Adjustable vacuum release valves?
(OP)
Are there adjustable vacuum release valves?
What I mean is "Can a valve be set to remain closed at negative pressure of 11 psig and open at say negative 15 psig.
The application involves a siphon that will operate at a negative pressure at the apex. I'm concerned the pipe will collapse when the siphon is "broken".

there are several companies producing this kind of devices:
www.protego.com
www.protectoseal.com
Look in www.che.com , buyers guide, under "Valves, vacuum relief" about 50 suppliers.
I hope you do not really need minus 15 PSI, it is below absolute zero

Working with a lot of vacuum, I can really say my job sucks.
