Function
Scald Protection Three-Way Thermostatic mixing valves are used in
applications where the user must be protected from the danger of
scalding caused by hot water.
The Caleffi 5213 series provides water at a safe and usable
temperature in situations where the control of the temperature
of the water discharging from a terminal fitting is of the utmost
importance, i.e. within hospitals, schools, nursing homes, etc.
The valve is designed to prevent the flow of water discharging from
the mixed water outlet in the event of the failure of hot or cold supply.
The Caleffi 5213 series is a high performance thermostatic mixing
valve and is ASSE 1070 listed.
The valve is complete with check valve at both hot and cold inlets.
