What is a ball valve used for?
Explanation
A ball valve is a shut-off valve that controls water flow with a simple quarter-turn handle. Inside the valve is a hollow ball with a hole through it—when the handle is aligned with the pipe, water flows; when turned 90 degrees, it blocks flow completely. Ball valves are reliable, durable, and commonly used as main shut-off valves and isolation valves throughout plumbing systems.
