Can I install thermostatic radiator valves in a gravity system?

goes to 1 1/4" TRV.

However, you may not need to size the valve to the pipe diameter, but the load on the radiator.

    thermostatic radiator valves

    Can I install these in the supply lines to my radiators if I have a gravity system with an expansion tank...(open system) or do these thermostats require a closed systme with circulation pump?
    Thank you..

    Why not?

    The only problem you may have is finding a TRV larger than 1".
