43 Auger Valve 794 Series The 794 auger valve uses screw feed technology with precision time and pressure controls to dispense accurate, repeatable amounts of particle- filled materials. The 794 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. Features and Benefits • Adjustable auger speed • Two motor types—brush or brushless • Fixed head version for lines and stripes • Sliding head/footed tip version maintains consistent dispense gap when dispensing on surfaces with irregular height.
