1. A control valve for a gas burner, the control valve defining a transverse direction and a lateral direction perpendicular to the transverse direction, the control valve comprising:
a valve body defining an inlet conduit and a valve chamber, the inlet conduit having a width along the lateral direction and a non-circular shape in a plane that is perpendicular to the transverse direction; and a plug positioned within the valve chamber of the valve body, the plug defining a slot on an outer surface of the plug, the slot including a width along the lateral direction, the plug also defining a flow chamber within the plug, the plug further defining an aperture that has a non-circular shape, includes a width along the lateral direction, and extends perpendicular to the lateral direction between the slot of the plug and the flow chamber of the plug, the plug configured to rotate about the lateral direction within the valve chamber of the valve body in order adjust a position of the slot of the plug relative to the inlet conduit of the valve body, wherein the slot extends between a first end portion and a second end portion on the outer surface of the plug, a height of the slot decreasing from the first end portion of the slot to the second end portion of the slot, wherein the width of the inlet conduit, the width of the slot, and the width of the aperture are about equal, and wherein a cross-sectional area of the inlet conduit is constant along the transverse direction. |
