IIRC, 'IN' is chamber and 'EXH' is pilot. The other, barrel.

I forgot, but that just seems like the logical way to me :P

Actually, on all the Q.E.V.'s I've played with, EXH is what you hook to the barrel (it's what the cylinder exhausts to).

So, try this: hook the EXH to your barrel, the IN to your fill and pilot setup, and your OUT to your chamber.

Q.E.V.'s can be confusing, but all you have to do is just remember what they're originally used for: exhausting pneumatic cylinders.

I stand corrected, as I said I can't remember. When installing mine I just looked at how everyone else did theirs :)

BTW, how much did you pay for it, and what size? I think I know where you got it from.

yeah markfh11q is right...

no you don't need a quick burst of air to seal it...

Think logically:
The port on the side is probably the chamber (like a piston T-valve)
Then for the two inline ports: one of is tagged "in", wich will probably be the pilot/fill (duh) and then there is only one port left, wich is the.....?

Barrel yeah!
