HDA spray gun three-way valve HCV 13

The three-way valve of a liquid spray gun is a fluid control component used in spraying equipment, mainly used to switch the flow direction of paint, achieve rapid color change or prevent backflow, in order to improve spraying efficiency and stability. Based on the search results, the key information can be summarized as follows:

Electrostatic spraying adaptation: Some three-way valves are compatible with electrostatic spraying equipment (such as rotary cup spray guns), optimizing the coating atomization effect through automatic oil control function.

2、 Common types and application scenarios
Color changing valve (color switching valve): used for quickly changing different colors of paint, reducing downtime, commonly seen in automatic spraying lines for cars, furniture, etc.
Reflux three-way valve: maintains stable coating pressure in high-pressure systems to prevent backflow, suitable for robot spraying or precision coating.
Special three-way valve: such as electrostatic automatic oil control type, designed for gas rotary cups or liquid spray guns to improve spraying uniformity.

Typical application areas: including automated production lines for automotive manufacturing, industrial painting, furniture spray painting, etc.
3、 Key product characteristics and suppliers
Representative model: For example, the three-way valve HCV 13 used for  liquid electrostatic spray gun, supporting pressure fed coating supply; Or Taiwan made electrostatic oil control three-way valve, compatible with gas rotary cup spray gun.
During installation, it is necessary to match the spray gun model (such as a liquid electrostatic spray gun) and optimize pressure stability with a paint pressure regulator.
Regularly clean the inside of the valve to avoid coating solidification and blockage, which may affect the switching sensitivity.
When selecting, the appropriate valve model should be determined based on the type of spraying equipment (manual or automatic), the properties of the coating (such as water-based or oil-based), and the working pressure range.
