Knife Gate Slurry Valves - Serie GL

Knife Gate Slurry Valves – Serie GL

This valve´s main characteristics is that it provides a full continuos flow.
This means that in open position it produces no cavities and there are no turbulences in the fluid.

  • Bidirectional wafer‐design knife gate valve.
  • Monoblock one piece cast iron body.
  • Stainless steel gate. Two rubber sleeves.
  • Provides high flow rates with low pressure drop.
  • Various seat materials available.


– DN50 a DN1400
– (bigger sizes under request).


DN 50-600 = 10 bar
DN 700-900 = 6 bar
DN 1000-1400 = 4 bar


This knife gate slurry valves are suitable for working in the mining industry, in loaded  fluid  transport lines, such as: water with stones, sludge, and  in  general  it  is  used  for  abrasive  fluids  in  the  chemical  industry and waste water.

Designed for the following applications:
‐ Mining               ‐ Electrical power stations
‐ Sewage treatment ‐ Energy Sector     
‐ Chemical plants       ‐ Thermal power stations


  • Pressure Equipment Directive: (PED) ART 4.3 /CAT.1.
    • Potential Explosive Atmospheres Directive: (ATEX) CAT.3 ZONA 2 y 22 GD.


All valves are tested hydrostatically at CMO Valves, and material and test certificates can be provided.

  • Body test = working pressure x 1,5
  • Seat test = working pressure x 1,1
