Liquid flow air control non return Silicone One way check valve
One-way valve components are used to create a unidirectional flow in a device. They are in fact elastomeric sealing elements that allow forward flow and prevent backflow. There are different designs. If you like low opening pressure and ease of assembly then the first choice would be a duckbill valve. If you need a certain cracking pressure or a low-pressure drop at higher flows then an umbrella valve would be our recommendation.

Medical Grade Air flow Silicone Umbrelle Check Valve
Silicone Umbrella valves are elastomeric valve components that have a diaphragm shaped sealing disk or an umbrella shape if you like. These elastomeric components are used as sealing elements in backflow prevention devices or one-way valves or check valves, in vent valves or pressure relief valves and in metering valves. When mounted in a seat, the convex diaphragm flattens out against the valve seat and absorbs a certain amount of seat irregularities and creates a certain sealing force. The umbrella valve will allow forward flow once the head pressure creates enough force to lift the convex diaphragm from the seat and so it will allow flow at a predetermined pressure in one way and prevent back flow immediately in the opposite way.
