Danfoss RLV-KDV is a dynamic double radiator connection fitting designed for valve radiators in two-pipe heating systems. The fitting is equipped with an integrated differential pressure controller with diaphragm technology, which ensures constant pressure at the radiator and valve under both full and partial load. The system is automatically hydraulically balanced to optimal pressure conditions once the flow rate has been set on the built-in valve body. The result is a lower return temperature, energy savings, and the elimination of radiator noise.
