What is a benefit of using a globe valve?

1. Valves can easily be replaced

2. Valves are not affected by throttling

3. Valves have a compact design

4. Valves provide automatic closure

The correct answer is: Valves are not affected by throttling

The benefit of using a globe valve primarily lies in its ability to handle throttling effectively. Globe valves are specifically designed for flow regulation, allowing for precise control of the volume of fluid passing through them. This capability makes them ideal for applications where consistent flow control is required. While some valve types might struggle with throttling, globe valves can maintain a more stable flow rate, which is essential in many industrial and residential applications. The design of the globe valve features a spherical body with an internal baffle that helps in achieving this precise control. The flow path is more convoluted compared to other valve types, which contributes to its effectiveness in throttling applications. Understanding the significance of throttling control provided by globe valves helps in selecting the appropriate valve type for specific scenarios, especially when regulating flow is crucial for system performance.
