Shut-off valves are commonly used in residential plumbing, whereas gate valves are primarily seen in commercial and industrial settings. Shut-off valves stop water flow in a straight line and are easy to operate. They have a small handle that you can turn to stop the water flow. Shut-off valves come in different materials, such as brass, chrome, and plastic, but the most common type is the quarter-turn ball valve. These valves are reliable and long lasting, making them a preferred choice among homeowners.
