Features and Benefits:

1. Easily in-line inspection and maintenance

2. Maintenance can be performed without removing the valve from the line

3. The independent ball and stem design, which minimizes the side thrust caused by pressure by the ball, increases the efficiency.

4. Less potential leakage risks than the side entry ball valves.
