1. • Flexible sleeve shaped like a duck’s beak

     • The duckbill check valve is a flexible sleeve shaped like a duck’s beak. It allows forward flow of water with positive head differential pressure which progressively opens the valve as flow increases. Duckbill check valves consistently provide the tightest seal for preventing backflow.

   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.
