42 Nordson EFD jet valve systems offer unparalleled speed and accuracy in non-contact dispensing, even for your most challenging applications. Jetting, or non-contact dispensing, allows manufacturers to dispense small amounts of fluids at faster speeds without sacrificing accuracy. The results include reduced waste, rework, and rejects, and higher throughput yields. About Piezo Technology PICO® jet valves incorporate a piezoelectric actuator composed of stacked ceramic coins that expand and contract in response to changes in voltage supplied by the PICO controller. The piezo actuator connects to a vertical rod that mates with a tappet stem within a spring-energized “jetting” cartridge. The tappet stem has a wear-resistant ceramic sealing ball at its lower end. When the valve is closed, the ball is seated in the valve nozzle plate to prevent fluid flow between cycles. The unique precision engineering and machining of these critical components create an exceptional dispensing valve with the ability to apply precise, accurate micro-deposits of assembly fluid. When voltage is applied to the actuator, the rod and cartridge sealing ball are raised so that the pressurized fluid can flow to the nozzle. When the voltage is changed, the rod and tappet stem sealing ball descend rapidly to “jet” the fluid out of the nozzle and onto the substrate. Pneumatic Jetting Liquidyn® pneumatic jet valves deliver precise, consistent noncontact dispensing of low- to high-viscosity fluids and feature easily exchangeable dispensing nozzles to meet a wide range of application requirements. Rigorously tested to withstand highly-industrial environments, Liquidyn pneumatic jet valves also feature a low cost of ownership. Precision Jetting Valve Systems PICO / Liquidyn
