Radiant heat mixing valve adjustment

I have a 6unit apartment building with 6 zones and 6 booster pumps.... one for each unit. The 4 top units have baseboard heat and the 2 lower level units have radiant heat. These 2 lower units have the red Bell and Gossett pumps in the left of the pics. It looks like there is a mixing valve in line that comes up from the return and mixes with the hot supply line. I noticed that I had both the mixing valve and the hot supply line valve completely open all the way. Is there a recommended way to adjust these two valves for optimal heating without worrying about cracking the concrete? I was thinking with both valves open all the way I am feeding too much return water in there so I closed off the return valves slightly. Any input would be appreciated!

I can't see what it is you are talking about...

The two zones on the left... if you partially closed the valve above the pump, open it again...

Can you get sharper pictures? It's hard to see the piping below and behind the pumps...
