- Model DDV - 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. This design is uniquely suited for a low pressure application 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.

  • Pressure Rating: 60″ WC
  • Maximum Operating Temperature: 350°F
  • Materials: Dry Free Flowing Mildly Abrasive

  • Our rotary airlock valves are used in a wide range of applications where there is need to minimize system air loss while transferring material between vessels with differing pressures.
  • They are used as feeder valves to meter the flow of material between vessels with equivalent pressures.
  • You will also find them doing double duty in systems where there is a need to minimize system air or gas loss while regulating the flow of material between vessels with differing pressures.

  • Dust Collection, Metering, Cyclone, Low Pressure, Separator, Conveying Systems
