Rotary Valve Cavity Air Purge

Smoot offers the cavity air purge process on its entire line of rotary valves to reduce abrasion on the rotor, cylinder, and endplates. This patented design uses low-pressure air from the convey blowers and purges the material from the cavity between the shroud and the housing plates. This air serves two purposes: to prevent the product dust from reaching the shaft packing, and, more important to the life of the overall rotary airlock, it blows off material that would attempt to settle on the top flat surface of the closed end rotor.
