RA-DV is a series of pressure independent radiator valves, designed for use in 2-pipe heating systems together with all types of thermostatic sensors with Danfoss RA coupling.
RA-DV dynamic valves are fitted with a flow limiting device for presetting of the maximum water flow. The valves are available with maximum water flow of 25 - 135 l/h.
RA-DV has a built-in pressure regulator, which keeps the differential pressure at a constant level of 0.1 bar, thus maintaining the set flow.
RA-DV is supplied with a protective cap, which can be used for manual regulation during the construction phase.
The protective cap must not be used as manual shut off device. A special manual shut off device (code no. 013G5002) should be used.
Quality |
RA-DV Dynamic Valves™ with sensors RAW, |
|
RAE and RAS-C are certified according to |
|
the European standard EN 215. |
To be able to distinguish between other valve bodies of the Danfoss RA series the RA-DV protective cap and presetting ring are green.
RA-DV valve bodies are manufactured from brass with a nickel plating.
The gland seal pressure pin is chrominium steel and works in a lifetime lubricated O-ring. The complete gland seal assembly can be replaced without draining down the system.
Should water treatment be used it is essential that the manufacturer’s dosing instructions are strictly observed. Formulations containing mineral oil should be avoided.
In order to avoid deposition and corrosion the composition of the hot water must be in accordance with the VDI 2035.
All Danfoss radiator thermostats are manufactured in factories, assessed and certified by BSI (British Standard Institution) against ISO 9000 and ISO 14001.
