Download PDFThe RA-DV is a dynamic (pressure-independent) radiator valve designed for two-pipe heating systems. It maintains a constant flow even with fluctuating differential pressure, ensuring even heating and reducing system noise.
The DN 15 variant in a straight design has an Rp 1/2" (internal) connection at the inlet and an R 1/2" (external) connection at the outlet. The flow can be easily set in the range of 10–135 l/h using the preset 1–N. The valve is designed for a maximum working pressure of 10 bar and a maximum medium temperature of 95 °C.
