   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.
