The Caleffi MixCal™ three-way thermostatic mixing valve is used in systems producing domestic hot water or in hydronic and radiant heating systems. It maintains the desired output temperature of the mixed water supplied to the user at a constant set value compensating for both temperature and pressure fluctuations of the incoming hot and cold water. The MixCal™ is fail cold: for any failure of cold or hot inlets or valve function, the hot water port closes.
