Application:
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, precision steel and plastic pipes as well as the
composition pipe “Copipe”.
The corresponding installation instructions are to be observed.

Advantages:
Oventrop connection fitting “Multiblock T” for the connection to
all radiators with a distance of 50 mm between the pipe centres
– for regulation
– for isolation
– for draining
– for filling
– flow rate presettable
Free choice of connection to the supply or return pipe, i.e.
the valve is bi-directional (junction points in the pipework are
avoided).

Function:
Combined with a thermostat (e.g. “Uni XH”), the Oventrop
connection fittings “Multiblock T” are proportional regulators
working without auxiliary energy. They regulate the room
temperature by varying the volume flow of heating water.
The radiator is drained at the isolating and draining screw with
the help of the service tool, item no. 1090551.
