Neptune SV-1 Solenoid Valve Question

[ubiq]

I have a gravity fed kalk stirrer that I want to automate, so that when pH drops below a certain level, my RO/DI top-off feeds to the stirrer rather than straight to the sump. This would require that one solenoid valve be in the open position most of the time. Is the Neptune SV-1 suitable for this purpose? I've read that they get hot when energized.

Neptune is NC as you note. I’d not personally be comfortable running one in an energized state constantly, but I do not know what the mean time to failure would be under that condition. Why don’t you get a NO solenoid? I think autotopoff.com sells them.

why not run another pump from your ato container instead of same pump that does top off ?
