Valves for Propane Trim on Brew Cart?
« on: July 22, 2010, 12:18:20 pm »
I'm finally starting the build on my brew cart.  It will have one propane tank attached to a manifold feeding two of these burners.   I'll mostly have just one burner running at a time, but I need to be able to trim both burners independently - mainly for convenience.  I'm not automating anything, so I don't need solenoid-type gas valves - just something hand-operated.

My first thought is to use the 1/4-turn valves used as shut-offs for gas stoves and other gas appliances - but I'd like fairly good control, and I'm not sure whether a 1/4-turn valve would provide that.  What kind of valves have others used?  Needle valves?  1/4-turn ball valves?  Other suggestions?  Any suggestion on pipe and valve size for the manifold?  I'm thinking 3/8" or 1/2" brass or black pipe should be fine.

I have a very old Sabco Brew Magic on which I recently upgraded the burners.
It runs the propane through the frame and has 1/4 turn ball valves (I think they're ball valves) on 3/8 inch black pipe to each burner, just like you mentioned.  Works very well.
The most difficult thing to find was the combination of fittings to go from the orifice tube on the burners (3/8 flare or something very similar) to the black pipe (3/8 pipe thread).

Bayou Classic sells HP Orifice that have 3/8" MFlare ends that would work.

I'm using 1/2" gas ball valves on black pipe from Home Depot for my "BREWTOWER".  Works great, even with two burners at once.
