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. <div>Hank<br><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Mar 7, 2020, at 7:59 PM, Brian Hughes via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr">

After Ian's reply thought I'd start a separate thread.</div>

Hank pioneered using inexpensive 12v solenoid MBT vent valves. I'm set to go with 1" brass valves for Harold's side mounted tank swap. Could upgrade to stainless if needed, but Hank used brass ones for Gamma so starting there.</div>

Wondering if anyone else has played with these yet. Haven't completely pulled one apart so don't know what might be an impact of long term use in sea water. Maybe disassemble and coat with silicon grease on a regular basis? </div>
