Installed a new coil from marks supply in Shenandoah and now hot water is plentiful. But too hot for safe domestic use. Now I guess I need a mixing valve. None here now. What is the best one for use. And is it fully adjustable to get water temperature to where I need it?

I can only speak for the 3/4" Taco mixing valve, which has given me 6 years of trouble free service.

The one that Larry is using is also available in 1/2", and with a gauge if you want.

I have used the Taco ones and Honeywell with good results.
Do not be surprised if that new coil gasket weeps the first time the boiler cools down, they usually need to be snugged at least once.

Best or recommended to be installed with piping in a 'heat-trap' to not allow full constant heat up against mixing valve...only allows heat at mixing valve during demand/flow.. Just turn down piping to drop 12" before going back up towards hot supply side inlet.

For domestic HW models the design max is/should default at 120*F...this is code to prevent scaulding body parts.
Others like for radiant heat are different and and are designed to go higher than the 120*F...up to 140-160*F.
