Bidirectional – Knife Gate Valve – Serie XB

Bidirectional knife gate valve for abrassive fluids with variousconcentrations
of solids with zero leakage to enviroment. It is not needed any joint between
flanges as it is incorporated in the body. 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.

Standard manufacturing sizes: From DN50 up to DN1400


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


This knife slyrry gate 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 applications such as:
