I have a one-pipe steam system. I have been replacing the valves with Honeywell valves and Thermostatic radiator valves to better regulate the heat. Does anyone know what TRV is compatible with this valve? Honeywell discontinued Thera-4 Universal Thermostat Radiator Actuator w/ Internal Sensor & Danfoss RA Connection Adapter and I can't figure out what replacement works with the Honeywell V2043HSL10. I tried Supply House and they have sent me incompatible TRVs….twice. Thanks.

    Are these inlet valves or vents? I hope you are not trying to use the inlet valves for control. They aren't meant for that. Use the vents.
