787MS-SS-RC RECIRCULATING MICROSPRAY VALVE

PN: 7026680

MICROSPRAY VALVE FOR PRECISE, UNIFORM SPRAY PATTERNS

This model is for applications with particle-filled fluids that must be kept in suspension, or fluids that must be kept circulating to prevent separation.

The 787MS-SS Series is a precision spray valve that uses low volume low pressure (LVLP) technology to produce uniform spray patterns between 3.3 mm and 19 mm (0.130 and 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 over 30% smaller than Nordson EFD’s standard spray valve configuration. Between shots the valve needle seats in the hub of the dispensing tip, virtually eliminating dead fluid volume.
