This unique marking system eliminates the clogging, maintenance and downtime encountered with standard marking systems by using a recirculating pump to keep pigments in suspension and a programmable air delay after each cycle to clean the spray nozzle. This MicroMark system can be used to color-code similar components, indicate pass/fail, or show production or test status. It can be activated manually or interfaced with other systems to mark at scheduled intervals. Features and Benefits • No clogging, dripping or drying out • Keep pigments in suspension • No mist or overspray • Consistent size and placement For use with: Marking Inks Paints Other Fluids that Separate The complete recirculating spray marking system includes the 781RC-SS spray valve, the ValveMate 8040 controller with single in-line solenoid, recirculation pump enclosure assembly, 1-liter reservoir and all necessary air and fluid hoses with fittings. Available in two nozzle sizes. See below. 7013915 Recirculation spray valve with 0.36 mm (.014") diameter nozzle. Round pattern, narrow angle. All metal parts are passivated 303 stainless steel. 7013769 Same as #7013915 recirculation spray valve but with 0.71 mm (.028") diameter nozzle. Round pattern, narrow angle. All metal parts are passivated 303 stainless steel. For fluids not requiring recirculation, select MicroMark System MM781-SYS. See below. 7023895 Includes spray valve, ValveMate 8040 controller, solenoid valve kit and 1-liter tank reservoir. www.nordsonefd.com info@nordsonefd.com USA & Canada 800-556-3484 Europe +44 (0) 1582 666334 Asia +86 (21) 3866 9006 SPRAY MARKING SYSTEM Electric Constant Air Pulsed Air Fluid
