Claim:
A fluid regulator, comprising: a housing; a flange with a first radius defining an inner portion of the flange and a second radius greater than the first radius that defines a mounting envelope of the fluid regulator; wherein the flange includes a plurality of protrusions that are circumferentially spaced so that first and second ones of the plurality of protrusions are separated by a first circumferential spacing and the second one and a third one of the plurality of protrusions are separated by a second circumferential spacing greater than the first circumferential spacing; wherein each of the plurality of protrusions includes at least one aperture configured to receive a fastener such that more than four apertures are provided by the flange; a valve having a seat, a valve disc and a stem coupled to the valve disc; a valve guide that holds the stem to maintain a sealing surface of the valve disc in a substantially coplanar relationship to the seat; and a lever having a first end coupled to the stem and a second end coupled to a diaphragm disposed within the fluid regulator, wherein the lever is coupled to the stem to apply a force component to the stem in a direction that is substantially perpendicular to the longitudinal axis of the stem.
