I am currently using a Camp Chef Pro30 burner (1psi regulartor, I guess) and was pretty happy with the construction and use of it. The gas flow control knob is ok and my needed flame is usually quite small. I have Dwyer 6Kpa max pressure meter coming and is looking for better needle valve to fine tune flame. I read good thing about this Parker valve:

The 3/8" NPT is perfect for my setup, but it is not available.

I would appreciate any alternative that may give consistent and steady flame control. Thanks!!

Thanks a lot for the direction! For some reason, HB does not email me even I subscribe the thread.

And if I may be picky, the only issue is that it is 1/4" instead of 3/8" so additional adapters will be needed.

I was checking with this one:

I would appreciate heads-up if it is not suitable. Thanks!!

I talked to the guy at ISM (selling the BFR-6F-B) and he is not 100% sure that the valve can be used for propane safely. I would appreciate some suggestion on how to choose a safe valve to use.

I was looking for an answer to the same question for awhile until I saw an image on this page: https://millcityroasters.com/shop/coffe ... e-roaster/ Image.

A quick search on ebay shows this https://www.ebay.com/itm/1-4-High-Press ... 1330765836.

I plan to test this valve on my Cormorant which is in the same capacity range as the 1/2lb North on the link above.

Btw, you can get flare fittings here: https://www.amazon.com/gp/product/B003RW4IWE/

Just found this one.

It seems to be promising, too.

Not that big a deal. 3/8 to 1/4" adapters and a couple of 1/4" close nipples.

I have the same Parker valve in 1/2" on my big roaster. It retails for $187. The 3/8" is probably $140. $47 for the 1/4" plus a couple of adapters is an inexpensive way to do it

Unless you grab this one off eBay: https://www.ebay.com/itm/Parker-6M-V6LR ... 7830!US!-1

I got the Parker needle valve and it does work very nicely and smoothly for flame control. In conjunction with the Parker 15"wc pressure gauge I got lots of resolution. Thanks to Alan for such a great suggestion!
