784S-SS Aseptic Spray Valves

The 784S-SS aseptic microspray valve, with FDA-compliant wetted parts, features a fluid flow path free of entrapment areas, ideal for sterile applications.

Using Low Volume Low Pressure (LVLP) technology, the 784S-SS valve produces uniform spray patterns between 3.3 mm (0.13”) and 19.1 mm (0.75”) in diameter. It accurately controls the application of most low- to medium-viscosity fluids. For wider coverage, the 784S-SS-F model includes a fan air cap.

Its innovative design replaces a standard spray nozzle with a small gauge disposable dispensing tip, which concentrates the LVLP air used to atomize coatings into smaller spray patterns.

A fluid flow path that is free of entrapment areas makes the 784S-SS valve ideal for sterile or aseptic fluid applications. In addition, all wetted parts are 316L stainless steel and PFTE, making them suitable for CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes.
