Radiator Dynamic Thermostatic Valve RA-DV 1/2″ Straight (click) Danfoss

RA-DV is a dynamic (pressure-independent) radiator valve designed for two-pipe systems. It maintains a constant flow rate even when the pressure difference fluctuates, ensuring even heating and reducing system noise.

The straight DN 15 variant has an Rp 1/2″ (internal) connection at the inlet and an R 1/2″ (external) connection at the outlet. The flow rate can be easily set in the range of 10–135 l/h using presetting 1–N. The valve is designed for a maximum operating pressure of 10 bar and a maximum medium temperature of 95 °C.

Main features:

• Pressure-independent flow regulation for stable operation
• Flow presetting 1–N for quick system balancing
• Differential pressure operating range 0.1–0.6 bar
• Durable construction for maximum pressure of 10 bar and test pressure of 16 bar
• For two-pipe systems, straight design, DN 15, 1/2″ connection
