SOLD 4 - Electric Ball Valves 1" Full Port

[rocknracing]

I have 4 electric ball valves 1" NPT, 2-wire, brass, Full port with manual override and visual indictors. The manual override allows you to manually open or close the valve if you loose power to the valve. These have never been ran as I purchased more than I needed as a friend was going to need some but he sold his boat and now I am stuck with them. I am running the same valves in my boat for my ballast system. Any questions please feel free to ask.

Paid $39.80 each plus shipping and asking $32.00 each or $125.00 for all 4 with free shipping if you purchase all 4 of them.

Please help me understand the operation of these. Do they have a limit which turns off power once they are in full open or closed position? Can they be set up to fail in they open position?
