Pressurized fluid apparatus including a pressurized fluid container, a pipe arranged for flow therethrough of the pressurized fluid into the container, a valve operatively connected to an end of the pipe disposed in the container, and a float attached to the valve, wherein the float is buoyed generally upwards by the pressurized fluid filling the container, such that when the float has been moved a predetermined amount, the float closes the valve and substantially stops flow of the pressurized fluid into the container, and wherein the float is insertable through an upper opening of the container, and wherein the valve is rotatably attached to the pipe, the valve being closed by an angular upward movement of the float, characterized by the valve including a tube with a longitudinal bore having a longitudinal axis formed therein, and a piston slidingly disposed in the tube, wherein only when the float is generally perpendicular to the longitudinal axis, the piston sealingly abuts an internal end face of the tube, thereby closing the valve.
