Electric control ball valves offer advantages such as simple wiring, compact structure, small size, light weight, low resistance, and stable, reliable operation. They 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. These valves are widely used in petroleum, chemical, metallurgical, light industrial, papermaking, power plant, and refrigeration sectors. The electric regulating ball valve is a crucial valve type with extensive applications in petrochemicals, long-distance pipelines, and related fields. Its closing element is a perforated sphere (or partial sphere) that rotates with the valve stem to open or close the valve. Achieving full closure or full opening with a 90° rotation, the ball valve offers a more compact size and lighter weight compared to gate valves or globe valves of equivalent specifications, facilitating pipeline installation.
