mixing valve

Im sorry I ment to type four loops of 3/8 onix 50 feet each not 25. Im suprised no one has answered my question yet. I just need to know if that size valve would be ok, the 3/4 valve`s cv rating is not much more it seems like the one inch valve may be oversized. Im using a Grundfos ups15-58fc circ 3/4 supply and return up to the mixing valve.A4T254

Loop length

Each loop could be 150 ft, no problem. You could do this with a 1/2" zone valve. The 15-58 is OK at low speed, the Alpha pump would be better, as it can pump at much lower speeds.
