Tideflex Duckbill Check Valves are reliable check valves to prevent unwanted backflow in outfall applications. The flexibility of Tideflex allows the valve to compress around trapped solids, providing a better seal than flapgates. The curved bill returns to a closed position every time, achieving the tightest possible seal to prevent backflow, particularly at low flow rates. This check valve has a record of maintenance-free backflow prevention.
