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
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 tee for standard three-port mixing valves. For single-pipe fixtures
(tempered water only), code 521201AP includes a plug for the valve
cold outlet port. 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).
