Valves and Their Classification

 Valves and it's Classification ‼️✅





Valves are devices that control the flow of fluids (liquids, gases, or slurries) in a system. Here's a classification of valves:


Types of Valves

1. *Gate Valves*: Used for on/off control, typically fully open or fully closed.

2. *Globe Valves*: Used for regulating flow, can be used for throttling.

3. *Ball Valves*: Quarter-turn valves used for on/off control.

4. *Butterfly Valves*: Used for regulating flow, often in large pipe sizes.

5. *Check Valves*: Allow flow in one direction, prevent backflow.

6. *Needle Valves*: Used for precise flow control.

7. *Relief Valves*: Designed to release pressure in a system.


Classification by Function

1. *Isolation Valves*: Used to isolate sections of a system.

2. *Regulation Valves*: Used to regulate flow or pressure.

3. *Safety Valves*: Designed to protect systems from overpressure.


Classification by Operation

1. *Manual Valves*: Operated by hand (e.g., handwheel, lever).

2. *Actuated Valves*: Operated by an external power source (e.g., electric, pneumatic).
