“A stop valve, also known as a shut-off valve or isolation valve, is a type of valve used to control the flow of fluid (liquids or gases) in a pipeline or system. Its primary purpose is to start or stop the flow completely, as opposed to regulating the flow rate. Stop valves are commonly found in plumbing systems, industrial processes, and various applications where the on/off control of fluids is essential.
Stop valves typically have a hand-operated lever or wheel that can be turned to open or close the valve. When the valve is open, it allows fluid to flow freely through the pipeline. When the valve is closed, it blocks the flow, preventing any further passage of the fluid.
Stop valves come in various types and designs, including ball valves, gate valves, globe valves, butterfly valves, and more, each suitable for specific applications and requirements. They play a crucial role in maintaining the safety and control of fluid systems by allowing maintenance, repair, or isolation of certain sections of the pipeline when needed.”
