Stafsjo MV Positive Shutoff Knife Gate Valve

Stafsjo‘s MV knife gate valve has a bevel-edge gate 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.

It comes standard with a stainless steel or ductile iron body, stainless steel gate, and EPDM seat. Like other Stafsjo valves, the MV comes with Stafsjo‘s box packing TwinPack™, to secure that no media reaches surrounding environment. The gland box can also be supplied with a box bottom scraper or with double gland for the most demanding applications. The top works consist of aluminum beams and stainless steel tie rods, providing good corrosion resistance and a stable operation.
