3.Full bore butterfly valve is classified according to the connection method:

1)The flange type Full bore butterfly valve is a vertical plate structure. There are two integrally cast flanges on both sides of the butterfly valve, which are directly connected to the pipeline flange. They are manufactured by the same standard. Such a butterfly valve is also called a double flange. Butterfly valve

2)The wafer type Full bore butterfly valve is installed in the diameter direction of the pipe, and the valve is fully open. The four holes on the valve body are used for positioning, and the processing standards for the four holes are the same as the pipe flange standards. Use two flanges on the pipe to clamp the butterfly plate and fix it with bolts. , Wafer type Full bore butterfly valve has simple structure, small size and light weight, so it is the most widely applicable and most sold connection method.

3)The lug type Full bore butterfly valve is based on the wafer type Full bore butterfly valve, which completes the pressure holes on all flanges. The installation method is similar to the wafer butterfly valve.

4)Butt-welding type Full bore butterfly valve is that both the pipe and the butterfly valve are processed with a groove, and the groove can be completed by electric welding. After cooling, the butterfly valve is completely welded to the pipeline. Such a butterfly valve requires great quality requirements. If an accident occurs, the butterfly valve needs to be disassembled, and the valve needs to be cut off as a whole, and the maintenance cost is very high.
