Overview:
The 787MS-SS MicroSpray™ valve’s innovative design incorporates a small gauge disposable dispensing tip to apply a precise, uniform spray pattern more than 30% smaller than standard spray valves.

Using Low Volume Low Pressure (LVLP) technology it produces spray patterns as small as 3.3 mm (0.13”) and as great as 19 mm (0.75”) in diameter. A small gauge, 0.3 mm (0.013”) to 0.1 mm (0.004”), dispense tip replaces the standard spray nozzle, concentrating the LVLP air used to atomize coatings into smaller spray patterns.
The 787MS-SS increases throughput and allows greater process control, while reducing production costs and rejects. The valve needle seats in the hub of the dispensing tip, virtually eliminating dead fluid volume between shots.
Also available, the 781Mini™ Series spray valve delivers extremely uniform spray patterns as narrow as 1 mm (0.04”) wide in a 60% smaller form factor for the most exacting application requirements.
