The position of the handle indicates the direction of the opening through the ball,
IE. handle in line with pipe, valve is open, tangent to pipe, valve is closed.
To determine if a pool valve is open or closed, check the position of the valve handle. Typically, a valve handle that is aligned with the pipe indicates it is open, while a handle that is perpendicular to the pipe signifies it is closed. Additionally, you can observe the flow of water; if water is flowing through the system, the valve is likely open. In contrast, if there is no flow or pressure, the valve may be closed.
The sensors that tell the car when the door is opened or closed are garbage.
You can tell if the fuel shut-off valve is tripped by checking for a lack of fuel flow to the engine or appliance it serves. If the engine won't start or runs erratically, it may indicate that the valve is closed. Additionally, many fuel shut-off valves have a visual indicator or a distinct position (open/closed) that can be checked manually. Listening for a click or observing a change in the valve's position can also confirm if it has been tripped.
advantages of a globe valve * you get instant access to the supply: only a 90 degree turn to open fully * less maintenance is required to the valve as you won't have to re-seat it disadvantage of a globe valve * it is harder to finely adjust the flow of your substance compared to a gate valve: a gate valve requires many more turns to fully open and close than the single 90o "part-turn" required on a globe valve
You can tell a bad valve by doing a compression test.
because the leaver is closed and it it not open

no you cant
Modulating Valve ???? If you can tell me what system this valve would be in I can tell you the correct name for it and its location. example IPR valve in the high pressure oil system.

Nothing really, it can tell you if the ball has a soft outer layer or not.
Noisy valve train. Remove the valve cover and inspect the valve train.
