The Caleffi MixCal 3-way mixing valve with MPN 521600A is designed for domestic hot water systems and hydronic heating systems. This valve adjusts the temperature of mixed water, ensuring it remains constant despite changes in pressure or temperature of the incoming water. The valve automatically closes the hot water port when there is a failure of either the cold or hot water supply.
This valve is essential for maintaining safe and consistent water temperatures in heating systems.
