How to move an air valve on a Sunrad radiator?

I have three Sunrad radiators with the air valve located in the wrong spot. I have a one pipe steam system, and the valves are in the upper corners. On one radiator it’s even on the wrong side (same side as the supply).


In the correct location for the valve there is a raised circle. Is this a plug that can be removed or is it just a guide for drilling and tapping a hole?

Thanks!

    Yes, the correct location is halfway up on the opposite of the supply end.

    If that is a removeable plug it would have an inside hex for an Allen wrench. If not, it could be drilled and tapped.

    UPDATE: what appears to possibly be a plug IS a plug. I used a number 5 hex wrench. Scraped the paint, sprayed some penetrating oil, used some elbow grease, and voila!

    yeah, but, wait,

    is that the right end, or the left end, from the first picture?

    the 1st picture looks like the supply comes in the right side,

    you would want the vent on the left side, 1/2 way down,

    good catch. It’s actually a different radiator than the first picture. Supply is in the opposite side.

    (The before picture is old. I had to swap out the air valve bc it was old and failing this past winter.)
