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.
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.
