GLOBE VALVE

GLOBE VALVE USES

Globe valves are used to regulate the flow of a fluid and to shut-off the fluid (even if for shut-off operations ball valves and gate valves shall always be preferred). Globe valves are bi-directional valves, differently from check valves, meaning that the fluid can flow either way within the valve. The image illustrates how the valve works and its main components: basically, the flow is managed via a disc that can be lifted (manually or via actuators) from the seat, thus regulating the volume of the allowed flow.
