risers pipe banging noise

Hi all,
I have recently moved into an 100-year-old NYC building (9th floor out of 10). I have a one-pipe radiator in my bedroom. The radiator is connected to a riser pipe (inside the wall). Whenever the pipe warms up, the pipe makes a loud banging sound/water hammer that is guaranteed to awake me every single night during the past month. Even if I shut down my radiator, the noise still exists.
I have talked to the building manager, and they have (a) changed my air valve and (b) hired a pipe engineer to examine the boiler, condensate, valve, other units in my building etc. In the end I was told that "everything looks fine" after their one-month-long investigation.
The building manager said if the situation persisted (it is), they would open the walls, but I have no idea what they could do there. Is there anything else I could ask the manager to consider?

that rad valve should be all the way open,
or possibly, all the way closed, but closed could still leak by, and cause hammering,
and then,
if the valve IS all the way open, its disc could have disconnected and also be causing hammering,
see if they'll open the valve and check,
Or, it's in the wallknown to beat dead horses0 -
and this applies to the rad above you, and all those below,

The usual first thing is to raise the entire radiator, both ends....with the vent end higher than the valve end.
But the supply looks like it comes out of the wall with a 45 degree elbow that looks pretty fixed in place.
There might be a riser pipe in the wall box where the pipe comes out.
It may come from the basement.
I would check the valve first.
That should be a gate valve, not a globe valve.
Could we get a better picture of the valve? Straight on shot.0
