What's New?Caleffi introduces a new addition to the proven 5230 Series high flow thermostatic mixing valve family. These new 5230-1070 Series models are designed for "point-of-use" applications listed by NSF to meet the ASSE 1070 Standard for individual or multiple fixture applications.
Caleffi's 5230-1070 models are easy to adjust and maintain with an interchangeable thermostatic cartridge, replaceable check valves and pipe fittings. They maintain set temperature to +/- 5˚F while providing reduced valve response times with a low inertia thermostatic element. They are engineered to quickly stop the flow of mixed water if there's a failure of either the hot or cold supply. The 5230-1070 valves come standard with inlet port check valves to prevent temperature migration between hot and cold during non-use and lockable, tamper-proof temperature adjustment cap. Chemical nickel plated working parts reduce long-term wear and scaling.
The brass thermostatic mixing valves are available in 3/4 and 1-inch sizes with union-threaded and union-sweat end connections. Flow rates for mixed outlet temperature stability range from 2 GPM to 24 GPM.
Caleffi is committed to providing industry leading hydronics solutions as demonstrated by extending our family of Thermostatic Mixing Valves in North America. If you have any questions or need additional assistance, please contact Woody Dickinson or your Regional Sales Manager.
