Product Description

Thermostatic radiator valve bodies (TRV bodies) are fitted on the supply or return of radiators or heat exchangers.

Together with a radiator thermostat, 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. Thermostatic radiator valves of this type have quiet operation and are fitted to radiators on two-pipe systems with large flow rates or radiators in one-pipe systems. The valve insert can be replaced while the system is running and without draining using the service tool. TRV bodies of this type are suitable for Honeywell Home radiator thermostats with M30 x 1.5 Connection, certain Honeywell Home MT4 actuators or Honeywell Home Hometronic HR80 and Roomtronic HR40 actuators.
