Using OS Valve for Turbines Without Pressure Control

control your air so way this works is I screw this I can slowly reduce this down and as I do this is your air passage that's coming through the gun here and as I reduce as I increase this screw it's sending this plunger into the air passageway and slowly restricting the air flow so you're not only reducing the pressure but you're also reducing the volume of the air through the spray gun as well which is important to do both so I can use this as a way to sort of cheat my air pressure and reduce the air pressure through a fixed powered turbine system but again for most of our systems that we have nowadays uh most of them all have variable speed control on them and so we just back it all the way out and we're more or less using it as a blanking cap so I I use I have two units
