A pair of serially connected electrically operated computer controlled gas valves combine with a pressure sensor to output pressure regulated low pressure gas dispensed from a high pressure gas source and define a pressure regulation system of relatively simple construction, great versatility and of heretofore unknown flexibility, well suited to remote control. The computer controlled valve controller selectively operates the valves in any and all of three operational modes, including the familiar Bang-Bang mode in which both valves operate simultaneousl...
[ What is claimed is:] [19.] A gas pressure regulator comprising in combination:first and second electromagnetic gas valves, each having a gas inlet and a gas outlet and each said first and second electromagnetic gas valves being operable, when energized, from a closed condition to an open condition;said gas outlet of said first electromagnetic gas valve being connected to the gas inlet of said second electromagnetic gas valve to place said electromagnetic gas valves in series gas transmission relationship between said gas inlet of said first gas valve a...
