Abstract
A check valve includes a valve body, a valve seat positioned in the passageway of the valve body dividing the passageway into two chambers and a clapper assembly, which is pivotally mounted to the valve seat. The valve seat has a valve seat body and an opening through said valve seat body. The clapper assembly is pivotally mounted to the valve seat by a hinge pin and biased to close the opening of the valve seat body to thereby block the flow of fluid through said passageway. Further, the hinge pin is captured between portions of the valve body to thereby retain the clapper assembly at the valve seat.
