Thermostatic Radiator Valves
A thermostatic radiator valve automatically throttles water to the radiator when room temperature reaches the set value, thanks to the temperature-sensitive element in its head.
It is used for room-by-room temperature control and energy saving in homes, offices, schools and hotels. The product range includes 1/2″ straight and angle pre-settable bodies, thermostatic heads, PEX types and a smart digital head.
Main Applications
- Residential radiators
- Offices and meeting rooms
- Schools and dormitories
