The electric three-way ball valve is a switching-type regulating ball valve capable of diverting, splitting, or merging media flow through three pipelines. It typically features flanged or internal threaded connections. Depending on flow direction switching requirements, the ball core can be designed in L-type or T-type configurations to achieve various fluid control combinations within pipelines. The electric three-way ball valve not only switches or shuts off two mutually perpendicular channels but also closes any single channel while connecting the other two, flexibly controlling the convergence or divergence of media within the pipeline. By selecting actuators with different functionalities, it meets diverse operational requirements and is widely used in industrial systems such as power generation, environmental protection, water supply, steam systems, and mechanical equipment for two-position shut-off or proportional regulation.
