Electric control ball valves offer advantages such as simple wiring, compact structure, small size, light weight, low resistance, and stable, reliable operation. These valves are typically used in applications requiring strict sealing. Beyond controlling gases, liquids, and steam media, they are also suitable for controlling sewage and media containing fibrous impurities. They are widely used in petroleum, chemical, metallurgical, light industrial, papermaking, power plant, and refrigeration sectors.
