HVLP Overspray Control Valves | Tips Spraying With An HVLP Gun

What happens here

Reiterating the earlier advice, for most modern HVLP systems that feature variable speed control, the OS control valve on the spray gun should be fully backed out. Adjusting pressure directly on the turbine offers far greater accuracy, often down to one-tenth of a PSI, compared to the less precise mechanical adjustment through the gun's valve. This approach ensures optimal performance and efficiency from your painting system.

Goal: Emphasize that modern turbines offer superior, more accurate pressure control (1/10th PSI) than the gun's OS valve, which should remain fully open.

What they say

Hide

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 I got a a Precision five and I got a Precision six so pretty much I can actually remove that put a cap on it and um and I'd actually be better off than actually actually using it then maybe yeah you wouldn't need to use it at all because remember with your precision machine you have the control to be able to um reduce that pressure to an accuracy of onet of a PSI so that's going to be way more accurate than trying to reduce it through um a mechanical means of reducing pressure through the gun so there you have it
