   What is a duckbill valve?

   • While some check valve designs are prone to corrosion, fouling, and erosion, the duckbill type is made of robust rubber or other elastomeric material. The duckbill valve is a flexible one-piece sleeve in the shape of a duckbill that disintegrates at the cracking pressure and closes again below this threshold.

   How does a duckbill check valve work?

   • This process occurs seamlessly without external intervention, making duckbill check valves inherently passive and low-maintenance components. As the fluid flow subsides or attempts to reverse, the elasticity of the valve material ensures that the slit reverts to its closed position, effectively sealing off the passage.

   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.
