TA-MIX
Thermostatic mixing valve for control of domestic hot water supply or
of similar smaller systems.
Key features
>
Temperature range
The valve can be set between 35°C
and 65°C.
Technical description
Applications:
Domestic hot water systems.
Functions:
Control of domestic hot water supply or
of similar smaller systems.
Pressure class:
PN 10
Temperature:
Max working temperature: 100°C
Temperature range:
35 - 65°C

Installation
Before fitting the valves, flush the lines
thoroughly to remove any dirt that could
affect performance.
A heat block or check valve should be
fitted in order to prevent convection.

Hot water outlets upstream of TA-MIX
Any outlet upstream of the TA-MIX valve,
e.g. for dishwasher or similar, causes
temperature variations in the draw-off
warm water when run at the same time.
The reason for this is that the pressure
drop through the water heater increases

sharply when hot water is drawn off,
whereas the pressure drop on the cold
water side up to the mixing valve remains
the same.
If a hot water outlet is arranged upstream
of the valve a non-return valve must be
fitted upstream of the mixing valve.
