I have been looking around trying to source some solenoid valves for my system that didn't cost me an arm & a leg. Someone sent me a link to an eBay store that seemed to offer just that. You can find it here: eBay Store - valves4projects: Brass Bodied Valves, Plastic Bodied Valves, Valves with Hose Barbs.
I ordered a couple to check them out to see if they were decent quality. They look great! The bodies are cast like pretty much all the others I have worked with in the past. The threads are very sharp and clean with minimal internal restriction. They look to be very well designed, and considering they are direct acting valves, they will work with zero pressure. That means you can use them in a gravity system without a pump!
I wouldn't hesitate to say that the quality is equivalent to the $234 ASCO's that I currently have that won't work with a low-pressure system!
He carries 1/4" up to 1" in pretty much all coil configuration one would need. 12VDC, 24VDC, and 120VAC. Look for the brass valves with the Viton seals. They will handle boiling temps with no problem.
I have had several conversations via email with Esa. The customer service is great, especially considering these valves are only $33 or so. The models with the Viton seals are listed as 12VDC. Just email him or put the coil voltage you want in the comments field on the PayPal checkout and he will change out the coil to what you want.
