WB / WB 11Wafe Type Knife Gate valve for water applications

These valves are all bi-directional and can therefore be installed into pipe systems independent of pressure direction. Full bore and excellent flow characteristics makes them suitable for fluids, sludge and liquids with solids in suspensions such as water, sewage and bio mass.
