Meyer Industrial HDX Direct Drive
The HDX Direct Drive Rotary Airlock Valve from Meyer Industrial is engineered for efficient and reliable dry bulk material handling in demanding industrial systems. Designed for applications where ease of installation, reduced maintenance, and improved mechanical efficiency are priorities, the direct drive configuration eliminates conventional sprocket and chain drive components while delivering consistent performance in pneumatic conveying, dust collection, and bulk flow control.
Clean and Efficient Design
-
Direct drive is mounted on the valve shaft for a compact, streamlined design that reduces mechanical complexity.
-
Approximately 10% more efficient than conventional worm-reducer and chain drive rotary valves, lowering energy loss and improving throughput.
-
No sprockets, chains, or chain guards are needed, which simplifies installation, improves safety, and lowers maintenance requirements.
-
Easily adjustable speed when paired with a variable speed controller for precise material flow control.
-
HDX Direct Drive can be designed to be compliant with NFPA 68 and NFPA 69 safety standards.
-
Speeds range from 9-29 RPM
- XP Motor can be used with HDX Direct Drive
