Stafsjö’s knife gate valve MV is used within many different fields of applications. The valve has a gate with a bevelled edge that effectively cuts through different media. In a 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.
Stafsjö’s retainer ring system offers great flexibility and several seat material options. Up to DN 800, the MV has a one-piece valve body and from DN 900 it features a rigid two-piece version. Stafsjö’s gland box system with TwinPack braids ensures that no media reaches the surrounding environment. It can also be reinforced with a box bottom scraper or with a double gland for the most demanding applications.
Stafsjö’s knife gate valve MV can be used within a wide range of applications on both dry and wet media such as pulp stock up to 7% concentrations, sludge, slurry, biomass, water, ash, granulate and different kinds of waste.
