Abstract:
1. A system for the controlled storage and dispensing of a hazardous material at sub-atmospheric pressure from a pressurized source vessel, the system comprising: a. a pressurized source vessel having a neck portion and an interior space for holding a hazardous material in either a fluid form or a gas form, the neck portion having a vessel outlet that traverses the neck portion and is in communication with the interior space through which the hazardous material can flow; and b. an integrated valve regulator assembly for the pressurized source vessel, the integrated valve regulator assembly comprising: wherein when a downstream system having a pressure less than one atmosphere is connected to the system via the assembly outlet and the isolation valve is in the opened position, hazardous material in gas form flows from the interior space of the pressurized source vessel through the vessel outlet, along the defined internal passage, through the sub-atmospheric pressure regulator and isolation valve and out the assembly outlet where the hazardous material in gas form is delivered to the point of use at sub-atmospheric pressure and wherein a flow point of the sub-atmospheric pressure regulator can vary depending upon the pressure in the source vessel and the pressure applied to the system via the assembly outlet, said flow point ranging from 50 Torr to 600 Torr.
