Domestic hot water mixing valve

I just purchased an 1 family house and i need to install a mixing valve to control the domestic hot water temperature. I have a combo boiler with a tankless water heater and i am looking for suggestions as to which brand is liable to install.

    I'm fond of the Caleffi 521A with union fittings and outlet temperature gauge.
