The 781S Series universal spray valve provides exceptional control for consistent, reliable coatings of low to medium viscosity fluids using Low Volume Low Pressure (LVLP) technology.
provides adjustable liquid flow, adjustable nozzle air and after-air cut off to provide superior spray control without wasted, messy or spilled ink. This means fluid goes exactly where it is needed, improving consistency with reduced cleaning costs and fluid usage.
Liquids can be reliably dispensed in amounts from microliters to milliliters, in round shapes ranging in diameter from 4.3 mm (0.17″) to 50.8 mm (2.0″) and as fan-shaped up to 165.1 mm (6.5″) wide.
