### What is the difference between globe valve and butterfly valve?
#### Globe Valve:
1. **What is it?** .
A globe valve is a type of valve used to regulate the flow of fluid in a pipeline. It consists of a movable disk (or plug) which closes against the flow of fluid, controlling the rate of flow.
.
2. **Design and Functionality** .
Globe valves have a spherical body shape with a disk attached to a stem that moves up and down to regulate flow. They provide good throttling capabilities and are suitable for controlling flow in piping systems.
.
3. **Applications** .
Globe valves are commonly used in applications where flow rate regulation is required, such as in cooling systems, steam lines, and hydraulic systems.
#### Butterfly Valve:
1. **What is it?** .
A butterfly valve is a valve that controls the flow of fluid through a pipeline by rotating a disk to open or close the passageway.
.
2. **Design and Functionality** .
Butterfly valves have a thin, disk-shaped body with a central pivot point that allows the disk to rotate 90 degrees to control flow. They are lightweight and require less space compared to globe valves.
.
3. **Applications** .
Butterfly valves are often used in large pipelines where quick shutoff is needed, such as water treatment plants, HVAC systems, and large-scale industrial applications.
In summary, the main differences between globe valves and butterfly valves are their design and functionality. Globe valves have a spherical body with a disk that moves up and down to regulate flow, while butterfly valves have a disk-shaped body that rotates to control flow. Globe valves are better suited for throttling applications, while butterfly valves are ideal for quick shutoff in large pipeline systems.
