Ron, We have a few options for mixing valves. If this a residential home the 521 MixCal or 520 AngleMix could be good solutions. Sizing the mixing valve is important because every mixing valve has both minimum and maximum flow rates. Piping is also important, especially if you have a domestic hot water recirc. line in the home. The piping diagrams are in all of the installation instructions. I would recommend contacting Caleffi Tech Support at 414-238-2360 for help in selecting the correct option. We can provide the piping and installation instructions for you.
