[PSUBS-MAILIST] solenoid valves

[Alan via Personal_Submersibles]

Hank,
they will work ok, as you have the direct acting ( & you have tested them)
There are so many different models out there that I couldn't comment on 
whether one is likely to rust out or not over another. 
I just remember that my direct acting was more complicated than expected 
& had a small diaphragm & spring in them that was liable to corrosion. 
Some of my ballast fill solenoids got water in them ( should have had a check valve) 
& have rusted.
If I could find a good off the shelf option I would go for it.
Alan

This inherently provides a backup mechanism that doesn't depend on electricity if you also plumb air to that pilot line via a manual valve.
