Product Description

Knife Gate Valves are specialized valves designed to handle thick liquids, fibrous materials like pulp, or gases. They use a thin, blade-shaped gate to control the flow, moving perpendicular to the flow direction. When closed, the sealing surfaces create a wedge, enabling a secure shut-off for enhanced control in demanding applications.

Structure & Sealing Options

  • Valve Body: Cavity-free design where the gate slides within a side guide groove.
  • Bidirectional Sealing: O-shaped valve seat enables bidirectional sealing with rigid or elastic options.
  • Self-Sealing: Primarily seals with medium pressure.
  • Installation: Recommended for vertical pipeline setups.
