On horizontal pipes, will installing the valve stem in a downward position cause damage to the valve? The medium contains 400 g/L of solids; for such a medium and this type of installation, gate valves or globe valves, or valves designed specifically for liquefied gas, should be used. These valves basically require that they cannot be installed in an inverted position (with the valve stem pointing downward), as this does not meet the installation requirements. By looking at the specific structure of the valve, one can know.
The valve is a globe valve; no matter in which direction the flow occurs, the valve body should be filled with the medium, right? What if it is installed horizontally?
It is fine to install the stop valve horizontally, with flow from low to high. It is certain that the valve chamber is filled with liquid. Generally speaking, only the upward orientation of the valve stem is emphasized; horizontal orientations are less common but do exist as well. There are also many valves installed vertically.
