System Overview – Valves Nordson EFD’s PICO piezoelectric jet dispensing systems have four components: (1) a PICO valve, (2) a DCON valve driver, (3) a PICO controller and (4) a fluid reservoir. All components are engineered to work together as a complete, integrated system that produces exceptionally fast, accurate deposits of a wide range of fluids. Jet Valves (for Non-contact Metering) Rod Piezoelectric Actuators Fluid Path Valve Closed Sealing Ball Piezoelectric Actuators Fluid Path Valve Open Sealing Ball PICO jet valves incorporate two piezoelectric actuators composed of stacked...

Needle Valves (for Contact Metering) PICO needle dispensing systems provide exceptional deposit accuracy and process control for a wide range of fluids. Fast-acting piezoelectric actuators make it possible to apply extremely small dots and well-defined lines with precise control of the beginning and end points. An adapter attached to the nozzle plate allows the use of precision dispensing needles. Slider Valves (for Solder Paste and Highly Filled Adhesives) Slider valves are designed for needle dispensing of particle-filled fluids and incorporate two sliding ceramic plates, each with a...

System Overview – Drivers and Controllers DCON Valve Drivers Piezoelectric dispense valves are powered by valve drivers that use an amplifier to generate the signal for the piezoelectric actuators. DCON drivers are available with or without temperature controllers. The temperature control version is designed for use with valves that incorporate a heater to keep the fluid at optimal jetting viscosity. DCON valve drivers: • Supply voltage to actuate the piezoelectric elements in the valve • Control the temperature of the valve heater (select models) • Keep the valve closed in case of power...

Features/Benefits Nordson EFD’s PICO dispensing systems combine high production speed with exceptional accuracy and process control. Three configurations are available to handle virtually any application: Non-contact jet valve systems make it possible to apply fluid in hard-to-access areas or onto uneven or delicate substrates where a dispensing needle cannot be used. Needle valve systems produce extremely small dots and well-defined lines with precise control of beginning and end points. Slider valve systems provide fast, precise application of solder paste and other particle-filled...

Fluids PICO Fluid Reservoirs and Dispensing Needles PICO reservoir systems are designed to function with Nordson EFD Optimum® barrel and cartridge components as a complete, integrated system that improves yields and reduces costs in fluid dispensing processes. A comprehensive selection is available to meet the fluid capacity needs of your jetting or needle valve applications. Choose EFD Optimum reservoirs for standard operating fluid feed pressures under 7 bar (100 psi). For fluid pressures greater than 100 psi, select PICO stainless steel reservoir retainer systems that accommodate...
