The Nibco lead-free ductile iron, wafer style check valve is spring actuated which reduces noise for quiet operation. Check valves prevent backflow by automatically closing when fluid reverses direction. The check valve is recommended for automatic fire sprinkler applications where space is a premium. The check valve is wafer style to fit between standard flanges. The twin disc check valve includes renewable bronze discs. Wafer checks may be installed in horizontal positions (or vertical with flow moving up). Nibco check valves are backed by the Nibco 5-years 125% limited warranty.
