Abstract
Multi-stage fluid regulators are described. An example fluid regulator includes a regulator body having an inlet in fluid communication with a source of pressurized fluid. A first fluid valve is disposed within the regulator body and coupled to the inlet to regulate a pressure of the pressurized fluid at the inlet. A second fluid valve is disposed within the regulator body and coupled to the inlet and, via a passageway, to the first fluid valve. The second fluid valve is to cause a fluid pressure in the passageway to be regulated to a predetermined portion of the pressure of the pressurized fluid at the inlet.
