Keg pressure

[GRHunter]

I have a 4 port manifold and I thought that all the kegs on it would balance out to the same pressure. But I recently found out that is not entirely true. I accidentally pressured all the kegs to 30 psi. I then reset my regulator and let the pressure out of one keg thinking that it would reduce the pressure in all the kegs. All my kegs (except the one I released the pressure from) were coming out over pressurized and all foamy. So I am guessing that the gas goes into the kegs at the same pressure to balance them out. But the gas doesn't reverse itself from the kegs to lessen the pressure to balance out. Is this correct?

The poppet valve is one way, so with 30 psi pushing it closed from inside the keg, and only 10-15 psi trying to push it open, it will not release the pressure. Have to use the pressure relief valve on the keg to drop it down.

Yeah, that's kind of what I figured out. And actually, oatmeal stout with a 6 inch head isn't all bad.

Always pour two, so when you finish the first one, the second one's head has fallen to a respectable level. It's all about saving time...

Yes ... yes ... saving time, that's the ticket!

Just curious, where you at in Michigan? I grew up in Mt. Clemens, but left in ’79 when I joined the Navy.

my poppet valved allow flow in both directions. With the QD on, the poppet is held open.
If I throw an unpressurized keg in, I hear the gas equalize very rapidly.

Perhaps you have a check valve somewhere that is preventing it from flowing.

 

[JakeTheHopDog]

Interesting. I just tried it on mine and it didn't equalize either. Checking further on it, I found the specs on my 2 way manifold I use to carb a new keg, and it has a check valve. GRHunter, check the specs on your manifold.

I am about 7 miles north of Detroit.

If any specs came with my manifold I probably tossed them out. And as far as I am concerned it doesn't matter where the issue is, or why my gas doesn't equalize downwards. The fact that it doesn't equalize downwards is all I need to try and remember. To paraphrase Sherlock Holmes, I don't want to clutter my little brain with any unnecessary information.

"You see," he explained, "I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you choose. A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things so that he has a difficulty in laying his hands upon it. Now the skilful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones." - Sherlock Holmes, in "A Study in Scarlet"

Sounds like check valves in the manifold. That is a good thing to keep any back flow at bay.

Just drink a gallon or 2 out of the over pressurized kegs . Do it for the children :fro: .
