   What is a duckbill check valve?

   • 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. Any reverse differential pressure closes the valve tightly, preventing backflow. Duckbill check valves are non-mechanical, require no maintenance, and do not slam when closed.

   How does a duckbill valve work?

   • Conversely, the design of the duckbill valve is such that any flow that moves in the opposite direction causes the two halves to close together. This prevents the passage of any liquid and generally the higher the reverse pressure the tighter the valve closure.

    Jun 3, 2021 · 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.
