.
