A regulating shut off valve for a high pressure gas bottle useful when the pressure within the bottle can be higher than the maximum safe working pressure of a pneumatic system connected thereto. The valve is sized to fit under a standard protective cap when installed on a gas bottle. The valve includes a poppet assembly with a needle that acts with a valve seat so that the poppet assembly can be screwed open to allow gas to pass from the bottle to the system or screwed closed against the seat. The valve seat, which is operatively connected to a spring loaded piston to which system pressure is applied, is responsive to the maximum safe working pressure of the system. When such pressure is present, the valve seat moves against the needle to regulate flow.
