It is important in plumbing because it controls the water supply and drainage from a specific area. The most commonly used valves are:Ball Valve ? has a rotating ball that has a hole drilled through the center, when the hole is perpendicular to the flow of water through the pipe, the valve closes. You can limit the flow of water by twisting the lever so it will partially close.Gate Valve ? uses a gate to allow or stop fluid from flowing through a pipe. It should be completely open or closed else the water that flows through can wear away the metal. It is commonly used for outdoor taps. Check Valve ? ensures that water flow in one direction. It allows you to choose to stop the fluid in the backward direction or both.Stop valve ? used to shut off sinks or toilets. It is closed by screwing a rubber gasket in the middle. Align the valve with the flow of direction of the fluid, else the fluid will force the gasket away from the top of the valve.
