2 things
first there is the inverse output of reg systems, but basically you want to have 2 regs and the inline (2nd) reg should have a 150 - 300 psi gradient or difference in input and output pressures.
As far at pressure behind a valve goes, you hit the valve from one side with a hammer to open it.
The pressure on the other side is the combination of 2 things, spring pressure and air pressure.
When the air pressure reaches a certain point, it begins to make the valve open less.
