I found thanks to a nice fellow at Hy Power in Western Canada have these Canadian Spunding Valve Parts

V07-200-NNKA Norgren - ¼” n.p.t. ports, adjustable from 5 to 100 psi

18-013-203 pressure gauge for above relief

Hope this helps someone to find parts.

This is great! I have a spare sanke available that I'm getting ready to use for this. One question for sanke users, are you using the original spiral snap ring or a replacement from mcmastercarr?

I have the keg & dip tube, but can't find the ring. It looks like there are a few possibilities for replacement, but I'm not sure about the reliability of a different kind of snap ring vs. the original.

Thanks.

Bulldog - Some guys have had problems with the snap ring. Unless your diptube o-ring is in perfect shape, the snap ring isn't thick enough to compress everything together as well as it should. The original spiral rings are available from McMaster (http://www.mcmaster.com/#92370a251/)

It would be beneficial if we could get a wiki entry for the serving/filtration portion of the pressure fermentation process. I'm sure a lot of guys (myself included) are wondering how they get their beer that's finished and carbonated, transferred from the fermentation vessel to the serving keg without transferring half a yeast cake.

Perfect, thanks! I found a link to them on grainger as well, but would prefer mcmaster.

I recently tried the closed-system pressurized fermentation technique outlined in this thread. I didn't have a Sanke keg big enough to ferment my 5.5gal batch, so I instead split the batch between two cornies and tee'd the spunding valve to both.

My problem comes in that there is a yeast cake on the bottom of one of the corny fermenters that is plugging my dip tube and/or poppet valve. I had intended to counter-pressure transfer the beer through a filter to the serving keg, but with the dip tube clogged, there's no way to empty that fermenter under pressure.

So... I've decided that I need to rack the beer to the serving keg. The problem is that the beer is carbonated with ~2vol of CO2. Attempts at using my autosiphon fail because the beer offgasses enough to break the siphon during transfer.

Any tips/tricks to making this work? Would using larger tubing and no autosiphon be less likely to break siphon? How can I keep the CO2 from coming out of solution, or do I have to decarb completely?

Is the diptube clogged or the poppet? If its the poppet, you can depressurize, remove keg poppet as well as the poppet in your liquid QD, and then recharge with C02 and transfer that way. Just make sure you depressurize again before you pop the QD off or youll get a krausen shower.

I find that you almost have to keep all hops out of the fermenter or else you will get clogged diptubes. Usually trub and yeast will get passed the poppets and be pulled through in the first cup or so of transfer.

If its the diptube, I would suggest depressurizing, unclog and either try again or cut the diptube to be above the trub.

In all honesty, I'm not sure. One of the kegs dispenses fine, albeit with a bunch of yeast coming over. The other dispensed about 4oz, then just stopped.

I measured, but want to verify that the rings are 2 1/4", is that right?
