I am trying to find some 1/2" solenoid valves that don't cost me an arm & a leg. I bought 5 on eBay a while back that sounded perfect, 1/2" full-port hot water/steam, slow-closing, 120VAC coil made by ASCO.
I plumbed one in and played with it, only to figure out after the fact that it is a piloted valve. It operates off of the pressure differential and requires 5 PSI minimum to reliably close. Obviously, this is not practical/possible with the March pumps I am using.
What I want is 1/2" valves, and either 120VAC or 24VDC coils. They will have to be direct-acting type of valves so that pressure is not required to open or close them. And also be able to withstand 200°F+ water.
Anyone have any ideas what is out there?
