Universally Applicable Knife Gate Valve

Stafsjö’s knife gate valve MV is used within many different fields of applications. The valve has a gate with a bevel edge that effectively cuts through different media. In closed position the gate is pushed onto the seat which gives a tight and reliable sealing. This special shut-off technique makes the MV valve suitable for both fluids and dry media such as pulp, sludge, biomass, powder and different kinds of waste.
