Does anyone have a resource for a manifold drain valve?

Hi! I couldn't find any references that addressed my problem in any of the history, so I'm posting it as a new topic. Winter is for repairs, so I've always been told. This project is on my To-Do list: I have an automatic misting system in my run. Works great EXCEPT for draining. The system is designed so that the timer turns the water on for 10-15 minutes out of every hour. At the end of each cycle, we installed 2 drain valves for irrigation systems. They were supposed to open when pressure drops below 3 psi. They stay open all the time, so we had to replace them with a faucets at the low point (end) which must be opened manually at the end of each cycle. I've worked with valves on aircraft, engine fuel systems mainly, which were spring-loaded open and closed by system pressure. When the fuel pressure dropped below 5 psi, the spring tension overcame the psi, the valve opened and the excess fuel in the systen drained. Does anyone know where I can get anything that works like this that can be installed in 1/2" pvc? Even if we have to think creatively about adaptation, any ideas will help. I know exactly what I want, but have no idea where I can get one. I don't want to buy one from Rolls Royce or Lockheed, either. That's a bit out of my price range! This is considered a high-pressure (60 psi) system. Anyone have any ideas?

Thanks,
Kathy

Try these folks:

Rather than search the catalog, go ahead and open up a chat session with one of their reps. I've found them to be very knowlegeable about their product lines. Good luck!

Did you see it there? That would blow me away! Or maybe I couldn't see the forest for the trees. I do a LOT of business with them. They are good and extremely helpful, but I just didn't see that valve there and it was the first place I looked. That's where I got the valves that didn't work for this system, too. Thanks!

No, I didn't see it (and wouldn't know it if I saw it...valves are Greek to me). But do try chatting directly with the rep. Just click on the link and open up the chat window. Nice folks who know their product lines.
