As a result of my tests, I determined that the Culinary Depot RV47LNG 22 Regulator Natural is a big disappointment. This Industrial and Scientific tool fails to regulate gas flow properly, leading to inconsistent cooking results. The only good thing about it is that it's inexpensive. Avoid this product if you're looking for quality industrial power tools.
The listing is missing the most important piece of information: outlet pressure range in inches of water column. I found out from the Dormont catalog that the "-22" version has a power adjustment range of 2.8 to 5.2 inches of water. I am posting this for the convenience of future buyers. Please note that Dormont is only a distributor and Maxitrol is the actual manufacturer of this regulator.
