The valve goes between the regulator and the tank. As I understand it,
regulator can be had with two functions. One supplies constant pressure
and the other supplies a constant rate of flow. If you use a constant
pressure regulator, the pressure won't build up on the down-line side
beyond whatever the devices pressure output level is.

I'd like to know this as well.
