Name one type of valve commonly used in plumbing systems.

In plumbing systems, each type of valve serves a specific function and can be used in various applications, making all of them commonly utilized.

Gate valves are often used for on/off control in pipelines because they provide minimal resistance to fluid flow when fully open, making them ideal for situations where the valve is rarely adjusted. Ball valves are favored for their quick and reliable operation, as they can completely stop or start flow with a simple turn of the handle. They are well-suited for applications requiring frequent operation. Check valves play a crucial role in preventing backflow, ensuring that fluids only flow in one direction, which is important for maintaining system integrity and safety.

Since each of these valves offers distinct advantages and is a standard component in plumbing systems, the correct response encompasses all of them, highlighting the variety of valves that can be applied in different scenarios within plumbing configurations.
