ABSTRACT:
A float valve having a pair of valve plugs mounted on a single valve stem employing a flexible or pivoting couple between the float and the valve stem that allows the float to tilt and move laterally with respect to the axis of movement of the valve stem without affecting the alignment of the valve plugs in relation to their respective valve outlets. This flexible couple might also allow for some free movement of the float in the direction of the axis of movement of the valve stem. In one embodiment the valve plugs have ported sealing surfaces that allow gradual starting and stopping of the flow of fluid through the valve outlets.
