MP KGV - Stafsjo Knife Gate Valves

Stafsjö Series - MP Knife Gate Valves

Stafsjö’s knife gate valve MP is a full bore and a bi-directional tight valve with a preferred pressure direction. The valve has a gate with a bevel edge that effectively cuts through different media. This special shut-off technique makes the MP suitable for both fluids and dry media such as pulp, sludge, biomass, powder and different kinds of waste.

MP is supplied with a valve body in stainless steel that has integrated purge ports as standard. Stafsjö’s retainer ring system on one side of the gate and special gate supports on the other side makes it tight in both pressure directions.

 The gate support and seat also has a scraping function when the valve is operated which assures, together with the gland box system with three layers of our TwinPack^TM and a box bottom scraper, that no media reaches surrounding environment. The top work consists of aluminium beams and stainless steel tie rods, which gives good corrosion resistance and a stable operation. There are several actuator types and accessories to choose from in Stafsjö’s standard collection – all easily exchangeable between each other.

The MP valve is designed, manufactured, inspected and tested according to the European Pressure Equipment Directive (PED 97/23/EC) category I and II module A1. The valve is therefore CE marked when it is applicable.
