Premium-grade ductile iron knife gate valves from Controtek Global are designed for dependability, strength, and durability. These valves, which are made of ductile iron, are more durable and have a greater capacity to handle pressure than those made of regular cast iron. They are made specifically to easily handle difficult media like slurries, wastewater, pulp, powders, and abrasive materials. A tight shut-off is consistently provided by the sharp-edged gate, which guarantees a smooth cutting action through solid particles and thick fluids. The ductile iron knife gate valves from Controtek Global are a reliable option for a variety of industries, including chemical processing, pulp and paper, wastewater treatment, and mining, due to their exceptional corrosion resistance, long service life, and low maintenance needs.
