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.

A portable, refrigerant recycle/recovery/charging system comprising: a storage tank; a low pressure refrigeration system; and a housing. The housing includes liquid, vapor, pump and condenser sections. The liquid section has a liquid inlet, a liquid outlet and a liquid conduit connecting the liquid inlet and the liquid outlet where the liquid conduit includes a liquid flow control device and a liquid condition sensing device. The vapor section has a vapor inlet, a vapor outlet, and a vapor conduit connecting the vapor inlet and the vapor outlet where the vapor conduit includes a vapor flow control device and a vapor condition sensing device. The pump section has a pump inlet, a pump outlet, and a pump conduit connecting the pump inlet and the pump outlet where the pump conduit includes a pump. The condensing section has a condensing inlet, a condensing outlet, and a condensing conduit connecting the condensing inlet and the condensing outlet where the condensing conduit includes a condenser.
