Gate valves are crucial components in various industrial applications, primarily used for on/off control of fluid flow in pipelines. They are designed to provide minimal flow resistance when fully opened and a tight seal when closed, making them ideal for situations where the complete shutoff of flow is needed. One of the key aspects of gate valve performance is pressure — specifically, the pressure ratings and their implications for system design and operation.
