Gate Valve
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 Shut-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 minimum resistance to circulation
- For minimal amounts of fluid or liquid trapped in the pipe
- INTERNATIONAL DESIGN STANDARDS
- MAINTENANCE AND SERVICEABILITY
- INSPECTION AND TEST
- WELDED OR THREADED ENDS
- FACE TO FACE AND END TO END
- DESIGN AND MANUFACTURE
- INSPECTION AND TEST
At SMI we comply with all international design standards.
