- Seats are self-adjusting, assuring leak-tight closure under all operating conditions and valve orientations.
- Automatic compensation for changes that occur as a result of varying pressure, temperature and wear.
- Sealing elements are kept in tight contact with the ball to assure an even load on the seats at all pressures, temperatures and at all stages.
- Ball is wiped clean each time the valve is operated
- Ball-seat contacts is constantly manteined, extending seat life
- Minimal number of components
- Top Entry configuration allows fast, easy, in-line service and permits emergency situations to be safety and quickly esolved
- All working parts are accessible for service
- No special tools or training required for maintenance and repair
