Silicone Air Duckbill Valve

silicone air 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.

Silicone Air Duckbill Valve
silicone air 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 
silicone air  duckbill  valves over other types of check valves is that one-way 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 
silicone air  duckbill 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.


Silicone air duckbill valves are used for controlling the direction of flow of a fluid. Designs can include umbrella valves, duckbill valves,  Belleville Valves and diaphragm valves etc.

Silicone air duckbill valves can be designed to provide the customer's required head loss and flow rate for particular applications.

A range of materials and designs are available to handle different fluids and service conditions.
