Stop Material Flow Problems Before They Stop Your Production

Are you struggling with inconsistent feeding, dust leakage, or frequent jams in your pneumatic conveying system? Every downtime minute costs you. Headpowder's rotary feeder and rotary valve are engineered with precision tolerances and wear-resistant materials to deliver dependable, leak-free performance—keeping your bulk solids moving smoothly, cycle after cycle.

Reliable Rotary Valve for Demanding Bulk Material Handling

The headpowder rotary feeder (also known as a rotary airlock valve) is designed for the continuous metering and sealing of powders, granules, and pellets in pneumatic conveying systems. Built with a compact, robust housing and a precision-machined rotor, this valve minimizes air leakage while providing consistent flow control. It is a custom-engineered solution that adapts to your specific material characteristics, conveying pressure, and installation footprint.

Key Product Features

• Custom rotor designs (closed-end, open-end, adjustable tip, tapered) to suit abrasive, sticky, or fragile materials.
• Wear-resistant hard chrome coating, carbide-tipped seals, or stainless steel construction for extended service life.
• Low air leakage rate thanks to close-clearance rotor-to-housing fit and optional purge gas connections.
• Multiple drive options: direct drive, chain drive, or gear motor with variable speed control for precise flow rate adjustment.
• Hygienic and sanitary configurations with easy-clean features, suitable for food, pharmaceutical, and pet food applications.
• Explosion-proof, ATEX-rated designs available for hazardous dust environments.

Your Valve, Your Specifications – Custom Engineered

Every headpowder rotary feeder is built to order. We do not sell off-the-shelf stock units because no two material handling challenges are the same. After you provide details about your material (bulk density, particle size, abrasiveness, temperature), conveying pressure, and required throughput, our engineers will design the proper valve geometry, shaft sealing, housing material, and coatings. Contact us for a custom quote based on your exact application.
