Abstract
A check valve which includes a valve body having an inlet end, an outlet end and a flow bore that extends between the inlet and outlet ends; a valve seat which is positioned across the flow bore; and a flapper which is configured to seal against the valve seat. The flapper is connected to or formed integrally with a pivot pin and is pivotable between a closed position in which the flapper is positioned against the valve seat and an open position in which the flapper is displaced from the valve seat. The pivot pin has opposite first and second ends, each of which is supported in a corresponding resilient bushing which is supported in the valve body. The resilient bushings allow the flapper to better align with the valve seat when the flapper is in the closed position.
