Description
The Siemens 257-02065B Mixing Valve Assembly is a crucial part of an HVAC system which conditions the blend of hot and cold water to provide for correct temperature. This 3 way, 1/2″ brass valve is built for long lasting and efficient performance in temperatures from 35°F to 250°F. 63Cv flow coefficient ensures betterwater flow, and the 3-8 PSI spring range provides precise pressure control the mixing valve controls the flow of hot and cold water to the correct exit temperature. They work as a set with the incoming water temperature and set point to control how much water flow internal to the boiler through the spring and valve set.
