RA 15/6TB valve for two-pipe systems

Application

Applications

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 one- and two-pipe
systems with pumped circulation and has xed
kv-values.

In one-pipe systems, the system water ows
partly through the radiator and partly through
the built-in bypass into the valve.

Ecient mounting is enabled by a range of com­pression ttings 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 bae plate
or special connector, may be required.
Please note, when a bypass valve is tted, not all
radiators will provide the performance quoted
in their catalogue, and variations in performance
may occur, where dierent radiators are combined.
In these cases, please ask your radiator manufac­turer for detailed information.

RA 15/6T valve bodies can be tted with RA 2000
thermostatic sensors and TWA thermal actuators.
