Ball Valves vs Globe Valves

Ball valves and globe valves are two common types of valves used in a variety of applications. Here are some key differences and similarities between them:

1. Design: Ball valves have a spherical disc inside the valve body that rotates to control the flow of fluid, whereas globe valves have a disc or wedge that moves up and down to regulate the flow.
2. Flow control: Ball valves and globe valves are typically used for on/off control or for controlling the flow in a pipeline, while globe valves are used for regulating the flow and controlling the pressure in a pipeline.
3. Pressure and temperature: Both ball valves can handle high pressure and temperature applications. Globe valves are well suited for shut off or isolation applications.
4. Maintenance: Ball valves require minimal maintenance as they have fewer moving parts, while globe valves require more maintenance due to their complex design and more moving parts.
5. Cost: Generally, ball valves are less expensive than globe valves, but this can vary depending on the specific design and materials used.

In summary, the choice between the two types of valves will depend on the specific requirements of the application.
