SQUARE MODEL

Unidirectional knife gate valve whose design depends on the customer’s specific needs. Ideal for installations handling fluids loaded with solids in suspension at low pressure. Recommended for use in silo outlets (mining, cement industries, petrochemical industry, etc.).

The main features of the valve:

  • Welded body design
  • Installation between flanges
  • Quadrangular or rectangular passage: enables a high flow capacity with low load loss.
  • Gate with rounded edges prolongs the working life of the rings and packing.
