Rotary Airlock Dust Duty Valve

The DDV Dust Duty Valves are designed to provide a low-cost airlock solution for simple dust collection under baghouses and cyclones, handling materials that are dry and mildly abrasive.

A Meyer rotary airlock feeder, the Dust Duty Valve design is uniquely suited for low-pressure applications where a quality air seal is necessary in light duty non-abrasive dust collection applications.

The DDV valves are available in sizes 6 through 14 with square or round housings to match most collector discharge flanges.
