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

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.
Don't think that would work without the means to vent the hoses first. Otherwise the high pressure side would always show.
True. Still don't see the advantage of it. A lot of faff for very little (if any) monetary saving..
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.
