KNIFE GATE VALVES

T400 – SILO TYPE

The model 400 knife gate valve is a unidirectional wafer monoblock valve designed for industrial general service. Mainly used in bulk handling applications, discharge of powders and solids as OFF seat position (prevent solid accumulation in the seat area). Low pressure duty in solid discharge lines.

Applications: Pulp and Paper, Power generation, Water and Waste Water, Powder and Bulk Handling, Mining, Chemical, Food and Beverage.

  • 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.
