794 Valve Auger valve system for precise, consistent fluid application. The 794 Series auger valve system is designed to make precise, repeatable deposits of solder paste. Motor Electrical Cable to the 7094 Controller Syringe Adapter Assembly 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. 794 Series Auger Valves Optimum Syringe Reservoir 3cc to 55cc Motor Chamber The 794 Series auger valves are designed for use with the 7094BL and 7094DC controllers or XYZ dispensing robots like the EFD TT automation system. 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 7094BL and 7094DC controllers regulate 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. Reduction Gear Assembly Features and Benefits • Accurate, consistent output • Adjustable flow rate Syringe Clamp • I/O interface • Adjustable auger speed Supply Hose • 8 pitch or 16 pitch auger TT Mount • Two motor-styles – brush or brushless • Low-maintenance design Auger • 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 Size: 237.4 mm x 31.7 mm diameter (9.35" length x 1.25") Weight: 544 grams (19.2 oz) Fluid chamber: Type 440C hardened stainless steel Auger: Type 440C hardened stainless steel “U” cup: Filled PTFE, spring energized Liquid feed fitting: Type 304SS #10-32x5/32" (push-in optional: polypro) Auger speed: 250-400 RPM based on voltage input Auger pitch: 8 and 16 pitch auger Input Voltage: 12-24 VDC (<10% ripple) Input Air: 0-30 psi (0-2.07 bar) clean and dry Maximum Acceleration: 2g All stainless steel parts are passivated.

794 Valve Auger valve systems The 794 Series auger valves are available in brush and brushless motor configurations. Either configuration can be used with XYZ dispensing robots like EFD’s TT automation system. NOTE: For Brushless Motor style 794 Auger Valves, To I/0 connector pins 7&8 use 7094BL controller. For Brush Motor style 794 Auger Valves, use 7094DC controller.
