The Soft Seated Knife Gate Valve from Controtek Global is an incredibly effective way to regulate the flow of viscous fluids, wastewater, and slurries in industrial processes. These valves, which have a sturdy soft seat made of rubber or elastomer, have excellent sealing qualities that enable a bubble-tight shut-off even in harsh conditions. By providing leak-free operation and decreased friction during actuation, the soft seat material guarantees that the valve will perform exceptionally well in low to medium pressure applications. These valves are designed for sectors like mining, chemical processing, wastewater treatment, and the pulp and paper industry that need dependable flow control and the capacity to handle solids-laden media.
