Abstract: An apparatus for providing a pressurized gas inline valve assembly incorporating a check valve to maintain pressure above a selectable psi and a ball valve for selectively shutting off gas flow. The apparatus is preferably positioned approximate the gas source in a beverage dispensing system that uses carbon dioxide for carbonation, preservative and propellant. Preferably, the apparatus is designed to maintain the system pressure above the threshold pressure that when below said threshold pressure the carbon dioxide would revert to its inoperative dry ice solid state as opposed to its operative liquid state.
