characteristics of the Gate
Gate valves can be used in many applications. They allow the fluid to flow in a fully open position and be restricted in the fully closed position, with minimal load losses. Not recommended for intermediate positions.
Gate valves are bidirectional and can be installed horizontally or vertically.
competitive advantages
- Tight Shutt-off
- High capacity
- Low cost
- Simple design & operation
- Low resistance to circulation
Recommended for
- Service with total opening or total closing, no strangulation
- For infrequent use
- For mínimum resistance to circulation
- For minimal ammounts of fluid or liquid trapped in the pipe
