Difference in one table
| Type | What it does | What it does not |
|---|---|---|
| Ball / shut-off | Closes/opens the line | Does not regulate pressure “to 3 bar” |
| Pressure-reducing | Lowers pressure to a setting | Is not a “normal tap” |
| Check valve | Blocks backflow | Is not a pressure reducer |
| Strainer | Catches particles | Is not a valve for looks |
