Audited Supplier Ball valves are the most reliable and common type of valves used to regulate the flow of water. It involves a rotating sphere with a hole that is attached to a lever handle to operate the valve.
In the open position, the hole in the sphere is in line with the pipe, allowing the water to flow through it. When in a closed position, the hole in the sphere is perpendicular to the pipe, thus completely restricting the water flow. The lever handle also serves as an indicator of whether the valve is open or closed. When the lever is perpendicular to the pipe, the valve is closed.
