The three-way insulated ball valve generally adopts a two seat structure, as shown in the two operating conditions in flow diagram A. First, use two types of L-shaped valve seat structures (i.e. QB44 type). Two types of valve seat T-shaped structures (i.e. BQ45 type) can also be selected for the two operating conditions ① and ④ in flow diagram B. The two working conditions ② and ③ in flow diagram B must be designed with 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 "Model Compilation of Ball Valves" and fill in the corresponding code.
