Nordson EFD has revealed a new fully exchangeable and modular concept in non-contact and contact needle dispensing of assembly fluids. The PICO xMOD Valve system uses a high-tech, robust, durable piezoelectric actuation technology for continuous operation at speeds of up to 500cycles/second.

"Our new PICO xMOD offers the only tool-free release and installation of the Valve Seat assembly," explains Claude Bergeron, product line manager, Nordson EFD. "Wetted parts are conveniently and quickly exchanged and serviced. If a part fails, just the worn part needs changing, eliminating the expense of a whole new valve assembly. The ability to swap one xMOD component part for another lets the manufacturer toggle between different applications and fluids, offers flexibility, makes a significant reduction in production down time, and saves time and money."

The PICO xMOD can produce deposits as small as 2nano liters with exceptional deposit accuracy and superior process control. The non-contact jet valve makes it possible to apply fluid in hard-to-access areas or onto uneven or delicate substrates for applications in electronics, automotive, life sciences, solar, and a range of other industrial dispensing applications.

All five major xMOD valve components, the Piezo Actuator (PA), the Valve Seat (VS), the Fluid Body (FB), the Cartridge ball/stem assembly (CR), and Heater Set (HS), are fully interchangeable and easily assembled for each specific application and quickly disassembled for easy cleaning, repair, or maintenance. Each part can be removed and exchanged in seconds, eliminating production down-time and significantly increasing productivity.

Each EFD PICO xMOD component can be individually selected to accommodate particular fluids and applications. All the components are engineered to work together as a complete, integrated system that produces exceptionally fast, accurate deposits of a wide range of fluids.
