Abstract:
The gas flow restrictor includes a cylindrical body having threads for mounting the body in a gas flow line. One end of the body is closed and includes a plurality of angularly spaced plugs having a predefined diameter that may be the same or different from each other. Each plug is selectively removable from a correspondingly sized orifice, singly or in combination, to set the desired gas flow and thereby reduce incoming gas flow pressure through the lines.
