The thermostatic radiator valve (TRV) is one of the longest lasting pieces of heating equipment in your home. With their simple, steam-powered design of a normally open spring loaded valve, bellows (coated in thin plastic) and mounted operator, these units have been around since the 1920's and hardly ever break.
