When the handle of a wafer valve is in-line with the pipe, what is the status of the valve?

When the handle of a wafer valve is in-line with the pipe, it signifies that the valve is in the open position. This alignment allows fluid to flow freely through the valve and pipeline, facilitating the movement of water or other substances through the system. In many valve designs, such as ball valves or butterfly valves, the handle's position directly correlates to the valve's status. An in-line handle typically means that the disc or ball inside the valve is aligned with the flow path, which permits unrestricted passage.

If the handle were perpendicular to the pipe, it would indicate that the valve is closed, blocking the flow. A valve could be considered broken if it does not function as designed, such as when it gets stuck or fails to seal properly, but the position of the handle alone does not provide that information. A partially open status would suggest the handle is not fully aligned with the pipe, leading to restricted flow, which is not the case here when the handle is in-line. Thus, having the handle in line directly confirms that the valve is open and fully operational.
