Carbon Steel Knife Gate Valves from Controtek Global are strong and effective, made for demanding industrial applications. These valves are made of sturdy carbon steel and offer exceptional strength, dependability, and wear resistance, which makes them appropriate for handling corrosive media, powders, viscous fluids, and abrasive slurries. Smooth cutting through solid or thick fluids is ensured by the sharp-edged gate, and a tight shut-off with little leakage is guaranteed by the precision design. Carbon steel construction is perfect for heavy-duty applications in power plants, mining, steel manufacturing, chemical industries, and wastewater treatment because it has a higher pressure and temperature handling capacity than cast iron or ductile iron valves.
