Drop-Through Rotary Airlock Valves Key Specifications

SS 316 housings with Ra 0.8μm finish, 8-blade CIP-compatible rotors, and 150mm to 400mm sanitary connections. FDA-compliant PTFE seals ensure hygienic handling at up to 0.5 bar differential pressure.

Rotor Design

Open-end drop-through rotor with 8 mirror-polished stainless steel blades for complete product discharge, eliminating dead zones where food particles could accumulate.

Housing Material

SS 316 stainless steel housing with Ra 0.8 micrometer surface finish, compliant with FDA and EC 1935/2004 food contact regulations.

Inlet Size Range

150mm to 400mm inlet flanges with tri-clamp and DIN sanitary connections for easy integration into hygienic food processing conveying and packaging lines.

Pressure Rating

Differential pressure sealing up to 0.5 bar with food-grade PTFE shaft seals, preventing air ingress and moisture contamination in pneumatic conveying.

Temperature Range

Operating range from -20°C to 80°C, suitable for ambient and chilled food processing environments including frozen ingredient handling.

Blade Configuration

8-blade rotor with rounded edges and crevice-free design for CIP (Clean-in-Place) compatibility, enabling rapid sanitation between product changeovers.

Industrial Applications

Used in flour milling, spice blending, and sugar handling where hygiene is critical. Polished open-end drop-through design enables full product discharge and rapid CIP sanitation between batches.

Application 1

Flour Mill Pneumatic Conveying

Meters milled wheat flour from sifter discharge into pneumatic conveying lines feeding packaging and bulk storage, maintaining consistent feed rate and preventing dust escape.

Application 2

Spice Blending Line Feed

Provides contamination-free volumetric dosing of ground spices from storage hoppers into batch blending systems, with quick-disassemble design for allergen changeover.

Application 3

Sugar and Starch Handling

Feeds granulated and powdered sugar into pneumatic conveying and weighing systems, with ATEX-compatible sealing to mitigate dust explosion risk.
