The rubber Duckbill check valve is all rubber reinforced. It consists in an elastomer sleeve flattened in one end. The Duckbill valve can only be opened when the forward flow lifts the sealing flattened side of the sleeve that, otherwise its natural position is to be closed.
Duck Bill Valves and Umbrella Valves have very similar functions. Duck Bill Valves and Umbrella Valves are one way check valves that open and close at low pressure. Duck Bill valves are often placed at the end of an orifice. As pressure is applied, the end that looks like a Duck Bill opens, allowing for the media to pass through.
A check valve, clack valve, nonreturn valve, reflux valve, or oneway valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.. Check valves are twoport valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications.3

The Series 700 ProFlex rubber duckbill check valves provide backflow protection from occurrences including Sewage slurries. Outfalls to ocean fronts from heavy rainfall activity. Land erosion due to back flow conditions. Invasion of saltwater to freshwater pond.
A valve to prevent gastric reflux or leakage through the vent lumen of a doublelumened nasogastric tube. The valve allows the passage of air into the vent lumen when atmospheric pressure exceeds stomach pressure. When stomach pressure exceeds atmospheric pressure the valve prevents flow of fluids through the tube.
