Abstract:
A modified vacuum actuated valve assembly and sealing mechanism is provided for improved sub-atmospheric flow stability characterized by the absence of delivery pressure spikes and flow excursions. The valve assembly includes a non-stationary thermoplastic seat and a stabber. The stabber is characterized by a top portion having a circular periphery designed to mechanically engage and disengage with an inner sealing surface of the thermoplastic seat. The sealing surface is coined to eliminate surface irregularities contained therein, thereby producing a relatively smooth coined mating inner sealing surface for the circular top portion of the stabber. The valve assembly also includes a modified bellows capable of fine tuning the delivery pressure of the valve assembly.

Claim (Index 9):
The vacuum-actuated valve assembly ( 10 ) of  claim 1 , wherein said fluid is a gas selected from the gaseous hydrides arsine (AsH 3 ), phosphine (PH 3 ), diborane (B2H6), hydrogen (H2) and halide boron triflouride (BF 3 ), silicon tetrafluoride (SiF 4 ), germanium tetrafluoride (GeF4), Selenium hexafluoride (SeF6), phosphorus trifluoride (PF3) and oxides carbon dioxide (CO2) and carbon monoxide (CO) as sources of arsenic (As), phosphorus (P), boron (B), silicon (Si) germanium (Ge), selenium and carbon.
