Auger valve system for precise, consistent fluid application
16 pitch, brush motor, and fixed head
The 794 Series auger valve system is designed to make precise, repeatable deposits of solder paste. By integrating screw feed technology with precise control of dispense time, syringe pressure and auger speed, the 794 Series system ensures consistent deposits without damage to the metal alloy particles in the solder paste.
The 794 Series auger valves are designed for use with ValveMate™ 7194 controllers and EFD’s automated dispensing systems. During operation, air pressure applied to the syringe of solder moves paste into the path of the auger. As the auger rotates, solder paste moves along the threads and out the dispensing tip. The VM7194 controller regulates feed pressure so that there is enough pressure to keep the valve primed with solder without forcing it past the auger, and controls dispense time and auger speed.
