The Nordson EFD BackPack™ is a fast-acting, compact valve actuator that provides faster response time and reduces the possibility of variations in shot size due to a fluctuating plant air supply or different air line lengths.

The BackPack utilizes advanced miniature solenoid technology that makes it possible to achieve valve actuation speeds as short as 5-6 milliseconds, and cycle rates as high as 800 per minute. It features a compact, low-profile design that facilitates center-to-center mounting and is made of lightweight materials for easy end-of-arm installation. The Backpack is available preinstalled on new valves, and can also be ordered separately to retrofit existing valves.
