The present invention provides a pressure regulator comprising a housing including an support surface, a moveable pressure boundary member extending across the internal surface of the housing to define a high pressure chamber and a low pressure chamber, a pintle valve, including a pintle stem and a pintle nut, the pintle stem extending through the diaphragm plate and carrying the pintle nut, the pintle nut being disposed in the low pressure chamber side of the housing, and a resilient member interposed between the pintle nut and the diaphragm plate. The present invention further provides a pressure regulator comprising: a housing including an internal surface, a diaphragm plate, a diaphragm, extending from the diaphragm plate and secured to the internal surface of the housing to define a high pressure chamber and a low pressure chamber, characterized by first and second side surfaces, wherein the first side surface faces the high pressure chamber and wherein the second side surface faces the low pressure chamber, a spring chamber disposed in the low pressure chamber, defined by sidewalls characterized by a surface substantially parallel to the axis of the diaphragm and terminating at an edge proximate to and spaced from the diaphragm to define a lower section and further characterized by a perimeter, and an annulus also disposed in the low pressure chamber and about the perimeter of the lower section of the spring chamber and partly defined by a support surface extending radially and outwardly from the edge of the sidewalls of the spring chambers, wherein the diaphragm plate is characterized by first and second positions, wherein in the first position, the diaphragm plate is spaced from the support surface of the housing, and wherein in the second position, the diaphragm plate is disposed in contact with the support surface of the housing.
