Construction details
Anti-scale materials The material used in the construction of the Calef
MixCal 521 series thermostatic mixing valve reduces jamming caused
by lime scale deposits. All the working parts such as shutter, seats and
slide guides are made of a special anti-scale 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.
