Drayton TRV4 Classic Thermostatic Radiator Valve 15mm Angled with Lockshield

The TRV4 Classic has achieved the highest Class I rating for energy efficiency under the certification scheme of the European valve manufacturers association (TELL).



The rating is based on how quickly a TRV reacts to changes in room temperature; how effectively it maintains stable room temperature; and how it performs after changes in water temperature and system pressure.

Britain’s best loved TRV4 range of thermostatic radiator valves, Drayton's TRVs set the standards for design, performance and quality. The range includes Lockshield and Pushfit packs to suit most domestic and commercial heating systems.
