I wondered if somebody in the community might be able to help me with a little problem.
I need to source a powerful 12v DC solenoid valve which is as small as possible, say 50mm square, with 1/8 ports or smaller but most importantly it must be normally closed and able to work under pressure in both directions. I have found perfect valves capable of 10 bar but all of them can only flow in one direction. I hope there is such an item.
BTW. I would be happier if 6-12v DC but I think that might be asking far too much.😊
