Friends,

I know this has been asked ad nauseum before; sorry. I just got my 10 gallon Polarware kettle in the mail. I want to do the full wort boil on propane now. I got some teflon tape for the ball valve that goes on this kettle.

Here is my question: Will the ball valve sanitize itself during the boil? Can I transfer my immersion-cooled wort into my primary without further sanitizing the ball valve?
Thanks,
Dave

the part of the ball valve on the inside of the kettle will be sanitized. the outside in theory would not but it is going to get damn hot. If you are really that worried about it - put some iodaphor in a squirt bottle and squirt the ball valve. I have never sanitized nor squirted the part of the ball valve not in direct contact with boiling wort and not had any problems thus far. but i guess it is not going to hurt.

I have a 10 gal Polarware kettle and a 15 gal Volrath kettle both with ball valves. I've never done anything to sanitize the ball valves. Never had an infection. I would think the heat during the boil would do a great job at sanitizing the ball valves.

Same here . . I use the 10 gallon Polarware for my extract batches and a 15 gallon PW for AG. I've never done anything to sanitize them other than flushing them good with hot water during clean up. Haven't had a problem yet (of course now that I said that, my next batch will probably turn into mushrooms)

Cool.

And also: Do you disassemble the kettle by removing the ball valve after each use?

Dave
Thanks,

The ball valve should get sterilized during the boil. However, I gently recirculate a couple quarts of the boiled wort with a sauce pan then hook it up to the CFC. The recirc gets rid of the small amout of soilds that initially come out and it allows boiling hot wort to contact the entire valve providing additional sanitation. I don't ever remove threaded stainless fittings due to the irritating fact that NPT threads on stainless steel have a tendency to gall. If you must routinly remove stainless fittings, use slow turning and try to mate different alloys such as 304 to 316. See http://www.atlanticfasteners.com/tech_help/tips-020.html
for some interesting tips to avoid thread galling.

Cheers and happy holidays to all,

Me too. Never dissasseble or sanitize the ball valve on my 10 gal. Polarware kettle and have had no problems at all. To counter the galling I simply use some silicone grease on the SS to SS threads where applicable. I remove the thermometer and replace it with a plug when using it for the boil. It's a good idea to just snug the fittings and not overtighten. It's not necessary to crank them down as there is no significant pressure to overcome. Teflon tape would work as well I am sure, but the grease is easier and faster.

Yes.

Also, no need to remove valve from kettle after every use...just rinse out good. I WILL take mine out after 8-10 batches and give a good soak in Oxy-clean....gunk will build up that regular rinsing won't get out.....heck, the brass one's are cheap, anyway.
