Function:
Combined with a thermostat (e.g. “Uni XH”), the Oventrop
connection fittings “Multiblock TF” are proportional regulators
working without auxiliary energy. They regulate the room temperature by varying the volume flow of heating water.

Free choice of connection to the supply or return pipe, i.e.
the valve is bidirectional (junction points in the pipework are
avoided).
Application:
One/two pipe central heating systems, max. operating pressure
10 bar (PN 10), operating temperature 2 °C up to 120 °C (for
short periods up to 130 °C) irrespective of the type of heat
source.
When choosing the operating fluid, the latest technical status
has to be considered (e.g. VDI 2035 – Avoidance of damage to
hot water heating systems).
To guarantee a silent operation, the differential pressure across
the fitting should not exceed 200 mbar in any operating status.
For use on radiators with supply and return pipe connection.
Installation can be carried out with any standard pipe material.
Oventrop offers suitable compression fittings for copper,
stainless steel and plastic pipes as well as the composition pipe
“Copipe”.
The corresponding installation instructions are to be observed.
