When I said you know how this works I was referring to the forum and your lack of vehicle information but now that you have expanded, no, you do not understand how this works and no, they do not all work the same.
If this is all still hooked up properly it will work the way it was designed. The valve is open because it is supplying a bypass for the vacuum back to the manifold and when it closes, it basically forces vacuum to the EGR valve.
All this is assuming that this is Federal/Canadian emissions and not California.
