Rubber Lined Type Knife Gate Valve

Knife gate valves have a sharp cutting edge designed to handle viscous, heavy liquids or other abrasive media. Their straightforward design and easy-to-operate valve setup make them ideal for Mining, Iron and Stell Industry, Coal-fired power plants and power station Ash removal. With dedicated workshops and superior mold casting capabilities, LIXIN is sure to meet your knife gate valve needs.

 

KEY FEATURES:

  • Two-piece valve body.
  • Standard Wafer Design.
  • Integral ultra-thin body structure.
  • Vulcanized wear-resistant rubber.
  • Ultra-thin, compact, and lightweight design with an attractive appearance.
  • Easy installation and operation.
  • Clip-on connection and short face-to-face length reduce the overall weight of the pipeline system.
  • Smooth, groove-free gate bottom prevents impurity accumulation.
  • U-shaped sealing strip embedded in the valve body prevents leakage due to strip movement.
  • Enables two-way zero-leakage sealing.
  • Side-sealing structure achieves two-way sealing on three sides of the valve plate using sealing strips embedded in the valve body.
  • Sealing surfaces remain smooth and flush with the valve body.
  • Semi-circular valve plate bottom provides a full-bore flow channel when open.
  • No valve cavity design prevents medium accumulation.
  • Flow channel and sealing surface made of vulcanized wear-resistant rubber for superior wear and erosion resistance.
