The precision, sensitivity and long service life of the
mixing valve will be ensured only insofar as it is properly maintained and if
it is correctly chosen beforehand.
In order to define the size of the mixing valve which is best adapted to a given
installation, it is absolutely necessary to know two elements : the total instantaneous
flow rate, and the dynamic pressure available to the flow for the hot and cold
water, at the mixing valve's inlets.
It can be measured or calculated, by using the DARIES Chart or the WATTS software
package, which is designed to validate the calculation carried out manually in
order to choose the right mixing valve (according to pressures, pipe diameters,
desired flow rate and number of points of use).
In no case should you permit static pressure greater than 10 bars.
• The proper dimensioning of the mixing valve,
that is, the choice of flow rate (according to the data in our technical leaflets).
• The hot water temperature which must not
exceed 85°C in order to avoid premature aging of the equipment and the installation,
but must remain higher than the set point with a difference of 5°C between
the two fluids.
• The meter for the main water supply, whose
given maximum flow rate determines the installation’s possible
flow rate.
• The length and diameter of the piping which,
through pressure losses and water speed, will facilitate or complicate the installation’s
operation.
• For this reason, the diameter of the inlet pipes (Hot and Cold) and the outlet pipe diameter for mixed water departure, must be the same nominal diameter (DN) as the mixing valve, a difference of one diameter DN (in more or less) is only tolerated.
Connections :
All our mixers for Group Installations (T9107, T9715,
ULTRAMIX and Flanged models) are designed to take in HOT water on the LEFT-hand
side and COLD water on the RIGHT-hand side.
On special request, when this arrangement is impossible, mixers can be fitted
out in the opposite manner with a specific cartridge type “IN”.
