DRV80RBSDS Digital Recirculation Valve (DRV), with BrainScan® - hot water monitoring control module, designed specifically to be the primary water temperature controller in a continuously pumped circulating hot water system. DRV80R is supplied with a recirculation return manifold as shown.
Digital technology provides enhanced water temperature control accuracy which resists zero system demand "Temperature Creep" without the use of a manual throttling valve or a temperature activated pump shut-off device (aquastat).
