You got it. I was going to make a mini-MBC type valve for it, but I found a cource for ball and spring check valves with viton seals available in a range of seat/spring pressures and flow rates- so I tested it with an MBC hooked as a bleeder so I can adjust it to get it close, measured the psi of the seat pressure and ordered an assortment of check valves going up and down from there and found the one that was best suited all around for the application.

Cool! Although there may be a market for the adjustable version someday...who knows.
