The Motorized Knife Gate Valves from Controtek Global combine the accuracy and convenience of electric motor-driven actuation with the reliable performance of conventional knife gate valves. These valves, which are made for industries that need automated flow control in challenging conditions, provide dependable performance even when working with thick slurries, abrasive fluids, and media that is heavy in solids. By enabling smooth remote operation and precise control over valve opening and closing without the need for manual intervention, the motorized actuator improves operational efficiency and safety. The motorized knife gate valves from Controtek Global are made of premium materials like carbon steel or stainless steel and are designed to endure high pressures and temperatures, offering corrosion resistance and long-lasting durability.
