Does anyone who knows electrical systems a little better that me have an idea whether this will work for a glycol control system?
I plan to wrap my fermenters with a copper coil and insulation. I would like to run a glycol loop and have motor actuated ball valves open to allow the flow of glycol through the coil when the temperature controller calls for cooling. Basically, the valve is normally closed and the glycol runs in a loop. When the fermenter temperature reaches a high temp setpoint, the valve opens and allows glycol to cool the fermenter. When it reaches the setpoint temperature, the valve closes.
I am thinking that 12v is better than 120v for this because it would be nice to have low voltage wire to the valve wrapped with the temperature probe going to fermenter from a wall mounted control panel. It seems like a typical temperature controller like this:

will work with these motorized ball valves:

Anyone see any fatal flaws or have ideas for this? Is there a reason not to use 12v equipment?
