Download PDFThe RA-DV is a dynamic (pressure-independent) radiator valve for two-pipe systems. It maintains a constant flow even with fluctuations in differential pressure, which stabilises operation and reduces noise.
The DN 20 variant in a straight design has an Rp 3/4" (internal) connection at the inlet and an R 3/4" (external) connection at the outlet. The presetting 1–N covers a flow rate of 10–135 l/h.
