   What is a duckbill valve?

   • Duckbill Valves are unique, one-piece, elastomeric components that act as backflow prevention devices. Also known as one-way valves or check valves. They have elastomeric edges, or lips, shaped in a way that resembles a duck’s bill (hence their name).

   Why do we need duckbill check valves?

   • Conversely, when the flow ceases or reverses, the slit naturally closes, forming a seal to prevent backflow. This inherent flexibility and self-sealing mechanism make duckbill check valves highly efficient and reliable in controlling fluid movement.

   Do duckbill valves work in stormwater systems?

   • Duckbill valves excel in this environment, ensuring continuous flow and preventing backflow. In stormwater systems, dealing with unpredictable water volumes and debris is a major challenge. Duckbill valves shine here, with their self-cleaning and backflow prevention properties, making them ideal for flood-prone areas.

   What does a duckbill valve look like?

   • A cross-section diagram of a Duckbill valve. The upper pipe depicts normal flow of fluid, while the lower pipe depicts stoppage of backflow. One end of the valve is stretched over the outlet of a supply line, conforming itself to the shape of the line, usually round. The other end, the duckbill, retains its natural flattened shape.
