Duckbill Check Valves

Duckbill valves are unique, one-piece, elastomeric components that act as backflow prevention devices or one-way valves or check valves. They have elastomeric lips in the shape of a duckbill which prevent backflow and allow forward 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.
