794 / 794-TC Auger Valves

The 794 Series auger valve makes precise, repeatable deposits without damage to the metal alloy particles in fluids such as solder paste and silver epoxies. For highly abrasive fluids such as thermal interface materials (TIM), use the 794-TC Auger Series with tungsten carbide wetted parts.

Using screw feed principles combined with precision time and pressure controls, the 794 Series system ensures consistent deposits while eliminating damage to particle-filled fluids. It is available with two motor types – brush or brushless. The brushless motor is ideal for high speeds and high cycle rate microdot dispensing. The 794 Series also includes a sliding head/footed tip feature that maintains a consistent dispense gap when applying fluids to surfaces with irregular heights.

The 794-TC Series auger valve system is designed to make precise, repeatable deposits of thermal interface materials and other highly abrasive pastes. It’s designed with a brush motor ideal for lines and stripes with dispense cycle rates up to 60 to 90 shots per minute. The valve’s tungsten carbide construction provides long valve life.

The 794 / 794-TC Series auger dispense valves can be supplied with solder paste or thermal compounds from prefilled syringe barrels or cartridges.
