2 pipe steam with dan fauce valves
The side of the house that the plumber put the dan fauce valves in will not pass steam. The dan fauce valves are a foot from the radiator. Are they in the proper spot? Original valves were manual and there were no issues then.

What size and type are the valves, and why are they there? Valves on steam lines must be full port types, and certainly not globes, unless they are right at the radiator.

2-pipe system can support tiny orifice. But I'm curious as to whether they are TRV or something else.

provided it's at, or very near, the radiator. In a main or riser a reduced port valve can cause a problem (a lot of condensation just beyond it, when the steam tries to expand again).

Did the installer do something silly like order a version of the valve that puts the thermostatic element in one of the wrong positions pointed out in the attached piece of Danfoss literature?
