781S General Purpose Spray Valves

Availability: In Stock

The 781S Series general purpose spray valve provides exceptional control for reliable, consistent coatings of low- to medium-viscosity fluids using Low Volume Low Pressure (LVLP) technology.

It offers adjustable fluid flow, adjustable nozzle air, and post-air cutoff to provide superior spray control without waste, mess, or overspray. This means fluid goes exactly where it's needed, improving consistency with reduced fluid use and cleanup costs.

Fluid can be reliably dispensed in microliter to milliliter amounts, in round patterns with diameters ranging from 4.3 mm (0.17") to 50.8 mm (2.0"), and in fan patterns up to 165.1 mm (6.5") wide.
