GV-690CD – Non-contact dot Triple Mode Spraying Valve
The non-contact dot or spray line can be chosen by using only one valve.
The GV-690CD is specifically engineered to distribute conformal coating substances in three distinct manners: non-contact dot, spraying, or line dispensing. This ensures effective coverage of targeted areas.
Features and benefits
- Consistent and precise coating
- No overspray or misting
- Customizable spray quality
- Gentle and controlled spraying

VALVE OPERATION
Non-contact dot dispensing
Input air pressure retracts the piston needle from the nozzle seat, allowing fluid to flow. (Figure 1).
The piston needle’s instant shut-off creates non-contact dots. (Figure 3)
Spraying
At the same time as (Figure 1), the nozzle air flows around the air cap to atomize the fluid into fine droplets. (Figure 2)
Once the cycle is completed, the spring returns the piston needle back to its position to shut off the fluid. (Figure 3)
Line Dispensing
Input air pressure retracts the piston needle from the nozzle seat, allowing fluid to flow to create a bead for the duration that it remains open. (Figure 1)
Once the cycle is completed, the spring returns the piston needle back to its position to shut off the fluid. (Figure 3)
