Features of Gate Valve

-
Full Bore Design
The flow path is straight. Pressure loss is very low when fully open.
-
Tight Shut-off
The gate provides good sealing when fully closed.
-
Bidirectional Flow
Most gate valves can work in both flow directions.
-
Slow Operation
The valve opens and closes gradually, which reduces water hammer.
Common Types of Gate Valves
Rising stem gate valve
The stem moves up and down, showing valve position.
Non-rising stem gate valve
The stem rotates but does not move vertically.
Wedge gate valve
Uses a solid, flexible, or split wedge for sealing.
Parallel slide gate valve
Uses parallel discs for high-temperature service.
