Stop Valves, also called outlet or shut-off valves are used for piping and plumbing systems to cut off or halt the flow of water, gas or other liquid flowing through a pipe. Usually, a pipe system will have a main shut-off and other valves that are placed strategically before the water flows into a fixture, such as a toilet or a shower. These valves are placed to stop or control water flow during routine maintenance activity or in case of emergencies or repairs.
