A pressure regulator (500) is provided. The pressure regulator (500) comprises a housing (503), a fluid inlet (508) to receive a pressurized fluid at an inlet pressure, and a fluid outlet (510) to output the pressurized fluid at a regulated pressure. The pressure regulator (500) further includes a regulating piston (504) movable within the housing (503) to provide fluid communication between the fluid inlet (508) and the fluid outlet (510). The regulating piston (504) includes a first end (505) comprising a first cross-sectional width (D,) in fluid communication with the fluid inlet (508) and a second end (509) comprising a second cross-sectional width (D2) in fluid communication with the fluid outlet (510). The first and second cross-sectional widths (D15 D2) are sized such that the regulated pressure at the fluid outlet (510) is correlated to the inlet pressure at the fluid inlet (508).
