Flange integral duckbill check valve is a simple, reliable, cost effective method of backflow prevention. The series flange integral duckbill check valve is designed to be installed between two mating flanges. The simple maintenance-free elastomer with a flanged connection eliminates the mechanical parts which can wear and jam in conventional check valves. For installation at the end of pipe line, the valve can be ordered with optional back up flanges.
