What Is Globe Valve Vs Ball Valve？
Globe Valve Vs Ball Valve refers to two distinct types of valves used in fluid control systems.
A globe valve regulates flow through a system with a plug (often referred to as a disc or a ball) that moves perpendicular to the flow path. In contrast, a ball valve controls flow with a spherical disc (the ball) that pivots perpendicular to the direction of flow.
While both valves serve similar functions, their designs and mechanisms differ, leading to variations in their applications and performance characteristics.
How Does Globe Valve Vs Ball Valve work?
Globe Valve operates by using a plug (disc) that moves perpendicular to the flow path, regulating flow rates. Ball Valve utilizes a spherical disc (the ball) that rotates perpendicular to the flow direction, controlling fluid flow by opening or closing the passage. Both valves offer efficient flow control, but their mechanisms differ, leading to variations in performance and applications.

The Operation Theory of Globe Valve Vs Ball Valve
- Globe Valve Operation:
- Globe Valve Valves: The flow of fluid is regulated by a plug or disc that moves perpendicular to the flow path, controlling the flow rates. When the valve is closed, the plug tightly seals against the valve seat, preventing fluid from passing through. When opened, the plug moves away from the seat, allowing fluid to flow through the valve.
- Ball Valve Operation:
- Ball Valve Open or Closed: Ball valves operate by using a spherical disc (the ball) that rotates perpendicular to the flow direction. When the valve is closed, the ball is positioned perpendicular to the flow path, blocking fluid flow. Conversely, when the valve is open, the ball rotates 90 degrees, aligning with the flow path and allowing fluid to pass through the valve.
