Ceramic Sealing Wafer 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 wastewater treatment plants, cement plants, and mining facilities. With dedicated workshops and superior mold casting capabilities, LIXIN is sure to meet your knife gate valve needs. 

 

KEY FEATURES:

  • One-piece valve body.
  • Standard wafer, lugged, and semi-lugged design.
  • Knife gate provides strong shearing force.
  • Integral ultra-thin body structure.
  • Compact face-to-face dimensions and a lightweight valve body reduce the need for additional pipe support.
  • Suitable for media containing hard particles, soft particles, or fibers.
  • Excellent wear resistance, corrosion resistance, thermal insulation, and low thermal expansion coefficient.
  • Constructed from high-strength ceramic structural material, offering wear and corrosion resistance two to four times greater than ferroalloy and Monel materials.
