Auger valves use screw-feed technology with precision time and pressure controls to dispense accurate, repeatable amounts of particle-filled materials, thermal interface materials (TIM), or other highly abrasive pastes. The auger assembly can be easily replaced to change the gap size as needed. The robust tungsten carbide (TC) auger screw and fluid body liner on the 794-TC valve resists wear from highly abrasive pastes to ensure long valve life.
