1. • • Composed primarily of elastomeric materials such as rubber or silicone, the valve features a tapered bill-like structure with a thin slit or orifice at one end. This unique configuration enables fluid flow in one direction while obstructing reverse flow, akin to the behaviour of a duck's bill when feeding.

   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.

   Does a duckbill valve open or close?

   • The flexible Rubber Duckbill Valve is normally closed but will open with very minimal head pressure, always providing maximum flow with a minimal pressure drop across the valve. Conventional Flap-Gate Check valves and other check valves are mechanical and have metal components which are commonly known to malfunction, rust and seize.

   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.

   What is the difference between a duckbill check valve and a ball valve?

   • Unlike duck-bill check valves, mechanical disc and ball valves can be expensive and difficult to maintain. As they age mechanical check valves deteriorate and may vibrate or emit noises, components can even fail and be lost from the valve and into the connected pipework.
