ABSTRACT:
A device for isolating and containing gas reactive materials includes a novel valve arrangement that is actuatable in conjunction with the movement of a pre-loaded metal diaphragm. The valve is situated in a housing having an inlet and an outlet fitting, a seat for the diaphragm and a metal tube in contact with the diaphragm to provide fluid communication between the housing and the gas supply to that the pre-loaded diaphragm is opened upon the connection of the gas supply to allow gas flow to the gas reactive material disposed within the housing. The pre-loaded diaphragm force is sufficient to form a fluid tight seal when the device is disconnected from a gas supply line therby sealing the interior of the device from the surrounding enviroment.
