Knife gate valves Series 300

The 300 Series Knife gate valves are ideal for applications handling highly viscous liquids, mud, thick slurry media and large solids. The hallmark of the 300 Series is a knife that runs the entire length of the body. The design prevents the build-up of dirt in the sealing element area, while the movement of the cap itself cleans the seat area very effectively and keeps the sealing elements in good condition in the long term.
