May I ask if the valve stem of the control valve can be vertical downward or at an angle downward? ? ? Why? ?
In principle, the valve stem should not point vertically downward; it can be angled 45 degrees downward, but pointing downward is not recommended for pipelines carrying toxic, harmful, or flammable substances. Since the valve stem is a static sealing point, there is a risk of material leakage, and it can easily cause injury when facing downward.
Heheh, young man, the conditions you’ve offered are limited. What kind of control valve is it? Pneumatic? Electric?

In principle, the valve stems of all valves (including gate valves and control valves) must not point vertically downward.
Why, if I remember correctly, Danfoss has a valve that requires to be oriented vertically downward?
Is it that difficult to open the valve on your steam pipeline?
