forming a first valve body piece having a seal groove;
forming a second valve body piece having an angled edge;
inserting a seal within the seal groove of the first valve body piece; and

wherein radial compression of the seal between the seal groove and the angled edge causes the seal to be retained with the clapper when the first and second valve body pieces are assembled together,
wherein the seal groove includes an end face, facing in a first axial direction in relation to the first valve body piece, and an inner radial face, facing radially inward in relation to the first valve body piece,
wherein the inner radial face is formed on a shoulder extending in the first axial direction away from the end face, and
wherein the shoulder fits into a groove in the seal.
