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.

   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.
