FCS300 Stainless Steel Spray Valve

Spray 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


The FCS300 is available on the Delta 6, PVA2000, PVA6000, and PVA350 Selective Coating Systems, can be retrofitted to any existing PVA system, or can be acquired for any manual spray application.
