A fluid pressure regulating apparatus is provided. The apparatus includes a chamber having a first bore diameter, a second bore diameter, a fluid inlet for receiving fluid at an unregulated pressure, and a fluid outlet for discharging fluid at a regulated pressure. A shuttle assembly is located in the chamber, the shuttle assembly including a valve that is in fluid communication with both the fluid inlet and the fluid outlet, and a first sealing member located at an upper portion of the shuttle assembly and a second sealing member located at a lower portion of the shuttle assembly. An unregulated pressure zone communicates with the fluid inlet, a regulated pressure zone communicates with the fluid outlet and a fluid pressure control zone communicates with a portion of the shuttle assembly, the fluid pressure control zone controlling the regulated pressure at the fluid outlet.
