Would the 12 valve pneumatic bank contained within the aux box work with negative pressure (vacuum pump) lines or only high pressure lines?
The bank is on a manifold that we feed with positive pressure, so you can’t plumb directly into a particular valve, so even if it did work you can’t physically plumb directly into the valve.
You can however use any of the relay outputs, and the 24V supply that’s in there to hook up another independent valve if you want.
I don’t know about the avid valves, but mine wouldn’t anyway, because they use the air pressure to actuate the valve body too.
Thanks for confirming. I’m looking to automate my AirWeights tables in the future using the relay to control the pump and individual valves to cover various zones
