Nordson EFD’s new BackPack Valve Actuator improves dispense valve speed and accuracy

Nordson EFD has introduced a new device for improving productivity of EFD dispense valves.

Called BackPack Valve Actuator, it enables more products to be produced in less time by making it possible to cycle select Nordson EFD valves 2-3 times faster than previously feasible.

The faster valve actuation also enables the production of smaller fluid deposits in the assembly of many advanced products, such as medical devices and portable electronics.

Incorporating advanced miniature solenoid technology, the BackPack mounts the solenoid used to open and close the valve directly on the valve’s air cylinder, rather than on a separate fixture.

This makes it possible to achieve valve actuation speeds as short as 5-6 milliseconds and cycle rates as high as 800 per minute. In contrast, typical valve actuation speeds and cycle rates are 15 milliseconds and 400 cycles.
