Medical grade Non return Silicone rubber duckbill check valve for manual resuscitator
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.

Silicone 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.

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