1. A regulating valve for a gas cooking appliance, the regulating valve comprising:
a valve body with an inlet conduit through which gas is supplied, an outlet conduit and an inner cavity in fluid communication with the inlet conduit, the valve body including an internal through hole that fluidly communicates the inner cavity with the outlet conduit:
a rotating disc arranged in the inner cavity of the valve body, the rotating disc including a first plurality of connecting holes arranged in an angular path and configured to regulate a plurality of intermediate gas flow rates through the regulating valve, the rotating disc rotatable between a plurality of angular positions corresponding to the plurality of intermediates flow rates to cause a positioning of at least three of the first plurality of connecting holes to overlap with the inner through hole of the valve body to regulate the plurality of intermediate gas flow rates between the inner cavity and the outlet conduit, the first plurality of connecting holes including a main series of connecting holes consecutively arranged in order of increasing size along the angular path in a direction corresponding to an increase in gas flow, the first plurality of connecting holes further including a plurality of first intercalated holes with one of the first intercalated holes being positioned between pairs of the main series of connecting holes, each of the pairs of the main series of connecting holes comprising successive first and second holes, the first hole preceding the second hole and being smaller in size than the second hole, each of the first intercalating holes having a size that is smaller than the nearest preceding first hole in the pairs of the main series of connecting holes, the rotating disc includes an off position wherein none of the first plurality of connecting holes overlap with the inner through hole of the valve body, the first plurality of connecting holes further comprising a plurality of second intercalated holes with one of the second intercalated holes also being positioned between the pairs of the main series of connecting holes, the plurality of angular positions corresponding to the plurality of intermediates flow rates including a first intermediate gas flow position and a second intermediate gas flow position, the rotating disc rotatable to a transitional position between the first and second intermediate gas flow positions wherein one of each of the main series of connecting holes and one of the first intercalated holes fully overlaps with the inner through hole of the valve body and two of the plurality of second intercalating holes only partially overlap with the inner through hole of the valve body.
