A valve designed to automatically maintain within close limits a predetermined outlet pressure which may be adjustable within a specified range regardless of the higher fluctuating or constant inlet pressure. It is designed for use with compressed gas(es) and various liquids and may include gauges. It may be inline or cartridge (manifold) design. Excludes regulator, pressure, medical gas administration apparatus; regulator, oxygen, barometric continuous flow; regulator, oxygen demand; regulator, oxygen diluter demand; and valve(1), fluid pressure regulating, aircraft.
