Which type of valve is commonly used to control the flow of water in plumbing systems?

The ball valve is widely recognized for controlling the flow of water in plumbing systems due to its design and functionality. It operates with a spherical disc, or "ball," that has a hole through the center, which allows for smooth flow when aligned with the pipe. This design enables quick opening and closing, providing excellent control over the water flow. Additionally, ball valves are durable and can maintain a tight seal, minimizing the risk of leaks, making them a reliable choice in various plumbing applications.

Their versatility is another significant advantage; ball valves can be used in various systems, including those requiring frequent on-off operation. The simplicity of their design contributes to their effectiveness, as they can effectively manage both low and high-pressure scenarios. This combination of traits makes ball valves a preferred option for controlling water flow in both residential and commercial plumbing settings.
