Decorator caps fit your radiator valves to allow you to close off your valve temporarily whenever you need to temporarily remove your radiator, for example if you want to remove the radiator to decorate behind it. We stock three varieties; Firstly, the decorator cap for the Bentley TRV valve. Secondly, the decorator cap for the Faringdon or Byron TRVs, and finally the decorator cap for the Admiral TRVs. In every case, the TRVs are designed so that the head can easily be removed and replaced with the cap (and replaced once the radiator is re-installed).
