COMPETITIVE ADVANTAGES
Gate valves are bidirectional and can be installed horizontally or vertically.
DESIGN FEATURES
- Tight Shutt-off
- High capacity
- Low cost
- Simple design & operation
- Low resistance to circulation
Recommended for
- Full opening or full closing service, without throttling.
- For infrequent use.
- For minimum flow resistance.
- For minimum amounts of fluid or liquid trapped in the pipe.
