Related Product Features:
  • Flange duckbill valve with a unique, flexible, non-mechanical design resembling a duck's bill.
  • Made from durable elastomeric materials like Neoprene, EPDM, or Viton for seawater corrosion resistance.
  • Operates passively with no need for external power, relying on fluid pressure differential.
  • Low-pressure start-up at 0.1Bar, ensuring efficient flow with minimal head loss.
  • Prevents backflow effectively by sealing tightly under reverse pressure.
  • Available in various sizes from DN50 to DN1200 to fit different pipeline requirements.
  • Ideal for wastewater treatment, stormwater outfall systems, and flood control applications.
  • Export-grade quality assurance for reliable performance in demanding marine environments.
Faqs:
  • What materials are used in the Marine Flange Duckbill Valve?
    The valve is made from flexible elastomeric materials such as Neoprene, EPDM, Natural Rubber, Buna-N, or Viton, ensuring durability and seawater corrosion resistance.
  • How does the flange duckbill valve prevent backflow?
    When forward flow stops or reverse pressure occurs, the flexible lips of the duckbill squeeze tightly together, creating a seal that prevents backflow without any mechanical intervention.
  • What are the typical applications for this valve?
    This valve is widely used in wastewater treatment plants, stormwater outfall systems, flood control, and submerged outfall diffusers, ensuring reliable one-way flow in demanding environments.
