Safety
The Caleffi 5213TM series thermostatic mixing valve can give stable operation provided it is
installed, commissioned and maintained as per the recommendation outlined in this manual.
This valve cannot be considered as an alternative to adequate duty of care during its use and
operation.
General
The Caleffi 5213TM series is a high performance
thermostatic mixing valve and has been specifically
designed
and
requirements of "AS 4032.1 Thermostatic Mixing
Valves-Materials, Design and Performance
requirements".
In certain sections of our society, there is a need to
protect the most vulnerable from the danger of
scalding caused by hot water. Hence, the need for
thermostatic mixing valves.
The Caleffi 5213TMTM series provides water at a
safe and usable temperature in situation 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 valve is complete with strainer and check valve
at both hot and cold inlets.
with strainers and check valves at the inlets 15 mm (1/2")
male,compression end connection for copper pipe.
with strainers and check valves at the inlets 20 mm (3/4")
male,compression end connection for copper pipe.

  • Page 3 In the event of a failure of a the hot or cold supply, the piston will shut off, stopping water discharging from the mixed water outlet. The Caleffi valve requires a minimum temperature differential from hot inlet to mixed water outlet of 10°C to ensure the correct operation of the thermal shut off feature.
  • Page 4 20 mm Kv= 1,7 (m 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.
