[PSUBS-MAILIST] 12v solenoid vent valves in sea water

[hank pronk via Personal_Submersibles]

Brian. I have two of these valves on E3000. One is open to the environment and the other is inside a rubber oil filled housing.  I used the brass ones on Gamma because it is in fresh water.  I have thousands of dives on these valves on an ROV in fresh water. I would either enclose them in oil or just try it and see what happens. Maybe put one in a bucket of sea water for a month and actuate it daily.
