In contrast to other TRVs which only act as flow limiters, the innovative design of the Danfoss RAS-B2 features a differential pressure controller that ensures all radiators throughout the home get the heat they need throughout the year regardless of whether it is spring, autumn or winter.
Additionally, pre-setting of the desired flow is done on the valve rather than on the lockshield. Something which, it is estimated, could save installers up to two hours of valuable working time.
To make life even easier the time-saving RAS-B2 valve is featured on the Danfoss Installer App which allows installers to calculate, record and document the correct flow and subsequent setting for each radiator on their smartphone or tablet.
