Nordson EFD introduces needle valve series

Nordson EFD, a Nordson company, has just introduced the xQR41 Series MicroDot™ needle valve. The valve features a 60 percent smaller form factor than standard valves, 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 new valve expands manufacturing opportunities for multiple applications and industries.
The xQR41 valve’s small profile of 66mm length x 23.7mm diameter enables multiple valves to be mounted closer together for greater output per batch, increasing production throughput. The needle valve can dispense in tighter spaces and at more complex angles. Weighing only 141.4g, the xQR41 valve reduces the tooling payload. This not only means faster actuator arm movement and improved positioning stability, but also reduced tabletop automation (TTA) motor and belt wear. The xQR41’s small form factor also results in a smaller wetted path, resulting in less retained fluid volume. It can be fed from a variety of reservoirs, syringe barrels, external cartridges or tanks.
