Dynamic Valves RA-DV
Dynamic Valve 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 10 - 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 valve bodies are manufactured from brass with a nickel plating. The gland seal pressure pin is chromium steel and works in a lifetime lubricated O-ring. The complete gland seal assembly can be replaced without draining down the system.
Danfoss Dynamic Valve™: a simple solution to a daily challenge
Danfoss Dynamic Valve™ is an innovative radiator valve with a 2-in-1 valve design. It combines a thermostatic radiator valve and a differential pressure controller for accurate temperature control and automatic hydronic balancing in a single product.
The built-in differential pressure controller eliminates pressure fluctuations in a two-pipe heating system. By using Dynamic Valve™ a perfectly controlled and automatic hydronic balanced heating system is simply established.
For designers
Dynamic Valve™ is good news for everybody involved in designing or specifying of two-pipe heating systems. It has all the advantages of automatic hydronic balancing combined with optimal temperature control.
For installers
By installing the valves you also install automatic balancing at the same time. To commission the system correctly the valves just have to be set to correct maximum flow at each radiator.
For building owners
Dynamic Valve™ is a product typical to use in residential buildings. Many owners, occupants and other users will recognize typical heating problems like noise, uneven heating and high energy bills. The indoor comfort will be greatly increased when Dynamic Valve™ is used.
