Auger Valves

Nordson EFD's 794 auger valve uses screw feed principles combined with precision time and pressure controls to dispense accurate, repeatable amounts of particle-filled materials such as solder pastes and silver epoxies.

By integrating screw feed technology with precise control of dispense time, syringe pressure and auger speed, the 794 series auger valve system ensures consistent fluid deposits without damage to particles within the fluid.

The auger valve is available with two motor types. Brush motors are best for lines and stripes, and deposit cycle rates under 60-90 shots per minute. Brushless motors are best for high-speed, high cycle rate microdot applications.

794 Series auger valves are designed for use with ValveMate™ 7094BL and 7094DC controllers, or Nordson EFD dispensing robots.

The 794 Series auger dispense valve can be supplied with solder paste from prefilled syringe barrels or cartridges. Contact a Fluid Application Specialist for more information.
