A good app (IF you get the speed up with servo and/or valve changes, as I suggested above).

Nope, you can't use a kit valve for directly controlling vacuum. If you look at the kit valves specs, they are ALL "piloted". That means they need positive air pressure on their inputs (of several TENS of PSI), just to operate. Therefore, they can only control air going INTO your Vacuum Generator, and the VG must be directly connected to your suction cup. (Which DOES work...)

But if you are intending to generate vacuum with a kit motor, be aware that none of the kit valves are capable of directly controlling vacuum, because even a perfect 14.7 PSI differential across them isn't a sufficient pilot pressure to allow them to operate.
