GV-697 – Non-atomizing Film Conformal Coating Valve

Precision conformal coating dispensing moisture-proof material into thin film patterns

The GV-697 conformal coating valve is specifically engineered to administer moisture-resistant coatings onto PCBs at a reduced flow rate. Its unique square-cut nozzle design guarantees exceptional stability and prevents any excess spray, resulting in a faster and mess-free dispensing process.

Features and benefits

  • Consistent and precise coating
  • No overspray or misting
  • Customizable spray quality
  • Gentle and controlled spraying

VALVE OPERATION

Input air pressure retracts the piston needle from the nozzle seat, allowing fluid to flow. (Figure 1)

Once the cycle is completed, the piston spring returns the piston needle back to its position to shut off the fluid. (Figure 2).
