MicroDot needle valve is 60% smaller than standard

Featuring a 60% smaller form factor than standard valves, the xQR41 series MicroDot needle valve has been introduced by Nordson EFD. It includes an exchangeable modular design for greater customisation and process control and a Quick Release (QR) clasp that allows easy removal of the fluid body to replace wetted parts in seconds.

The xQR41 series expands manufacturing opportunities for multiple applications and industries, especially those related to wireless devices, sensors, mobile phones and other high-end electronics.

The valve's small size of 66x23.7mm (2.60x0.93") enables multiple valves to be mounted closer together for greater output per batch, increasing production throughput. Suited for automated assembly processes, the needle valve can dispense in tighter spaces and at more complex angles. Weighing only 141.4g (5.0oz), the valve reduces the tooling payload which enables faster actuator arm movement, improved positioning stability as well as reduced tabletop automation motor and belt wear. The xQR41's small form factor also results in a smaller wetted path, retaining a lower fluid volume, which minimises waste. It can be fed from a variety of reservoirs, syringe barrels, external cartridges or tanks.

The valve's unique QR clasp secures the fluid body to the air actuator and can be removed with a turn of a thumbscrew. No longer needing to remove the entire actuator or valve assembly from mounting fixtures, a full change-out takes seconds, not minutes. This is particularly important in applications with fluids that have a curing time where the wetted part must be removed as quickly as possible and returned to operation.

The pneumatically-operated, adjustable valve applies precise micro-deposits as small as 0.15mm (0.006") of low- to high-viscosity fluids onto a substrate. The xQR41's exchangeable modular design can be configured with stroke adjustable or non-adjustable cap, BackPack valve actuator, low-profile mounting block and 90° air and fluid inlet fittings. The fluid body can be aligned and locked at 360° intervals to accommodate mounting, positioning and fluid inlet alignment needs. It can be installed on many automation platforms.

Claude Bergeron, Product Manager, Nordson EFD, comments: "With rapid interchangeability, a smaller form factor and infinite configurability, Nordson EFD's xQR41 MicroDot needle valve not only offers new possibilities for fluid dispensing, but it also saves time and costs and increases productivity."
