We are in the process of building our glycol system at the moment and I have a question about placement of the solenoid valves on the supply header. Is it necessary to place them on both the cooling side and return side? Or is the cooling side enough?
At the moment I am thinking of placing them on both supply and return lines, to prevent back flow into a jacket. Or is that not an issue? Obviously placing them solely on the supply line would be cheaper and hence my question.
Any help would be appreciated.
