Caleffi 523178A Mixing Valve Asse1017 1 1/4 Inch Swt

The Caleffi 523178A Mixing Valve Assembly 1017 is an essential component of hydronic heating systems, specifically designed to maintain a stable and comfortable water temperature throughout your living space. By serving as a balancer, this thermostatic mixing valve controls the temperature of the water that is returned to the boiler. Cooler return water is combined with hot water from the boiler supply to operate the valve. It has a temperature sensor that measures the mixed water's temperature continually. More hot water can enter the mixture when the temperature falls below the predetermined level, which triggers the valve to automatically open. On the other hand, the valve modifies by limiting the flow of hot water if the temperature rises above the predetermined point. This continuous adjustment ensures that the blended water's temperature remains comfortable and steady.
