So if you do a separate valve for each booth what about the duct? They all probably use the same exhaust duct. A separate valve for the duct?. Now you have four valves. If they are doing maintenance on one booth I bet they are all shut down for business. Just use one valve unless they are widely separated in space.

Will make it easier to maintain when you have to shut one down to clean heads or replace bags on the heads or if you have a discharge you don't have to disable all systems just the one affected. Plus if a booth or mixing area is moved it makes disconnecting and removal of the system simpler. Hopefully the budget isn't that tight to not be able to afford a few more butterfly valves.

I have two spray booths and a mixing booth side by side. Can one valve supply the three booths or are three valves required, one per booth?
