Which water valve? Gravity fed - no pressure

Hello!

I'm well on my way into building out my system, but I've noticed the 12v valve I have requires a 'minimum' pressure to operate. Looking around on the web, most of them do have an operating 'mpa' - which I don't know the math on... what I do know is my system will be gravity fed.

Does anyone else here run a system with water that is not pressurized? If so, which valve/solenoid are you using?

My next option is to power an air lift, but I'd rather find a valve I can use for now..

Thanks!

Hi There,

Just made a video testing the motorized valve. You can check it here:ù

@hydrosys4 Ok, I think I get it. I have the same 3 wire DC Valve. From my limited understanding there shouldn't be any harm in burning out the motor/valve if each relay is accidentally closed? I am looking into using a software and/or hardware "interlock". There's a higher risk of the software interlock potentially not working and have been trying research a hardware interlock using relays.
