Fly Ash Intakes


Fly Ash Diffuser Feeders (FAD’s) are a swing style valve designed to provide positive shutoff and consistent ash flow in both vacuum and pressure conveying applications. The diffuser stone on the inlet side of the valve maintains ash stored above the valve in a fluidized state for consistent, high flow discharge when the valve is opened. This quality of discharge allows for ideal feeding of ash into the pneumatic conveying system to maximize the system capacity and reliability.

Features & Benefits

  • A durable, high quality stone diffuser provides consistent fluidizing of the material entering the valve or stored above the inlet.
  • A sharp-edged seat, swing style valve provides positive leak-free shutoff of material flow for a variety of ash types. The sharp seat prevents material buildup on the sealing surface that could prevent positive closure. The UCC Pivot Ball disc design accommodates different materials, operating conditions and maintenance techniques to allow the valve to self-correct disc to seat misalignment and prevent leakage.
  • Standard high chrome DURITE® H and optional Tungsten Carbide seat and disc provide for long, trouble free valve wear life
