Valves, co systems
Four-way mixing valve
Installation instructions
Oventrop four-way mixing valve PN 10 up to
110 °C, with infinitely adjustable bypass, flat
sealing.
Model: Bronze body, regulating insert, cover and
shaft of mixing valve with double O-ring
seal made of brass.
Size: DN 25 Item no. 135 09 54
DN 32 Item no. 135 09 55
Application:
Central heating systems with circulation pump
PN 10 up to 110 °C for flow temperature control.
The supply pipe can be connected on the left or
right hand side.
Tailpipe sets are to be ordered separately.
Function:
The four-way mixing valves serve to control the
flow temperature. The setting is carried out with
the help of an electromotive actuator.
This way, a reduction of the dew point of the flue
gas in the boiler and the resulting corrosion are
avoided. For heating circuits which are operated
at high boiler and low flow temperature, e.g.
underfloor heating systems, the mixing valve is
equipped with a manually adjustable bypass.
This bypass constantly adds return water to the
supply pipe.
By using a mixing valve with a control device,
the flow temperature is automatically adapted to
the heat demand.
In combination with the manually adjustable
bypass, a vibration-free control is possible even
in systems with high boiler and low flow tempe-
rature.
Installation:
The parallel arrangement of the supply and
return allows a space-saving installation of the
mixing valve.
Connection of the mixing is carried out with the
help of G 1

or G 2 collar nuts or it is supplied
pre-assembled on the boiler connection system
”Regumat M4”.
Setting of the manual bypass:
The bypass valve can be set with the help of a
screwdriver:
Slit in vertical position: bypass closed
Slit in horizontal position: bypass completely
opened
The corresponding flow temperature can be set
by turning the slotted screw with a screwdriver.
