A filling valve for a pressurized fluid container, including a valve body with a longitudinal bore and a side opening formed therein, a sealing assembly slidingly disposed in the valve body, the sealing assembly being formed with a bore therethrough, a valve lever pivotally attached to a portion of the valve body, the sealing, assembly including a jutting portion which protrudes in a direction generally away from a bottom portion of the valve body, a float arm attached to the valve lever, and a float mounted on the float arm, wherein when the float is positioned at a generally obtuse angle with respect to a longitudinal axis of the valve body, the jutting portion of the sealing assembly is raised and supported by the valve lever, such that the sealing assembly is raised and does not block the side opening thereby permitting fluid flow through the side opening, and wherein when the float is sufficiently buoyed by a fluid, the float arm swings upwards and the jutting portion of the sealing assembly is no longer supported by the valve lever and the sealing assembly moves downwards and blocks the side opening, thereby preventing fluid flow through the side opening.
