    Solenoid Closed/Open

    Neptune SV-1 Solenoids are normally in the closed position. Can I send power to open the Solenoid and keep it open for hours at a time? Is this improper use of the solenoid and will this shorten the life of the Solenoid?

    Thank you for your input. How do you use these solenoids in your system?

    I use it as a fail safe on my ATO. Its not designed for saltwater per a ticket I opened for Neptune support asking that question. They recommend only use for air or freshwater.

    I have a similar set-up, my solenoid is only OFF about 4 hours per day. I do notice that it gets very warm. Is there any thought to making a normally open solenoid? Is there a hack so that default state could be made open?

    You would need a different solenoid.

    You might be an engineer if...You have no life and can prove it mathematically.
