The valve assembly includes a body having a communication passage with an inlet and an outlet and a combustion chamber having a propellant and one or more openings, an igniter in communication with the propellant, and a valve means movable within the body. The igniter is adapted to ignite the propellant to provide a force to move the valve means from a closed position to an open position. The valve means has a first restricting element to restrict and permit passage of a pressurized gas through the outlet and a second restricting element to restrict and permit passage of heat from the burned propellant through the openings of the body, wherein the heat/gases cause a pressurized gas within the receptacle to expand causing the gas to quickly expunge from the receptacle. A biasing means may be used with the valve means to retain the valve means in the closed position,
