Caleffi 521516A 3Wmixing Valve 3/4 Inch Pressure Probe

The Caleffi 521516A is a 3/4-inch three-way mixing valve equipped with a pressure probe, tailored for integration into hydronic heating systems like boilers and radiant heating setups. By combining hot and cold water streams to get the optimal setpoint, this valve is essential in controlling the temperature of water running throughout the system. Its functionality depends on the pressure probe, which continuously checks the system's water pressure and modifies the valve to keep the temperature constant. The Caleffi 521516A ensures maximum comfort and efficacy while averting potential problems like scalding or inadequate heating by carefully regulating water temperature. This mixing valve has several advantages, such as higher HVAC equipment longevity, better system outcomes, and increased energy efficiency.
