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.

   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.

    Jun 13, 2024 · A key characteristic of the duckbill check valve is that it requires no intervention to open or close and operates as a result of a pressure differential across the valve – the pressure from a liquid pushes the two-halves apart allowing the fluid to pass through.
