A manually operated valve and a pressure regulator are provided in the first passageway exterior of the vessel. In one embodiment the control body has a second passageway opening through a relief device to the vessel interior and to the ambient atmosphere while in a second embodiment a relief device is provided exterior of the vessel and opens to the first passageway. A main valve is provided in the first passageway and is moved to an open condition when a solenoid is energized.
