I think it’s possible; why not? Ball valves have direction requirements

Will vertical installation of a large-diameter ball valve require high specifications for the cylinder? 2. Is it appropriate to use ball valves for steam?

Yes, for the installation of pneumatic ball valves, they can be installed at a 90-degree angle or horizontally at a 180-degree angle; since ball valves open at a 90-degree angle, both installation methods can be used, depending on the space available at the installation site.

They can all rotate 90 degrees; the difference is that the plug body is spherical, with a circular hole or passage running through its axis. That is, when the sphere rotates 90 degrees, its surface should be fully visible at the inlet and outlet, thereby interrupting the flow. Therefore, the valve can be installed at any position in the pipeline. But it is better to install it horizontally
