<div>Alan,</div><div>I am using 12v valves from air suspension systems. They are cheap, well free in my case and they work great. I will use them un-modified to get me through the dive season. I plan to mount them in oil filled housings over the winter, since I need them for E3000 as well.</div><div>Hank</div><div><br clear="none"></div>
