Working Principle
The globe valve controls flow through the vertical movement of a disc toward or away from the seat.
Opening
- Handwheel rotates the stem.
- Disc lifts from the seat.
- Flow passage opens gradually.
- Flow can be accurately regulated.
Closing
- Stem lowers the disc.
- Disc contacts the seat.
- Tight shutoff is achieved.
This design provides excellent throttling characteristics and dependable sealing.
