Hi all,

Looking for a solenoid valve that is normally open, and closed when energized. However, would also like it to close in the event of a power failure. Does such a device exist?

OR

Do I connect two valves in series

One solenoid valve that is normally open, and closed when energized, which is what I would like to control. A second normally closed, open when energized, connected to the power outlet in series.

Does that make sense?
