FEATURES AND BENEFITS:
- Increased efficiency enabled by independent ball and stem, which minimizes side thrust caused by pressure on the ball
- Improved safety assured by anti-static design that guarantees electrical continuity between all metallic components
- Simplified in-line inspection and maintenance made possible by top-entry design
- Compliance with the most severe pollution-control regulations owing to low-emission valves
- Used whenever it is required to perform maintenance activities without removing the valve from the line
- Less potential leakage paths than bolted bonnet side-entry valves
