Thermostatic radiator valve
A thermostatic radiator valve is fitted on radiators and convectors to regulate room temperature. The valve functions automatically and is comprised of two parts: a sensing element and a valve casing.
There are two basic categories of pipe systems: one-pipe and two-pipe sytems. The type of system installed will have an influence on dimensioning radiators and piping. A general characteristic of a two-pipe system is that the radiators are dimensioned for the same flow temperature and the same temperature difference.
