Knife gate valve MV

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.

MV is modular designed and can easily be customized to specific process conditions. As standard it is supplied with a valve body in either stainless steel or epoxy coated nodular iron, but it can also be supplied in a range of high alloy materials such as Duplex, Hastelloy, SMO and Titanium.

The MV valve is available in size ranging from DN 50 up to DN 1600 (2” to 64”).

Futher information is available in the product data sheet.



Proven and reliable shut-off

The gate and valve body design, especially the bore, gives the valve its ability to securely and effectively shut-off almost any flow. Minimal friction makes the valve easy to operate.

Solid and flexible top works

Stainless steel tie rods and aluminium beams gives good corrosion resistance and a stable operation, which is a prerequisite for a first-rate sealing. Chang-ing from one actuator to another one can easily be performed on the site.

Excellent adaptability

MV can easily be customized to different  process conditions, e.g. in special materials such as Duplex, Hastelloy, SMO or Titanium. The retainer ring system offers flexibility and cost-efficient on-site maintenance.
