Ball Valve - Heat and Food Safety Question

[thebigvoodoo]

Here are the specifications for the ball valve I am using that separates my column from my Liebig condenser: http://www.mastewart.com/Drawings/MAS/B ... -12-17.pdf

As far as I can tell all the materials are food safe at standard still operating temperatures. I just wanted to run this by the experts here at Home Distiller in case I'm missing something.

(In case you're wondering why I have a valve between my condenser and my column, I'm building a hybrid still and so have a reflux portion that has a liquid management system attached to it. When I'm operating the still in reflux mode I can shut the system off from my Leibig condenser.)

The body is made of brass. So you will need to pickle it. Do a search for brass pickling. Now are you talking a LM VM combo? Or a LM pot still combo? The LM VM would be fine. The LM pot could pose problems. Like the LM needs to be vented to atmosphere above the reflux condenser. Where the pot still should not be vented to atmosphere before the output. If there is a vent on a pot still dangerous alcohol vapors could escape out the vent.
