New knife gate valve from Flowrox for heavy-duty applications

Flowrox has launched a brand new knife gate valve specifically designed for demanding and heavy industrial use.

The SKW design includes new features based on direct feedback from the field, including a new load distribution ring that prevents over compression during the installation and ensures 100% sealing between the ring sleeve and the valve gate. To add to ease of maintenance, the load distribution ring has been integrated into valve sleeves.

SKW allows bi-directional flow of the slurry due to its closing mechanism and the body of the valve is made as one casting, reducing the number of parts meaning there is no need for sealing between the body halves. The valve also features a universal tower design that allows any actuator to be easily connected to the tower structure. They can also be changed after the valve has been installed in the pipeline. The tower also ensures that the top plate, body and actuator are always aligned with the pipeline and the gate is in the right position.

The SKW valve is suitable for processes where the medium includes solids or abrasive substances.
