Types of Valves

Different types of valves serve various functions in industrial applications. Below is a comparison table that outlines the differences between common valve types.

Valve Type	Description	Advantages	Disadvantages
Gate Valve	Used for on/off control, allowing full flow when open.	Minimal pressure drop, low friction	Slow operation, not suitable for throttling
Globe Valve	Designed for regulating flow, with a spherical body.	Good throttling capability	Higher pressure drop, larger size
Check Valve	Prevents backflow in pipelines, allowing flow in one direction only.	Automatic operation, prevents damage	Limited to specific applications
Butterfly Valve	Uses a rotating disc to control flow, suitable for large volumes.	Lightweight, quick operation	Limited pressure rating
Ball Valve	Features a spherical disc to control flow, providing tight sealing.	Quick operation, low pressure drop	More expensive than other types
