Thermostatic radiator valve bodies (TRV bodies) are fitted on the supply or return of radiators or heat exchangers. Together with a radiator thermostat, for example the Thera- 4, they control the room temperature by regulating the flow of hot water into the radiator or heat exchanger. The temperature of different rooms is controlled individually and energy is saved. TRV bodies of this type have quiet operation and are fitted to the supply of radiators on two-pipe systems with medium flow rates. The valve insert can be replaced while the system is running and without draining using the service tool (see Accessories).
