Duckbill valves are one-piece elastomeric components that act as backflow prevention devices or one-way valves. their lips in the shape of a duckbill prevent backflow and allow forward flow. there are different kinds of duckbill valves including slip-over style, jacket style, flanged style, in-line style duckbill valves. Duckbill valves are installed easily and they can take on low opening pressure - immediate free flow.
The main advantage of duckbill valves over other types of one-way valves is that duckbill valves are self-contained i.e. the critical sealing function is an integral part of the one-piece elastomeric component as opposed to valves where a sealing element has to engage with a smooth seat surface to form a seal.
Therefore duckbill valves are easily incorporated and assembled into a wide variety of devices without the hassle or problems associated with the surface finish quality of mating seats and/or complex assembly processes.
