xQR41 MicroDot Valves

The xQR41 Series MicroDot™ needle valve features QR (Quick Release) technology, a 60% smaller form factor, and modular design for new levels of customization in precision fluid dispensing.

Ideal for automated assembly processes, the xQR41 MicroDot valve’s smaller dimensions allow it to dispense in tighter spaces at more complex angles. The added flexibility to mount more valves per fixture plate delivers greater output per batch.

In addition, its patented QR (Quick Release) clasp allows easy removal of the fluid body to replace wetted parts in seconds, vs. traditional change outs which take minutes. The clasp design eliminates the need to remove the mounting fixture or use any tools during valve maintenance.

The xQR41 needle valve’s exchangeable modular design makes it easy to adapt to a variety of specific dispense applications. Its configurability with PEEK wetted parts, BackPack™ Valve Actuator, mounting block, or 90° low-profile air inlet actuator, among other interchangeable parts, makes it uniquely accessible and cost effective.

Features

  • 60% smaller form factor than conventional needle dispense valves
  • Consistent microdots as small as 150 µm (0.15 mm) (0.006”) diameter
  • Exchangeable, modular design
  • Zero dead fluid volume

When the application of larger deposits is required, the xQR41V Series needle valve provides all the benefits of the xQR41 and is compatible with the full range of Nordson EFD dispensing tips.
