Abstract: A check valve is provided. The check valve includes a petal pivotably coupled to a hinge to occupy respective open and closed positions in accordance with a pressure differential of a fluid flow across the check valve and a lift generating element coupled to the petal and configured to aerodynamically interact with the fluid flow to generate a lift force on the petal.
