1、 Overview of Electric Three way Ball Valve Products
The Q944F/PPL/H electric three-way ball valve from Shanghai Yuhu Company is composed of an intelligent angular stroke actuator and a three-way ball valve. It is a rotary cut-off and regulating valve. The electric three-way ball valve has the advantages of tight closure, compact structure, light weight, and easy maintenance. Electric three-way regulating ball valves are widely used in pipeline automation control of corrosive media such as gas, liquid, steam, and oil. The two seat sealed electric three-way ball valve has a compact structure, beautiful appearance, and good sealing performance. Electric three-way ball valve can switch the flow direction of the medium in the pipeline. It can also connect or close two perpendicular channels. The four seat sealed three-way ball valve has a beautiful appearance, compact and reasonable structure. Electric three-way ball valves can not only switch the flow direction of the medium, but also connect the three channels to each other. Currently, any channel can be closed to connect the other two channels, flexibly controlling the merging or splitting of the medium in the pipeline.

5、 Control mode of electric three-way ball valve
Electric three-way ball valves are divided into L-shaped and T-shaped, and the direction of medium flow is shown in the following figure. The L-type electric three-way ball valve is suitable for switching the flow direction of the medium, which can connect two perpendicular channels. The T-shaped electric three-way ball valve is suitable for dividing, merging or switching the flow direction of the medium. The T-shaped hole can connect three channels to each other or two of them. The electric three-way ball valve generally adopts a three seat structure, and can also adopt a four seat structure according to user requirements.
