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.

   • 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.
