Understanding Globe Valves

Definition and Function

Globe valves are designed to regulate the flow of liquids and gases through a pipeline. They achieve this by using a movable disc, or plug, that fits into a stationary ring seat. The design allows for precise control over the flow rate, making globe valves ideal for applications that require throttling and frequent operation.

Basic Components

Body: The main structure that houses the internal components.
Bonnet: The cover for the valve body, which houses the stem and provides access for maintenance.
Stem: Connects the actuator or handle to the disc, allowing for movement to open or close the valve.
Disc: The movable part that regulates flow by seating against the valve seat.
Seat: The stationary ring that the disc fits into to stop flow.
