You can mount them wherever you want,

Closer to bags = Faster response lifting/dropping (sometimes more noticeable than others)

On or Closer to tank = Sometimes a little easier, sometimes less fittings, can slow down the system. Usually not by much, but if you're going for speed.. closer to bags is more practical.

I put most of my customers valves by the tank, that way there is less chance of something messing up the line and loosing yer air pressure.
