Globe valves

Globe valves are a common type of valve employed in numerous industrial and maritime applications, recognized for their excellent throttling capabilities and precise flow control. The design of a globe valve features a movable disc or plug that regulates fluid flow by interacting with a stationary seat inside the valve body. Fluid flow is controlled by adjusting the position of the disc, which can be raised or lowered using a handwheel or an actuator attached to a threaded stem. When the disc is fully raised, the valve is open, allowing fluid to pass through, while lowering the disc onto the seat results in a closed position, stopping fluid passage. One of the key advantages of globe valves is their ability to provide fine adjustments in flow rates, making them suitable for applications requiring accurate flow control, such as in pressure and temperature regulation systems. However, due to their inherent design, globe valves typically exhibit higher pressure drops compared to other valve types like gate and ball valves, which can lead to increased energy consumption in certain systems.
