Bidirectional Knife Gate Valve – Serie GD


Slurry Valves

Slurry valve for very loaded products with solids, used for suspended matter in mining. It does not present neither salient nor any split in the pipe. It is not needed any joint between the flanges as it is incorporated in the body.

  • 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.

This valve main characteristic is that it provides a full continuous flow.

The GD valve’s body is composed of one single “monoblock” piece.


Standard manufacturing sizes:
From DN50 up to DN600

Bigger diameters under request.


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

Bidirectional Knife Gate Valve – Serie GD


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

Designed for the following applications: 

  • Thermal power stations
  • Energy Sector
  • Chemical plants
  • Mining
  • Sewage treatment


  • 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
