A rubber duckbill check valve, also known as a rubber flapper check valve, is a type of check valve that is commonly used to prevent backflow in pipes and systems. It consists of a rubber duckbill shaped valve that opens to allow fluid to flow through in one direction, and closes to prevent backflow. The rubber material allows for a tight seal, ensuring that no fluid is able to pass through in the reverse direction.
Rubber duckbill check valves are often used in applications where backflow can cause damage or contamination, such as sewage systems, stormwater drainage systems, and irrigation systems.
