What you need is a 3 port, 2 way solenoid valve. The 3 ports allow it to bleed vacuum when in the "vacuum removed" mode so the shut off is ready to reapply. I got mine from Peter Paul but it was a bit hard to order. If you go that way I can look up the part number.

Sometimes the instrumentation plumbing that I did in my working life comes in handy!
