A moveable flapper is located within the check valve between the valve body sections and is movable between a between a closed state and an opened state, and vice versa, to effect the selective closing and opening of the ports. The valve body sections are configured to be rotated 180 degrees with respect to each other so that they are in an either an axially aligned state or in an elbow state. The interface between the passageways is formed by two elliptical shaped planar surfaces, each extending at an angle of 45 degrees to the central axis of the associated passageway. The valve also includes a pressure relief assembly.
