Abstract of the Disclosure A swing check valve wherein the valve seat, disc and hanger for the disc are in the form of a replaceable cartridge which can be conveniently inserted in and removed from the valve chamber through one end of the valve body. The hanger is sized such that the hinge pin of the disc can move a limited distance in the hanger toward and away from the valve seat to provide a floating disc. A projection is formed on the disc positioned to engage the valve seat when the disc extends at about 90° from the seat. The seal ring in the valve seat is sized to completely fill its receiving groove and the face of the valve seat is recessed at one side of the groove for distortion of the material of the seal ring therein upon closure of the valve. -18-
