General Purpose Spray Valves

781S Series general purpose spray valves use Low Volume Low Pressure (LVLP) to apply consistent coatings of low- to medium-viscosity fluids exactly where needed. The combination of adjustable fluid flow, adjustable nozzle air and post-air cutoff provides excellent spray control.

This precision spray valve uses Low Volume Low Pressure (LVLP) technology to apply a uniform coating of material without waste, mess or overspray. By applying a fine, even spray exactly where needed, 781S Series valves improve consistency, keep production areas cleaner and reduce fluid use.

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

The complete valve system includes the 781S spray valve, ValveMate 8040 controller and fluid reservoir.
