Function
The Caleffi SinkMixer™ thermostatic mixing valve is used in under sink
and under counter applications where the user must be protected from
the danger of scalding caused by hot water. The Caleffi SinkMixer, code
521201A, 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. It is compact for easy installation and includes a cold
water outlet to the fixture eliminating the need for additional piping and
a tee for standard three-port mixing valves. It has integral check valves
on the hot and cold inlets and is certified to Low Lead Plumbing Law by
ICC-ES, ASSE 1070 listed (temperature cannot exceed 120°F).
