V860 Series
High Performance Rising Stem Top Entry Ball Valves
Key Features & Benefits
Basic Design Standard : ASME B16.34
Tilt-and-Turn Operation Mechanism
- The ball tilts and rotates before contacting the seat, eliminating seal rubbing. This mechanism minimizes wear between the ball and the seat.
Mechanically Energized Seal
- The cam angle at the lower end of the stem ensures the core is tightly wedged against the seat, providing a positive shutoff.
Self-Cleaning
- By tilting the core away from the seat before rotation, a 360° flow around the core surface is created, removing any foreign material.
Low Operation Torque
- With seal rubbing eliminated, the valve rotates easily. The dual action with a special mechanism achieves low operation torque.
Enhanced Durability
- The core surface is made of hardened material, resistant to wear and corrosion, providing a long lifespan.
Top Entry Design
- Allows for in-line inspection and repair after system depressurizing, simplifying maintenance.
Dual Stem Guides
- Reinforced stem slots and robust guide pins regulate the stem’s lift-and-turn movement.
