Drop-Through Rotary Airlock Valves for Insulation Manufacturing Plants

UGES drop-through rotary airlock valves provide gentle, consistent material feeding for mineral wool, glass fiber, and calcium silicate insulation production lines. Designed to handle lightweight, fibrous materials without bridging or compaction, they maintain steady flow in pneumatic conveying systems.

Drop-Through Rotary Airlock Valves Key Specifications

Rotor Design

Open-end drop-through rotor with 6 deep-pocket blades optimized for low-density fibrous insulation materials, preventing fiber compaction and ensuring complete gravity discharge.

Housing Material

Carbon steel housing with epoxy-coated internals to resist chemical attack from phenolic resin binders and formaldehyde off-gases in mineral wool production.

Inlet Size Range

200mm to 500mm oversized inlet flanges to accommodate the high-volume, low-density nature of fibrous insulation materials without bridging.

Pressure Rating

Differential pressure sealing up to 0.5 bar with flexible elastomer shaft seals, suitable for low-pressure pneumatic conveying in insulation manufacturing.

Temperature Range

Standard operation from ambient to 120°C, handling warm mineral wool trimmings from curing ovens and recycled fiber from edge-trim recovery systems.

Blade Configuration

6-blade rotor with chamfered leading edges to shear through fibrous material without wrapping, and replaceable UHMWPE blade tips for gentle handling.

Industrial Applications

Mineral Wool Trim Recycling
Feeds shredded edge trimmings and production scrap from mineral wool lines into pneumatic return conveyors for reprocessing without fiber damage.
Glass Fiber Batch Feeding
Meters chopped glass fiber strands from storage hoppers into blending and forming lines, providing consistent volumetric feed without fiber clumping.
Dust Collection Discharge
Evacuates captured insulation dust and micro-fibers from bag filter hoppers, sealing the dust collection system while preventing re-entrainment of particulate.
