The Valve
The part number for this item is #4HN46 And can be found at the Grainger Industrial Supply page at www.grainger.com . You will find all the specs on this item. The quick couplers did not come with the valve, this you will have to buy them separately. I got them at Harbor Freight Tools.
I also purchased the needed air line at Harbor Freight Tools.
Air outlet (female quick coupler)
Air inlet (male quick coupler)
All this vales does is open and close, you will not have any control of air flow. More than likely you will have to control it from the compressor.
