This steam TRV?

has anyone use this valve? It seems like a simple way to add control to single pipe steam rads. Clicked on the Oventrop banner ad along side.

Works perfectly with a 2 stage firing set up

What makes them any different than any thermostatic radiator vent?

Danfoss has had a similar model for years.

I wonder if you have to buy a separate vacuum breaker, like the Honeywell ones?
