Knife Gate Valve WB14

Stafsjö’s knife gate valve WB14 is bi-directional tight and can therefore be installed into a pipe system independent of pressure direction. A fully lugged valve body design and
integrated flange gaskets makes it easy to install and also allows end-of-pipe installations. WB14 has a full bore with no cavity which gives excellent flow characteristics and this makes it suitable for fluids, sludge and liquids with solids in suspensions such as water, sewage and bio mass.

The WB14 has a robust coated and fully lugged valve body in nodular iron. It is equipped with a gate in stainless steel, which has a polished edge in order to minimize friction and to lower required operation force. The valve is supplied with a sealing profile in Nitrile or EPDM and this is reinforced with a steel core. The gland box is equipped with Stafsjö’s box packing TwinPack™, to secure that no media reaches the surrounding environment. The valve is modular designed and it can easily be supplied with different types of actuators and accessories.
