Swing Check Valve

Cast Steel Swing Check Valve Manufacturer: FlowBiz Exports

The FlowBiz Swing Check Valve is an automatic, self-actuating valve designed to prevent flow reversal in piping systems. The valve features a disc mounted on a hinge or shaft that "swings" off the seat to allow forward flow. When the fluid velocity decreases or the flow reverses, gravity and the back-pressure of the media swing the disc back onto the seat, creating a tight seal.

Design Standards & Compliance

FlowBiz valves are manufactured to meet the most stringent global engineering standards:

  • Design Standard: BS 1868 (Steel Check Valves)
  • Pressure/Temp Rating: ASME B16.34
  • Face-to-Face Dimension: ASME B16.10
  • End Flanges: ASME B16.5
  • Testing & Inspection: API 598 (Valve Inspection and Testing)

Key Features & Advantages

  • Low Pressure Drop: The straight-through, full-ported design offers minimal resistance to flow, making it highly efficient for high-volume liquid and gas lines.
  • Bolted Cover Design: Allows for easy internal inspection and maintenance of the hinge and disc assembly without removing the valve from the pipeline.
  • Internally Mounted Hinge: For sizes $2"$ to $12"$, the hinge is mounted internally, eliminating the need for body penetrations and reducing the risk of external leakage.
  • Extreme Thermal Resistance: Capable of operating in environments up to $816^{\circ}\text{C}$, ideal for superheated steam and refinery process lines.
  • Robust Sealing: Utilizes high-grade Graphite gaskets to ensure integrity under fluctuating thermal and pressure cycles.
