The EFD Nordson BackPack Valve Actuator has been designed to improving productivity of EFD dispense valves. It helps to produce more products in less time by cycling select EFD valves 2–3 times faster than previously feasible. The faster valve actuation also enables to produce the smaller fluid deposits required in the assembly of many of today’s advanced products, such as medical devices and portable electronics. Incorporating advanced miniature solenoid technology. The valve actuator 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. The EFD dispense valves are used on automated production lines to apply adhesives, lubricants and other assembly fluids in accurate, repeatable amounts. Edited by: Constanze Schmitz
