Knife Gate Valves FB700

Our knife gate valve FB700 is the latest innovation in our large range of knife gate valves. The special feature of this knife gate valve is the plain body without any dead space in combination with a bi-directional sealing. So it’s not possible that solids will build up inside the valves body and may jam the valve. On the other side our FB700 knife gate valve is tight in both directions up to the nominal pressure. This bi-directional knife gate valve is excellent for pipelines whose direction of flow, respective pressure direction, may change.

The brilliant and simple construction of body and our new U-profile seat guarantee a long, failure-free operation at a minimum amount of maintenance. The applications of the FB700 knife gate valve are paper and pulp industry, power plant technology, water and sewage technology, chemical industry, food industry, bulk industry and many more. The different sizes, pressure stages, materials and drives are shown in the column on the right. For special executions please contact our sales department.
