Which valve is least susceptible to wire drawing and seat erosion?

The globe valve is known for its design, which includes a spherical body and a diaphragm that controls flow. It operates by allowing fluid to pass through an opening and into a chamber and typically offers precise flow control. However, when it comes to susceptibility to wire drawing and seat erosion, it’s important to consider how different valves engage with the flow of fluid.

In contrast to the globe valve, the gate valve operates by lifting a gate out of the flow path, which can lead to wire drawing if there is high velocity and turbulence. The plug valve, while versatile, can also experience issues with erosion depending on the material and nature of the flow. The wedge gate valve, similar to the standard gate valve but with a wedge-shaped design for better sealing, can also suffer from these problems, especially when used in high-pressure applications.

The globe valve's design allows it to handle fluids in a more controlled manner, with a less aggressive flow pattern, which results in a lower risk of wire drawing and seat erosion compared to the other types mentioned. This makes it the most suitable choice in scenarios where these factors may be a concern. In addition, the globe valve's ability to effectively manage flow and maintain a more consistent pressure helps mitigate potential damage over time.
