Knife Gate Valves FL500
Our FL500 is a double plate knife gate valve for highest demands and particularly suits liquids with high solids content. This bidirectional sealing knife gate valve is primarily used in bulk and paper industry, especially for strongly contaminated and abrasive mediums. In opened position, both slide plates are inside the body and so ensure full bore. When closing, the slide plates push all contaminations out of the body into the flow. This design guarantees long service times at minimal effort. The different sizes, pressure stages, materials and drives are shown on the datasheet, which you can download on our website. For special executions please contact our sales department.
