FCS300 Stainless Steel Spray Valve

Selective Conformal Coating Valves


Stainless Steel Spray Valve

The FCS300 spray valve provides a repeatable, concentrated coating film in pattern widths ranging from 0.25” to over 2”.

The atomized spray process resulting from the FCS300 will produce conical (round cap) or fan-shaped (flat cap) patterns with transfer efficiencies in excess of 99%. The FCS300 features a micrometer flow adjustment that makes fine tuning of your process easier than ever.

The FCS300 has many integrated features including:

  • Low pressure, low volume atomized process
  • 300 series stainless steel fluid body for superior material compatibility
  • Interchangeable spray cap offers fan and oval-shaped patterns
  • Micrometer flow adjustment with lock nut
  • Divorced valve design prevents contamination of the air section
  • Compatible with all commercially available conformal coatings
  • Wide viscosity range offers versatility for virtually any spray application
