Micro valves enhance automated assembly

Small 66 x 23.7 mm profile.

403_Nordson_EFD_xQR41_valveNordson EFD’s xQR41 MicroDot needle valve is 60% smaller than standard valves and is equipped with an exchangeable modular design that enhances customization options and process control.

The company’s Quick Release technology allows full change outs of wetted parts quickly to reduce downtime and enhance productivity.

Its small 66 x 23.7 mm profile allows multiple valves to be mounted closer together to increase output per batch, improving production throughput. The valve dispenses in tighter spaces and at more complex angles. Weighing only 141.4 g, it reduces tooling payload to increase actuator arm speed, but also reduces tabletop automation (TTA) motor and belt wear.

The pneumatically-operated, adjustable valve’s small form factor also creates a smaller wetted path, which reduces retained volume to minimize fluid waste. It’s fed from a variety of reservoirs, syringe barrels, external cartridges or tanks.

It applies precise micro-deposits as small as 150 µm of low- to high-viscosity fluids onto a substrate. An exchangeable modular design is configured with stroke adjustable or non-adjustable cap, BackPack valve actuator, low-profile mounting block, and 90-degree air and fluid inlet fittings.

The fluid body is aligned and locked at 360 degree intervals for mounting, positioning and fluid inlet alignment needs.

Nordson EFD is a manufacturer of fluid dispensing systems based in East Providence, RI.
