Construction details
Anti-scale materials The material used in the construction of the Calef
AngleMix 520 series thermostatic mixing valve reduces jamming caused
by lime deposits. All the working parts such as shutter, seats and slide
guides are made of a special anti-scale polymer material, with a low friction
coefcient, assuring long term performance.
Temperature setting and locking The control knob permits temperature
setting between minimum and maximum in one turn (360°). It also has a
tamper-proof system to lock the temperature at the set value.
Thermal shut-off In the event of accidental cold water supply failure,
the shutter seals off the hot water passage, thus preventing the delivery
of mixed temperature water. This is only guaranteed when there is a
minimum temperature difference between the inlet hot water and the mixed
temperature water delivery of 18° F. Additionally, the tight closing hot inlet
port prevents temperature creep in recirculation applications.
As a convenience, the codes with "AC" sufx are supplied complete with a
check valve in the hot and cold inlet ports.
