1. A fluid control valve, comprising:
a cover portion including a first inner surface;
a body portion to couple with the cover portion, the body portion including:
a second inner surface, the first inner surface and the second inner surface defining a chamber between an inlet and an outlet, the inlet and the outlet defining an axis;
a seat member aligned along a plane perpendicular to the axis; and
one or more members disposed about the seat member, the one or more members having an arc shape;
a diaphragm disposed in the chamber between the cover portion and the body portion, the diaphragm to move between a first position in which the diaphragm is spaced from the seat member to allow fluid flow between the inlet and the outlet and a second position in which the diaphragm conforms to and seals the seat member, the diaphragm biased to the second position without additional biasing devices to bias the diaphragm from the first position to the second position; and
an inversion inhibitor extending from the cover portion to prevent the diaphragm from fully inverting while the diaphragm conforms to first inner surface of the cover portion.
