    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.

    Flange integral duckbill check valves are offered as direct replacements for ineffective and maintenance ridden flap type check valves, commonly known to seize, rust and bind in unwanted positions. Unlike flap type valves, this rubber check valve will handle large obstructions without jamming or having swing gates binding open.

    Each valve of XINLI is carefully constructed using the finest of engineered materials and some of the most experienced rubber technicians in the industry. All check valves are engineered in precise detail to ensure proper operation and will provide years of unhindered operation and trouble free service.

     All rubber construction resists abrasive slurries
