A metallic gas pressure regulator includes a spring casing and a lower casing, sandwiching a diaphragm. The lower casing has axially aligned inlet and outlet ports. A one piece plastic cam stem and relief seat is mounted for movement with the diaphragm and includes a cam surface engaging a movable plastic disk holder. The disk holder is movable within a plastic orifice tube that supports a plastic valve seat. The orifice tube has a removable plastic boost end cap for providing a boost action to the diaphragm. A pressure relief mechanism is incorporated within the upper portion of the diaphragm. A metal disk is affixed in the inlet and includes a flow restricting hole and a flow diverter for directing flow toward the pressure relief mechanism in the event of destruction of the plastic orifice tube.
