Umbrellas and Duckbills

What are umbrellas and duckbills?
Umbrellas and duckbills are precise, small-sized check valves which have characteristic shapes that utilize the deformation and sealing properties of rubber materials. Due to their extremely sensitive response and high reliability, they are used in a wide variety of applications.
