A scupper valve includes a frame and a rigid flapper coupled to the frame. The rigid flapper is configured to swing relative to the rigid frame between an open and closed position. A flexible annular seal defines a centrally-disposed circular opening and a first annular projection that surrounds the centrally-disposed opening. The rigid flapper, in the closed position, contacts a distal edge of the first annular projection to create a circular line contact that restricts or prevents fluid flow through the centrally-disposed circular opening in the flexible annular seal. A rigid annular backplate is adjacent to and in direct physical contact with an annular surface of the flexible seal on a side of the flexible seal opposite the rigid flapper.
