ABSTRACT:
There is disclosed a gate valve having a fabricated, box-like body in which the gate is movable, and hubs welded to and extending within opposite walls of the body to mount seats on their inner ends to engage the gate. Laterally disposed, generally "C"-shaped, rigid reinforcing flanges have inner edges which are spaced from but extend closely about the opposite side walls and adjacent ends of the front walls of the body on opposite sides of the valve body. One end edge of each flange is welded to one hub and the other end edge thereof is welded to the other hub, whereby the flange functions as an eccentrically loaded tension member. A conduit connects to and extends outwardly from the outer end of each hub to enable the valve to be connected in a line, and each such conduit is thinner than the hub to which it is connected.
