Guide To Silicone Duckbill Valves

Aug. 16, 2023

Silicone duckbill valves, often referred to as one-way check valves or non-return valves, which are designed to allow the flow of fluids in one direction while preventing backflow. Their unique construction consists of a flexible, elastomeric material – typically silicone – shaped like a duck's bill. This ingenious design enables the silicone duckbill valve to open and allow fluid or air passage when there is sufficient pressure, and automatically close when the pressure diminishes, thus preventing any reverse flow.
