Overview

1. The two seat sealed three-way ball valve has a compact structure, beautiful appearance, and good sealing performance. It can switch the flow direction of the medium in the pipeline and also connect or close two perpendicular channels. (As shown in flow diagram A) 2. The four seat sealed three-way ball valve has a beautiful appearance and a compact and reasonable structure. It can not only switch the flow direction of the medium, but also connect the three channels to each other. At the same time, it can close any channel and connect the other two channels, flexibly controlling the merging and splitting of the medium in the pipeline.

remark

Three way ball valves generally adopt a double-sided valve seat structure, as shown in two working conditions in flow diagram A. Choose a two seat L-shaped structure (i.e. BQ44 type). The two working conditions ① and ④ in flow diagram B can also use a two seat T-shaped structure (i.e. BQ45 type). The two operating conditions ② and ③ in flow diagram B must use a four seat T-shaped structure (i.e. BQ45 type). The four seat structure can also be used for other working conditions, but the seat structure should be specified in the purchase contract. If there are other requirements for the valve, please refer to the sample "Method for Model Compilation of Ball Valves" and fill in the corresponding requirement code
