Duckbill 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.



 

Other not less important features include:
1)Position independent,
2)Low opening pressure- immediate free flow,
3)Non-tortuous flow path,
4)High flow rate vs. package size,
5)Virtually no internal volume and dead space,
6)Particle compliant,
7)Corrosion resistant,
8)Wear resistant and
9)very cost effective.
