Our electric three-way ball valves are composed of an angular motion series intelligent actuator and a three-way ball valve, and are a type of rotating cut-off and regulating valve. They offer advantages such as tight closure, compact structure, light weight, and easy maintenance. Electric three-way ball valves are widely used in the automation control of pipelines for corrosive media such as gases, liquids, steam, and oils. The two-seat sealed electric three-way ball valve features a compact structure, attractive appearance, and good sealing performance. These valves can switch the flow direction of the medium in the pipeline and can connect or close two perpendicular channels. The four-seat sealed three-way ball valve has an aesthetically pleasing design and a compact, reasonable structure. In addition to switching the medium flow direction, these ball valves can also connect the three channels together, or close any one channel while connecting the other two, allowing flexible control of the convergence or divergence of media in the pipeline. Hence, they are referred to as electric three-way directional ball valves.

Electrical Three-Way Ball Valve - Control Method
Electrical three-way ball valves are available in L and T configurations, with the medium flow direction as shown in the following image. The L-type electrical three-way ball valve is suitable for switching the medium flow direction, allowing for the connection of two perpendicular channels: The T-type electrical three-way ball valve is used for medium分流，合并or flow direction switching. The T-type orifice can connect the three channels or connect two of them. Electric three-way ball valves typically feature a three-valve seat structure, but can also be customized with a four-valve seat structure to meet customer requirements.
