Patent ID: 7708028

Claim:
A system for controlling the discharge of pressurized fluids from the outlet of a pressurized tank containing hydridic or halidic compounds, the system comprising: a tank for holding a pressurized fluid in a gaseous or partially gaseous phase; a port body for communication with the outlet of the pressurized tank defining a fluid discharge path; a valve element fixed in or upstream of the port body and adapted to movement between a sealing position that blocks fluid flow through the fluid discharge path and an open position that permits fluid along the fluid path; a bellows chamber disposed within a housing downstream of the valve element, wherein the bellows chamber is charged and sealed to a pressure ranging from greater than about 14.7 psia to about 50 psia, having bellows made of a age hardened inconel material; and said bellows chamber communicates with a portion of the fluid discharge path downstream of the valve element to move the valve element to the open position when communication with the discharge path produces a vacuum condition within the housing.
