Abstract
A roll-over vapor vent valve is provided having a mounting arrangement for weldably connecting the valve directly onto a polymeric fuel tank. The valve includes a main body casing having at least one inlet for communicating with the internal chamber of the polymeric fuel tank, an outlet for communicating with a point external to the fuel tank and a passageway which communicates with the at least one inlet and the outlet. A controlling mechanism is located within the casing for controlling fluid flow through the passageway between the at least one inlet and the outlet. The mounting arrangement is preferably integral with the main body casing and serves to weldably connect the casing to the polymeric fuel tank. The mounting arrangement may comprise an L-shaped flange which extends out from and encircles a lower portion of the main body casing to define a circumferential weld foot. Alternatively, the L-shaped flange may be bifurcated to define two circumferential weld feet.
