Offset Rotary Airlock Valves for Mining & General Industry

UGES offset rotary airlock valves provide reduced-wear, extended-life material handling for abrasive mineral ores and industrial bulk solids. The offset rotor geometry minimizes the destructive grinding zone between rotor tips and housing, dramatically extending service intervals in highly abrasive mining applications.

Offset Rotary Airlock Valves Key Specifications

Rotor Design

Offset-mounted rotor with 8 heavy-duty blades and asymmetric housing clearance, reducing the abrasive grinding zone to extend rotor and housing life in mining service.

Housing Material

Ni-hard cast iron housing with optional ceramic lining and offset bore geometry, providing extreme abrasion resistance with reduced localized wear concentrations.

Inlet Size Range

200mm to 500mm heavy-duty flanged inlets with enlarged offset entry zone for reduced-shear intake of dense mineral ores and industrial bulk materials.

Pressure Rating

Differential pressure sealing up to 2.5 bar with offset geometry maintaining seal integrity while distributing wear more evenly across the rotor-housing interface.

Temperature Range

Standard operation from -20°C to 120°C, suitable for surface mining, underground operations, and general industrial applications requiring extended wear life.

Blade Configuration

8-blade offset rotor with tungsten carbide-tipped replaceable inserts and enlarged asymmetric pockets, maximizing wear life in highly abrasive mining and quarrying.

Industrial Applications

High-Abrasion Ore Handling
Handles quartz-bearing mineral ores with dramatically extended rotor and housing life compared to standard concentric designs, reducing maintenance frequency and cost.
Pelletized Product Gentle Metering
Meters mineral pellets and granular fertilizers without excessive crushing, preserving product sizing for downstream screening and quality specifications.
Extended-Life Bulk Powder Transfer
Provides long-service-interval airlock feeding for abrasive bulk powders like alumina, silica, and calcium carbonate in general industrial processing plants.
