Electric Three-Way Ball Valve Product Overview
Our company's electric three-way ball valve consists of an angular stroke series intelligent actuator and a three-way ball valve. It is a rotary type shut-off and regulating valve, featuring tight closure, compact structure, light weight, and easy maintenance. The electric three-way regulating ball valve is widely used in pipeline automation control for gases, liquids, steam, oil, and other corrosive media. The two-seat sealed electric three-way ball valve has a compact structure, attractive appearance, and excellent sealing performance. The electric three-way ball valve can switch the flow direction of the medium in the pipeline and also connect or close two mutually perpendicular channels. The four-seat sealed three-way ball valve has an aesthetically pleasing design and a compact, rational structure. The electric three-way ball valve not only enables switching of the medium flow direction but also allows the three channels to interconnect. It can also close any one channel while connecting the other two, providing flexible control for the confluence or diversion of the medium in the pipeline. Hence, it is referred to as an electric three-way directional ball valve.

Electric Three-Way Ball Valve Control Method
Electric three-way ball valves are divided into L-type and T-type. The medium flow directions are shown in the figure below. The L-type electric three-way ball valve is suitable for switching the flow direction of the medium and can connect two mutually perpendicular channels. The T-type electric three-way ball valve is suitable for the diversion, confluence, or switching of the medium flow. The T-type channel allows all three channels to interconnect or any two channels to connect. The electric three-way ball valve generally adopts a three-seat structure but can also be customized with a four-seat structure based on user requirements.
