Thermostatic radiator Valve for a 2 pipe steam

How many companies carry a TRV for a two pipe steam angle? any names besides Danfoss?
Is a there a difference from an angle trv to an angle mount TRV ?
Can you use a TRV that is designated for a water system for a two pipe steam?

    This would have gotten more attention if it was posted in the steam section.
    You have a 2 pipe system which many times already has some amount of control built into it, so I am curious why you may need a TRV? Not saying you don't just suggesting before you make that kind of investment to make sure you really need them.

    As was already said pictures would really help give a more detailed answer.
