The valve is held in by 2 x allen bolts and is on the top of the exhaust manifold, once the valve is sealed shut just remove the pipe from the valve after you change the manifold, otherwise you will have a big hole in your inlet manifold and it won't hold boost too well.
As for how they work, basicly the valve lets exhaust gasses back into the inlet manifold (via the metal pipe) to soot up all the inlet side of things.

Dan, that diagram is awesome! it looks like my 4 year old son drew it ROFL
