Thermostatic Radiator Valve Assemblies

RA 2000 Thermostatic Radiator Valves (TRV) regulate the flow of hot water or low pressure 1-pipe or 2-pipe steam through free standing radiators, baseboards, or convectors. When assembled with the non-electric thermostatic operators, the assembly offers an effective method of individual zoning and regulation of the ambient room temperature, which in turn reduces overheating problems within the room.
If the necessary method of control is with electric actuators, the thermostatic operators can be removed and replaced with 24VAC thermo-actuators, which are available in either ON/OFF, ON/OFF with dry contact or proportional/modulating.
