- High-Cycle, Live-Loaded Stem Packing
Dynamic loading on stem packing ensures a tight seal through varying pressure and temperature conditions, reducing maintenance costs and extending service life
- Full Port Design
Improves flow resulting in increased process efficienciesl
- 3-Piece Construction
Easy to repair
- Blow-Out-Proof Stem
Stem is bottom loaded to prevent removal when valve is in service
- Locking Device
Enables plant personnel to secure valve in open or closed position when manually operated
- Investment Cast
Improves dimensional control and reduces porosity
- Pressure Blance Hole in Ball Slot
- Anti-Static Device for Ball-Stem-Body
Blow-out Proof Stem
Pressure Balance Hole in Ball Slot
Lock device
