I have to design my system with a Y connection right off the DC. I'm wonder if I should install a blast gate on each side - left and right in effect cutting off one of the runs when not needed. This main line blast gate would be in addition to each tool's blast gate.
Is there any value in having a main line blast gate? Would the system be more effective without having to pull air all the way from the tool's closed blast gates? Yes no?
Is this making sense?

when I had my DC setup with a Y right off the DC I put a gate on each Y.

Seems to me in an ideal world, there would be no need to do so. Once the vacuum was created in a sealed system, it shouldn't make any difference. On the other hand, in the real world, there is no such thing as a truly sealed system so maybe there is some advantage. On a practical level, speaking as a guy who just installed a central DC, I am all the time forgetting to open or close the blast gate when moving between machines, so having one more gate in line would prove a real annoyance.

I've got an 8" Y right at the cyclone, works just fine. Besides, I'm not going into the attic to play musical dust gates.

That is exactly why I did this to my system. Green light indicates that a gate is open.
Momentary switch on each gate.

No real reason to do so unless you have some serious leakage in the trunk lines. If these are 4" lines it probably doesn't matter at all.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.
