IND-PTV - Globe Valves

Globe valves are primarily used for precise throttling applications, experiencing a greater pressure drop due to a 90-degree turn in the flow path. They consist of moving parts like the disk, valve stem, and handwheel. The fluid flow direction changes multiple times, increasing pressure drop. Typically, globe valves are installed with the stem vertical. Various disc types, such as plug, ball, composition, and needle, serve different purposes, from throttling to on-off applications.

What is the primary use of globe valves in industrial applications?

• On-off applications

• Precise throttling applications

• Temperature control

• Pressure relief

Which component of a globe valve connects the handwheel to the disk?

• Valve body

• Valve bonnet

• Valve seat

• Valve stem

How does the direction of fluid flow affect the pressure drop in a globe valve?

• It decreases the pressure drop

• It increases the pressure drop

• It has no effect on pressure drop

• It stabilizes the pressure drop

Which type of disc design is best suited for minimal throttling applications?

• Ball type

• Needle type

• Composition type

• Plug type

What is a characteristic of the composition disc type in globe valves?

• It is non-replaceable

• It is used for high-pressure applications

• It is replaceable and can handle various flow rates

• It is only used for low-temperature applications
