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 prevents backflow and allows 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.

Application            

Duckbill valves are available in various elastomeric material, including medical and food-grade silicone and hydrocarbon-resistant fluoro silicone rubber to handle a broad range of media and temperatures.


Duckbill valves have been around for many years. Their versatile features have made them first choice in a broad number of applications:


* From long-term service in harsh environments such as in durable chemical pumps to the high-volume use in disposable intravenous fluid delivery sets.


* From one-way valves used in automotive fuel pumps to delicate valves used in tubing circuits for heart surgery, for soap dispensers, coffee makers, anti-siphoning valves in showerheads, and toys.
