Which connection method is correct?

1 is correct. The valve is located near the main pipe, facilitating replacement
Personally, I think there’s no problem. The second photo isn’t clear enough; it needs to be searched for
Behind the right main pipe, it’s not easy to ensure the welding quality of the small pipes, right?
Both the installation methods in Figure 1 and Figure 2 are acceptable; it is recommended to add a gauge valve in Figure 1 to facilitate the replacement of the pressure gauge.
The manual valve is placed at the base of the main pipe; if the instrument buffering system or the instruments themselves fail, it is possible to shut off that section. If the valve is placed higher up, it will be difficult to carry out maintenance and shutdown operations
It is still better to use flanges; try to minimize the number of threaded connections, as they are prone to leaks
