Exclamation Name of this Vacuum Part??

Does anyone know what this plastic vacuum valve is called? I attached a photo of the part I'm curious about.

There are other valves similar to this under the hood.

Considering I can blow air through it in either direction, I think it has gone bad.

Looks like a check valve to me

Hey Dflamer, yeah that's what I thought it would be called too.

I've tried to find it on autohaus and autopartswarehouse but cannot seem to find it.

You think something like this might be exclusively sold from the dealer?

No I think they are pretty much available. If not a local store, I'd try something like http://www.rockauto.com/

I'll poke around some more. Definitely doesn't pop up under the typical key words:

vacuum
valve
check
air

red arrows point to EGR VACUUM SOLENOID,and blue one should work only one way.you should have more of the SOLENOIDS on the right side or drivers side.

Thanks for the all the help.

I should have done this from the get go, the part number on the side of this piece will eliminate any guess work.
