If a valve handle is at a 45-degree angle, what is the valve's position?

Explanation:
The handle angle shows how much the valve is allowing flow. When the handle runs in line with the pipe, the valve is fully open; when it sits at a right angle to the pipe, it’s fully closed. A 45-degree angle sits halfway between those extremes, which is described as cracked open. That means only a small amount of flow is allowed, suitable for a light or controlled opening. So at 45 degrees, the valve isn’t fully open or closed, it’s in a small-opening position.
