What are the differences in sealing requirements for stop valves with air as the medium and those with water as the medium?

For example, can the globe valve J41H-16C DN80 be used for transporting both water and gas? Could there be any issues with sealing?
There won’t be any problems, as long as the quality of the valves is guaranteed
The stop valve J41H-16C can be used for both water and gas.
The same goes for water and air; they don’t require high levels of sealing, so it’s no problem.
Since it is used for transporting water and gases, ball valves or butterfly valves are a better choice; they are cheaper and perform much better than gate valves.
Sure, it’s no problem to transport hydrated gases.
For transporting water or air, there are no special requirements for the sealing surfaces of globe valves. It is recommended to use a valve with a relatively small diameter; a ball valve would be better.
