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.
Main features are:
• Adjustable flow rate
• I/O interface
• Adjustable auger speed
• 8 pitch or 16 pitch auger
• Two motor styles — brush or brushless
• Low-maintenance design
• Fast, tool-free latch release of wetted parts
• Sliding head / footed tip components for surface
irregularities and to maintain consistent dispense
gap height
• Fixed head version for lines and stripes
