Offset Rotary Airlock Valves for Insulation Manufacturing Plants

UGES offset rotary airlock valves provide gentle, low-damage handling for delicate insulation materials including expanded perlite, vermiculite granules, and lightweight calcium silicate particles. The offset rotor geometry reduces crushing forces to preserve the thermal performance properties of insulation feedstocks.

Offset Rotary Airlock Valves Key Specifications

Rotor Design

Offset-mounted rotor with 6 deep-pocket blades and asymmetric clearance, reducing crush forces on lightweight expanded perlite and vermiculite insulation granules.

Housing Material

Carbon steel housing with epoxy-coated internals and offset bore geometry, resistant to phenolic binder chemicals while providing gentle material handling.

Inlet Size Range

200mm to 450mm inlet flanges with enlarged offset entry zone accommodating the high-volume, low-density nature of expanded insulation materials.

Pressure Rating

Differential pressure sealing up to 0.5 bar with offset geometry that prevents trapping and crushing of fragile expanded insulation granules at the seal interface.

Temperature Range

Standard operation from ambient to 120°C, suitable for handling warm expanded perlite from furnace discharge and vermiculite from exfoliation ovens.

Blade Configuration

6-blade offset rotor with chamfered edges and UHMWPE blade tips, providing enlarged pocket clearance for zero-crush transfer of fragile insulation granules.

Industrial Applications

Expanded Perlite Gentle Feed
Feeds expanded perlite granules from furnace discharge into packaging and blending lines without crushing, preserving the cellular structure critical for insulation performance.
Vermiculite Granule Metering
Meters exfoliated vermiculite granules into batching and conveying systems without particle degradation, maintaining the expanded layered structure for thermal insulation value.
Lightweight Aggregate Transfer
Transfers lightweight insulation aggregates like expanded clay and foamed glass into mixing and forming lines with minimal particle breakage and dust generation.
