Speedy dispensing
29 June 2016
Nordson EFD has introduced the xQR41 Series MicroDot needle valve with quick-release technology that allows full change out of wetted parts within seconds, reducing downtime and boosting productivity.

The company says the 60% smaller form factor than standard valves – 66mm length x 23.7mm diameter – enables multiple valves to be mounted closer together. A specially designed QR clasp secures the fluid body to the air actuator and can be removed without tools.
The pneumatically-operated, adjustable valve applies precise micro-deposits as small as 150µm (0.15 mm) of low- to high-viscosity fluids. The 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.
