Abstract
Embodiments of a propane tank valve are provided. In one embodiment, the propane tank valve includes a plug with a tapered portion, the plug moveable between closed and open positions relative to a valve passageway. Upon the plug being in the closed position, the tapered portion of the plug is positioned within the valve passageway. Upon the plug being initially moved from the closed position to the open position, the tapered portion of the plug is sized and configured to initially minimize the gas flow from the valve passageway and through a flow limiting device configured to be coupled to the propane tank valve such that movement of the tapered portion from the closed plug position initially forms a gap between a tapered surface of the tapered portion and an internal surface of the valve passageway.
