Aseptic Spray Valves

Nordson EFD's 784S-SS aseptic spray valve features a fluid flow path that is free of any entrapment areas—a critical consideration in sterile and aseptic fluid applications.

Using Low Volume Low Pressure (LVLP) technology, the 784S-SS aseptic spray valve system accurately controls the application of most low- to medium-viscosity fluids. The 784S-SS aseptic spray valve uses a small gauge dispensing tip to produce uniform round spray patterns between 0.130" and 0.75" in diameter. For a wider area of coverage, the 784S-SS-F aseptic spray valve with fan air cap is available.

The unique design of the 784S-SS aseptic spray valve provides a fluid flow path free of any entrapment areas which is critical for sterile and aseptic fluid applications. Wetted parts are 316L stainless steel and PTFE, which are suitable for CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes.

The complete valve system includes the 784S-SS valve, ValveMate 8040 controller, fluid reservoir and dispense tip.
