Gate valves are an essential component of many systems that require isolation of fluid flow. Despite their usefulness, they are not designed to regulate or control flow, as their primary purpose is to either allow or interrupt the flow entirely. By turning the stem, the gate inside the valve can move up or down, thus opening or closing the valve. This design is particularly useful in situations where minimum pressure loss is critical, as there is very little to interrupt the flow when fully open.
Gate valves come in various configurations to suit different applications, including domestic, commercial, industrial, and irrigation systems. The valves can be equipped with handles or lockshields for added security, ensuring that only authorized personnel can operate the valve.
