HVLP Overspray Control Valves | Tips Spraying With An HVLP Gun

What happens here

The presenter explains the historical context behind the OS control valve's development. Traditional turbine systems lacked any mechanism to control air pressure or vary the motor speed. This limitation meant that spraying thin materials often resulted in full pressure, leading to significant overspray and wasted material. The OS valve was designed to overcome this by providing a way to restrict airflow through the gun, functioning as a 'cheater valve' for fine-tuning pressure when the turbine itself couldn't.

Goal: Learn that the OS control valve was created to compensate for older turbine systems' lack of built-in air pressure control, preventing overspray and material waste.

What they say

Hide

system traditionally turbines have not had any way to control the air pressure or vary the speed of the motor and so you were able to you weren't able to reduce the amount of pressure so if you were spraying a very thin material you'd have to spray it with the full P pressure which would give you a little bit more overspray and a little wasted more wasted material so by having this little device in the in the gun we can actually restrict the air flow through the spray gun and be able it's kind of like a cheater valve on your compressed air guns right so it's a way to kind of more fine-tune it uh so we really invented this for turbines that don't have pressure control on the machine itself most of our turbines now Apollo
