Swirl Valve
Swirl valves are a critical part of your spray gun and are subject to the most
wear. Water based paints are abrasive and can wear a swirl valve very quickly.
To tell if your swirl valve is worn, look at the sealing block – it should be clean
and the edges not rounded or ‘furred’.
A worn swirl valve can give the following problems:
• Poor atomisation
• Spitting
• Irregular Spray
A badly worn swirl valve will stop the gun from picking up paint. Swirl
valves cannot be claimed under warranty. Ensure that you use the correct
swirl valve for the type of paint you are spraying
Swirl valves are color coded for different uses and different model spray guns.
White Swirl Valves are for water based paints and black ones for oil based paints
