Structural composition

The composition of the duckbill valve mainly consists of elastic neoprene and man-made fibers, which are specially processed.

This structure makes the duckbill valve close under its own elastic action when there is no internal pressure; As the internal pressure gradually increases, the outlet gradually increases, thus keeping the liquid discharged at high flow rates.

This design allows the duckbill valve to be widely used in a variety of piping systems, as it effectively prevents the back flow of liquids while keeping the fluid flowing smoothly.
