MicroSpray ™ Valve 787MS-SS The 787MS-SS precision spray valve uses Low Volume Low Pressure (LVLP) technology to produce uniform spray patterns between 3.3 mm (0.130") and 19.1 mm (0.75") in diameter. Innovative design uses a small gauge 0.3 mm-0.1 mm (0.013"-0.004") ID disposable dispensing tip in place of a standard spray nozzle. This concentrates the LVLP air used to atomize the coating into uniform spray patterns as small as 3.3 mm (0.130") in diameter—over 30% smaller than EFD's standard spray valve configuration.
