A valve stem for a pressurized valve assembly. The valve stem has an open top portion, a closed bottom portion, at least one primary radial opening, and a valve stem longitudinal passageway between the open top portion and the at least one primary radial opening. A conduit extends from the valve stem at an angle relative to the valve stem longitudinal passageway, proximate to the open top portion. The conduit provides a flowpath between the valve stem longitudinal passageway at a conduit first end and a dispensing opening at a conduit second end.
