Which type of valve has a smaller flow rate?

The globe valve is recognized for having a smaller flow rate compared to the other types of valves listed. This characteristic is primarily due to its design, which includes a spherical-shaped body that creates significant turbulence and resistance to flow. The flow path in a globe valve is more convoluted, which means that the fluid must navigate through a more complex route, leading to a reduction in flow rate.

Unlike gate valves that are designed for minimal flow resistance, globe valves excel in applications that require precise flow regulation, even though they are not optimal for maximizing flow rate. This makes globe valves particularly effective in throttling applications, where controlling the flow volume is essential. In contrast, other types of valves, such as ball and gate valves, are designed to allow for higher flow rates with less obstruction when fully open. Check valves also facilitate flow but in one direction only and are typically not used for throttling or flow control in the same way that a globe valve is.
