Right, about the only time you would connect the gas to the keg would be if you, as I suggested, pressurized the keg manually to calibrate the spundig.

Quick update:

I did a trial run on a 20 BBL fermenter today. For the most part it went pretty darn well! I am going to try a couple of ball, spring, distance combos out though to see what the most predictable setup is. The one thing I noticed today is the viton ball I used tends to want to get stuck in the reducing coupling taper and it takes a certain level of pressure to force it out.

Only other note which I think I mentioned before is this setup really needs a spring that is ground flat. I will be on the hunt.

I'm headed back tomorrow for more trialing.

What is the source and part number for the clear pipe? I'm thinking sight glass for my O2 stone/thermometer assy.

Go to pipe nipples, threaded on both ends.

Today's update: slightly larger ball is better. I drilled another cap to see if the spring will compress a bit straighter without grinding the ends. The valve is going into full testing on the 20BBL fermenter for spunding @ 17 psi. Should know soon how good the spring I chose is.

I see a still pic, but no vid. Still, it looks damn cool. You're rocking that thing, my man! You get it dialed in just as you want it and you could have a tidy little side business on your hands!

Did you every finalize the design? If so, do you have a final parts list available?

Looks like a great design.

Thanks
