It mainly depends on how high your pressure is. If the pressure is particularly high, go to the right side. Otherwise, the valve stem bears too much pressure. If the pressure is not high, go to the left side.

The high voltage side is on the left side of the picture. [First of all, the general stop valve enters from the bottom and exits from the top. Secondly, if you look at the picture and the high pressure is on the right side, the pressure will be transmitted to the valve body seal, and the seal will not be able to withstand it. 】
Brother, what you said makes sense, but it still feels a bit far-fetched. For example, when the valve is fully open, the pressure on both sides is basically equal, and the pressure is very high. The seal must withstand high pressure. How do you explain this? Also, do you think the newly added picture is pair A or pair B? Thanks
It is true that the valve body should have an arrow, I think B is right.
I feel that on the left side, the pressure on the left side is the highest when it is fully closed. As the degree of the valve increases, the pressure on the right side gradually increases, and reaches pressure balance when it is fully open.
When it's fully open, it's okay not to seal it, right? What about when it has just started and when it is about to end?
