Frequently Asked Questions

Can it be used for PCB board coating?

Yes. It is suitable for general PCB conformal coating, where full-board or wide-area coating is acceptable.


It is not meant for selective or high-precision coating that requires fine-line precision around tight components.

What types of materials can I spray with it?

It works best with low-viscosity materials, such as:

  • UV adhesives

  • Thin conformal coatings

  • Solvent-based liquids

Thick, filled, or abrasive materials are not recommended.

Is this valve suitable for automatic production lines?

This valve is best for manual or semi-automatic setups.

For high-speed or fully automated lines, a higher-end precision spray valve is recommended.

Does it splash or make a mess when spraying?

When set up correctly, it produces a controlled circular spray with minimal splashing.
