Honeywell VT117-15S Thermostatic Radiator Valve 15mm Straight
The Honeywell VT117-15S Thermostatic Radiator Valve (TRV) provide local control of room temperatures to maintain comfort and save energy.The Honeywell VT117-15S senses the air temperature around it and controls the flow of water through the radiator to which it is fitted, to maintain and limit the temperature within the room.

Air from the room passes over the sensor of the TRV causing the liquid to expand as the temperature rises. The sensor acts onto the valve spindle causing the TRV insert to close. When the temperature falls, the liquid contracts and the spring-loaded valve spindle opens. Only the amount of water required to maintain the room temperature set on the radiator thermostat will flow into the radiator.
