I am considering having 2 valves on each ballast tank,</div><div>top & bottom. I would just run a wire from the coil on one valve to the coil on the next</div><div>to operate them simultaneously with one through hull. It is a matter of getting the</div><div>right thickness of wire & number of turns, to get enough magnetism to pull the valve</div><div>plungers open.</div><div>Alan</div><div><br></div><div><br>Sent from my iPad</div><div><br>On 22/07/2016, at 12:03 am, hank pronk via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12px"><div><span>Alan,</span></div><div id="yui_3_16_0_ym19_1_1469102064573_4511"><span>Don't you just hate that! </span></div><div id="yui_3_16_0_ym19_1_1469102064573_4507" dir="ltr"><span id="yui_3_16_0_ym19_1_1469102064573_4506">I have to back pedal a bit about solenoid valves also. They do work fantastic, no doubt about it, but you threw a little scare into me that stuck with me. You mentioned putting a filter in to protect the seat. You have a very good point there, those valves could easily get obstructed by debris. On my last dive I noticed how much crap gets blown around them.
