Detailed Description for Duckbill Valves

Duckbill valves act as backflow prevention devices or one-way valves or check valves. These valves have elastomeric lips in the shape of a duckbill which prevents backflow and permits forward flow. The main advantages of duckbill valves over other type of one-way valves is that duckbill valves are self-contained i.e. the critical sealing function is a vital part of one piece elastomeric component as opposed to valve where a sealing element has to engage with the smooth seat surface to form  a seal.


Therefore duckbill valves are easily integrated and assembled into a wide variety of devices without any hassle associated with the surface finish quality of mating seats and complex assembly processes.
