Rising Stem Knife Gate Valve

Rising stem knife gate valves employ a rising stem design coupled with a sharp-edged gate to provide precise flow control and reliable shutoff in slurry and abrasive media applications. The rising stem mechanism allows for visual indication of the valve position, making it easier to monitor and control the flow process. Rising stem knife gate valves are frequently used in industries such as mining, wastewater treatment, and pulp and paper, where effective handling of slurries, solids, and fibrous materials is essential.
