Valve Working Principle
The globe valve operates through a linear-motion mechanism.
Opening
- The handwheel rotates.
- The stem moves upward.
- The disc lifts from the seat.
- Flow gradually increases.
Closing
- The stem moves downward.
- The disc contacts the seat.
- Flow is reduced and ultimately stopped.
- Tight shutoff is achieved.
This design provides precise control over flow rates and pressure conditions.
Quality Assurance & Testing
Each valve undergoes comprehensive testing before shipment.
