ABSTRACT:
A flow valve for mating with a fluid coupling of the type comprising a cylindrical body and a plurality of circumferentially spaced latches. The flow valve comprises a generally cylindrical valve housing and an annular flange adjacent one end of the valve housing. The flange is mounted to the valve housing such that the flange is rotatable to facilitate repositioning of the flange to distribute wear on the flange caused by the circumferentially spaced latches of the fluid coupling. In a preferred embodiment, the flange is symmetric and the flange and the valve housing each comprise a predetermined pattern of holes for receiving fasteners for mounting the flange to the valve housing. After a period of use, the fasteners can be removed and the flange repositioned, or reversed, to distribute wear to other locations on the flange.
