The manufacturer creates the orifice in a gas valve by basically making a hole with a drill, and drill sizes are numbered from 75 to 1. The smallest hole — which is a little less than 3/64 inches — is 75, and the largest — 1/4 inch — is 1.

The Beta Ratio is the ratio between the line inner diameter to bore size of the orifice. The flow coefficient is found to be stable between beta ratio of 0.2 to 0.7 below which the uncertainity in flow measurement increases. An orifice plate beta ratio of 0.6 means that the orifice plate bore diameter is 60% of the pipe internal diameter.
LP Grills orifices that are 26″-32″ Tube burners and side burners uses – roughly #55 =1.33mm hole LP Grills orifices that are 26″-32″ Cast burners uses – roughly #56 = 1.2mm hole Back burners average between #59 = 1.05mm or #60 = 1.0mm Natural Gas Grills –
The capacities of these orifices are the same as the standard orifice of the same size. The 1800C Series pressure regulators are designed to control natural gas,. This easy-to-use calculator will help you calculate the orifice size of your valve. All other orifice sizes shown are available as individual items, see orifice chart below for part numbers.

Drill bit numbers and sizes have an inverse relationship. The larger the number, the smaller the drill bit. (Orifice hole size will be larger for natural gas supply models than propane because of the lower natural gas operating pressure).
