Rotary airlock valves

Rotary airlock valves


  • Rotary airlock valves serve as a "lock" to prevent air loss in pressure style and vacuum style pneumatic conveying systems. GREENING designed and fabricated rotary airlock valves are critical components that perform vital material handling functions.

Application Area:

  • GREENING rotary airlock valves are used in a wide range of applications where minimizing system air loss is necessary while transferring material between vessels with differing pressures.
  • Rotary airlocks control the feed rate and minimize air leakage between equipment above and below the valve with differing levels of pressure or vacuum.
  • They are also used as feeder valves to meter the flow of material between vessels with equivalent pressures.

Salient Features:

  • One-piece rotors with cast machined housings for a superior seal.
  • Permanently lubricated outboard bearings ensuring low maintenance.
