Working Principle
The globe valve controls flow through the vertical movement of the disc.
Opening
- Rotating the handwheel raises the stem.
- The disc moves away from the seat.
- Flow passage opens progressively.
- Flow rate can be precisely adjusted.
Closing
- Turning the handwheel lowers the stem.
- The disc contacts the seat.
- Tight shutoff is achieved.
- Reverse leakage is minimized.
