Description

Main Features

  • The special design of the body allows for easy passage of the fluid and makes it ideal for use as silo discharge valve.
  • The valve is normally installed in the reverse position (seat upstream OFF seat) in order to avoid problems like solid accumulation, seat wear, difficult closing…
  • Flushing holes (x4) integrated on the body as standard. These purge port allow internal cleaning of the valve and avoid solids trapping.
  • Directional arrow in the body showing correct mounting position.
