Thermostatic mixing valve

[Xavier Eastway]

Trying to find a good valve to use for radiant heating system. Have Zone 1 and 2 high temp going out to water to air heat exchangers (garage and basement) planning for 165-175 degrees. Zone 3 is radiant in floor heat (in joist, 5 loop-300') which I would expect need to temper down to 120-150 degrees. Zone pipes are 1". Supply/return line is 1-1/4" Not finding a good high temp mixing valve with good flow rates. Any recommendations?

I'm not super familiar with mixing valves but there seems to be only a little description difference between the ones that regulate temperature specifically compared to the ones that only divert. Without an actuator. Thanks

There is no standard for what "...good flow rate..." means. You'll have to be more specific.
