Problem this solves
Ball valves excel at quick shutoff, while gate valves suit isolation. Use this comparison to avoid mis-specifying duty.
Ball vs gate valve comparison
| Factor | Ball valve | Gate valve |
|---|---|---|
| Operation | Quarter-turn | Multi-turn |
| Shutoff | Excellent | Excellent |
| Throttling | Not ideal | Not ideal |
| Pressure drop | Low | Low when fully open |
| Maintenance | Seat replacement | Stem/packing checks |
When to choose each
- 1Choose ball valves for quick shutoff and frequent operation.
- 2Choose gate valves for infrequent isolation in large lines.
- 3Avoid both for throttling; consider globe valves.
