PICO® Pµlse™ Valve System The Latest Advance in Precision Jetting Technology The PICO Pµlse non-contact jet valve delivers faster, more precise dispensing over smooth and uneven surfaces with less turbulence for greater fluid deposit consistency, placement, and process control. Dispense micro-deposits as small as 0.5 nL at up to 500Hz continuous with 1500Hz maximum bursts – an industry best in class. Variable stroke provides better stroke control, making it possible to set very exact, repeatable deposit quantities. Improved close time, in addition to faster full stroke open time, make Pµlse one of the most robust jet dispensing valves on the market. Its innovative tool-free latch mechanism allows easy removal of wetted parts for fast, simplified serviceability and maintenance. Its modular design and exchangeable parts make it possible to dispense a wider variety of fluids with low to high viscosities. This makes it suitable for a wider range of applications, so it can meet changing dispensing demands as your business grows. Jet lines onto uneven surfaces with greater precision. Features • Exchangeable, modular design for greater configurability. • Tool-free latch for easy removal of fluid body. • Variable stroke for precise dispensing control. • Makes micro-deposits as small as 0.5 nL. • Dispenses at 500Hz continuous, with 1500Hz max bursts. Benefits • Capability to jet low- to high-viscosity fluids provides the flexibility to meet changing dispensing needs. • Tool-free latch allows fast, easy serviceability and reduces downtime. The PICO Pµlse valve removes the barrier between speed and accuracy. Jet UV-cure adhesives onto printed circuit boards with greater repeatability. • Industry-leading accuracy in deposit consistency, repeatability, and placement. • Eliminates Z-axis movement for significantly faster production speeds. • Improved thermal performance for greater viscosity
