Recirculation for E450
Hello, In all my other cars I have a vent recirculation switch so that when I am behind a stinky vehicle I can shut off the outside air. I cannot find this in my Class C Ford E450. Is this so...

I think your interest in this would be better served with adding a switch to the compressor clutch, vs. a valve to vacuum controls.
Does this mean that you would use the max A/C switch but then disable the compressor?
Yes, but there's really no need to do this if you can settle on a temperature with the compressor still running.
More I think about it, there's a problem: If you disable the compressor, the "vent" temperature is going to climb, because the Heater Core is still HOT. Then you'd have to put a water cutoff valve in the heater line, and that could affect circulation in the engine cooling system.
Best to leave it as-built and set temperature with the Knob.
