Multi-stage fluid regulators are described. An example fluid regulator (200) includes a regulator body (202) having an inlet (204) in fluid communication with a source of pressurized fluid. A first fluid valve (208) 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 (246) is disposed within the regulator body and coupled to the inlet and, via a passageway (248), 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. |
