RLV-KDV
RLV-KDV is a Dynamic H-piece designed for radiators with integrated valves (valve radiators) in 2-pipe systems.
Self sealing connection pieces ensure that RLV-KDV can be used both for radiators with an internal thread of G ½ and with an external thread of G ¾ A. A fill and drain tap is available as an accessory. Connection to copper, soft steel, PEX and Alupex pipes is made with Danfoss compression fittings. See separate datasheet.
In order to avoid deposition and corrosion, the composition of the hot water should be in accordance with the VDI 2035 guideline (Verein Deutscher Ingenieure).
Features and benefits
- Integrated differential pressure controller using membrane technology
- Constant pressure over the radiator and valve in full and partial load
- Self-balancing to optimal pressure conditions once the flow presetting on the integrated radiator-valve is done
- Lockshield on supply and return
- Self sealing connection pieces to the radiator for G ½ internal thread and G ¾ external thread
- Filling and draining possibility (with fill and drain tap 003L0152)
