Stafsjö’s WB14 knife gate valve offers superior flow characteristics and bi-directional zero leakage shut-off. It is suitable for fluids such as water, sludge and bio mass. Integrated flange gaskets simplify installation works and the fully lugged body makes it also suitable for dead-end services.
The WB14 valve is modular designed and it can easily be customized in materials, with actuators and related automation accessories to different process conditions. It is supplied with a robust one piece and fully lugged valve body in nodular iron up to DN 300 (12″) and from DN 350 (14″) it features a rigid two piece version.
