A flexible check valve is a one-way flow control device made from elastic materials such as rubber or elastomer. It allows fluid to pass freely in one direction while automatically closing to prevent backflow when pressure reverses. Flexible check valves are widely used in wastewater, drainage, irrigation, and industrial piping systems due to their simple structure, corrosion resistance, quiet operation, and low maintenance requirements
