Includes spray tip kit, air hoses, fluid inlet fitting, barrel reservoirs, and adapter assembly for reservoir pressure. 7012549 787MS-SS Valve Does not accept Tip Centering Guide. Features and Benefits • High transfer efficiency • No overspray or mist • Consistent spray pattern • Faster throughput 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 0.3–0.1 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. TIP CENTERING GUIDE The Tip Centering Guide ensures proper alignment of the dispensing needle in critical spray applications. Order components separately.
