Can a studor valve be inside a finished wall.?

I running some plumbing for a basement bathroom, can I place a studor valve /vent completely inside a finished wall. If not should I just place a vent underneath the sink? What about the bathtub?

    Your local code will be the deciding factor here.  Ostensibly yes, you could place one inside a finished wall.  That is to say, they will fit in the space and will function there.

     I have found at least one that was tucked away inside a wall and not provided with any kind of access.  To that point, I strongly recommend you make sure there IS some kind of access.  The only reason I found that AAV was because it was stuck open and stinking up the place, forcing me to cut the wall open to get to the vent.

    An "Air Admittance Valve" has to be placed in an accessible location, so placement under the sink is the normal location.
