Oops to quick with the keyboard.
Thanks for the quick answer. That's what I thought. I left both existing zone valves and the radiant loop has an additional flow check valve. With the Armstrong on the return side of the boiler (basically pushing through the boiler, I know it's old school but it works and it's already in place, pressure tank, scoop and air valve are on the supply side) I was pretty sure I needed it to get the water to the Taco.
