Rotary Valves

Rotary valves are used for feeding bulk materials into pneumatic conveying systems and discharging out of hoppers and silos. Rotary valves installed on the outlet of a dust collector, cyclone, or mechanical conveyor, this piece of equipment ensures air tightness between two differential pressures.

The design of our rotary valves allows for quick and easy maintenance. Our rotary valves are highly regarded as top-quality products in the plastics, chemical, food and minerals industries around the world. Our rotary valve also set standards at high pressures and with regard to wear protection. We carry the largest product range worldwide, and are able to fulfil all requirements of a modern bulk handling plant in all sizes and pressure ranges.

  • Rotary valves for powders:
    • The advantages of our application know-how: Large inlet. Restriction free product flow. High degree of fill.
  • Rotary valves for pellets:
    • The advantages of Coperion valves for pellets: Patented anti-chopping inlet geometry. Safe starting under full product load.
