Thermostatic Radiator Valves
Danfoss RA 2000 Thermostatic Radiator Valves (TRVs) regulate the flow of hot water or steam through free-standing radiators, baseboards or convectors in hot water and two-pipe, low-pressure steam systems. All RA 2000 TRVs conform to ASHRAE/ANSI Standard 102-1983. The operators can now be attached to the TRVs with a “snap-action” connection with an audible “click” that indicates it’s been installed correctly. Each operator consists of a saturated vapor-charge bellow and a setting dial.
