not certain if this image uploaded but its 

3M Accuspray Air Flow Control Valve, 16573

I'm looking to see if I can use this with a standard Iwata airbrush, I use this with a mini spray gun for large priming by Iwata with larger connections

i sent the image to postimage but Im unable grasp exactly how it works 

 

 

Check down below in the tools technics and references sections.  There is a forum on painting and airbushing.  Ask there.
