Valves seem small, but choosing the right one changes performance, safety, and reliability. Let’s break down 4 types used in fluid systems: check, ball, plug, and butterfly.

Check valve → lets flow go one way only (no backflow)
Ball valve → open/close with a hollow ball inside that rotates 90°
Plug valve → similar to ball, but uses a plug with a hollow core to align/block flow
Butterfly valve → rotates a disc in the flow path to regulate or isolate

👇 In the first comment: internal parts, pros/cons, and examples in real systems.

Which of these valves have you seen in real life (plumbing, car, machines)? Tell me below.
