RA 15/6T valve for one-pipe systems RA 15/6TB valve for two-pipe systems
The RA 15/6T and TB are special lance (bypass) valves, which allows the radiator to be connected at one point only - underneath or at the side of the radiator, as required.
It is designed for conventional oneand two-pipe systems with pumped circulation and has fixed kv-values.
In one-pipe systems, the system water flows partly through the radiator and partly through the built-in bypass into the valve.
Efficient mounting is enabled by a range of compression fittings for steel, copper, PEX and AluPEX pipes.
To prevent scale and corrosion, the system water should comply with VDI (Verein Deutscher Ingenieure) guideline 2035.
Depending on the type of radiator, a baffle plate or special connector, may be required.
Please note, when a bypass valve is fitted, not all radiators will provide the performance quoted in their catalogue, and variations in performance
may occur, where different radiators are combined. In these cases, please ask your radiator manufacturer for detailed information.
RA 15/6T valve bodies can be fitted with RA 2000 thermostatic sensors and TWA thermal actuators.
