Orifice?

Does this serve as a needle valve and an orifice? If so, how do I know if it's high pressure or low?View attachment ImageUploadedByHome Brew1472763214.811841.jpg

Sure looks like a needle valve.
Not sure if that'd work as an orifice, however, as the bore shown looks way too wide for both propane and natural gas.

What's the bore on the other end look like?

Cheers!

Same size on the other. I hadn't seen a low pressure orifice so I wasn't sure how large it was.
