Co2 transfer loop

[Larse]

This seems a bit more complex than the one I had envisaged? The spunding valve is fully open, but the pressure into the destination keg is reduced by the inline regulator which shows the pressure on the output side. The open spunding valve's manometer shows the pressure on the input side.

Why two regs? Imo I can only think that makes it a pita to operate.

Or have I missed the point.. Lunch and a think is called for...

Well you don't actually need the spunding valve reg. You could use the manometer in your scenario instead.

I agree setting a pressure (spunding valve) is a good idea but a spund is operating the wrong way round.

I want for bring up the lower pressure UP in the dispense keg, not maintain what's in the co2

It might be a bit confusing. I only have the spunding valve in there for pressure measurement on the CO2 side (source). The T-piece and gauge setup would work just as well. The white unit is a regulator, so you can reduce the pressure in the destination keg. The gauge on that unit (white) gives you the pressure in the destination keg.

 

[MashBag]

I thought you might say that.
Is the destination gauge accurate enough?

Currently thinking of rewiring a pair of these. Do you know what the thread is?

 

[Larse]

If you want accuracy...

I really wish kegland stuff could just make stuff that's isn't vomitously hideous.

Can you tell

It's actually dawned on me the easiest way is 1 gauge and valve either side.

Why do you need a valve either side? I had that in the original setup I proposed and you queried the valve on the spundy. Which in retrospect I agreed with.

 

[MashBag]

You can check both sides pressure with just one gauge by closing them in the right order.

I thought they were regs?

Don't think that would work without the means to vent the hoses first. Otherwise the high pressure side would always show.

 

[MashBag]

Nope. They will equalise when opened to either side.

True. Still don't see the advantage of it. A lot of faff for very little (if any) monetary saving..

 

[MashBag]

Not a huge ammount of faff that I can see... And on the plus side, no co2 cost, stress or hassle.

Winner, winner in my book.

I'm talking about the one gauge loop. To set the pressure on the demand side, you have to do a fair bit of trial and error. You're setting the inline regulator blind, opening the supply side valve and then closing it again so that you can read the gauge. Rinse and repeat until you reach your desired demand side pressure.

Couldn't be arsed with all that. Just have a gauge on each side and you can fire and forget.

Yes indeed. But it's still trial and error with two. The only difference is the choice of valve.
