Flow rate
The Caleffi 5213TM series is a thermostatic mixing valve suitable for a point of use application
or for a limited number of outlets (maximum 3).
For this reason the flow rate that is passing through the valve is the same as that of the final
outlet, e.g. mixer or tap for washbasin, shower, bath or bidet.
The system must be sized taking into account the current legislation with regard to the nominal
flow rate of each outlet. The reference is AS/NZS 3500.1.
