How Does a Duckbill Valve Work?
The Duckbill Valve operates via its flexible elastomeric lips, which remain closed under reverse pressure or zero-flow conditions. When forward pressure is applied, the lips open, allowing fluid to pass. Once the pressure drops, the lips seal tightly, preventing backflow. This mechanism eliminates the need for springs or hinges, reducing the risk of failure.
