BRAND: StafsjöCATEGORY: Knife Gate Valves

These Stafsjö WB Series knife gate valves are all bi-directional and can be installed into pipelines independent of pressure direction. They are full bore and provide excellent flow characteristics making them ideal for fluids, sludge and liquids with solids in suspensions such as water, sewage and bio mass.

The valves are supplied with coated valve bodies in nodular iron semi lugged (WB, WB11) or fully lugged (WB14). Integrated flange gaskets up to DN 600 make it easy to install the valves and the fully lugged version also allows end-of-pipe installations.

The WB Series also features the Stafsjö high strength top works up to DN 600 with stainless steel tie-rods encapsulated inside structural beams together with stainless steel gate guards on remote operated valves. This new standard product offers great excellent resistance and a precise gate alignment independent of valve position.
