As shown in the picture, there are pneumatic valves inside the tower. Considering the need for maintenance, it is definitely better to install a root hand valve. However, there are too many hand valves for each valve, and it will cause trouble for piping. How did you deal with this situation?
The regulating valve is generally equipped with a valve group, and the maintenance channels between the pipelines must be kept.
It is not practical to install a valve group. The entire facade of the tower is covered with valves. If a valve group is installed, the valves cannot be piped at all, and the upper and lower spacing between the valves is not allowed.
In our case, the entrance is cut off and the exit is not set up. Just make sure it can be cut off.
