SQ trunnion mounted top entry ball valves are produced according to API 6A, API 6D, ASME B16.34 and ISO 17292 standards. The valves can be offered with both soft , metal or composite seats that can be configured with single or double piston effect to provide an effective double block and bleed (DB&B) in both closed and, on request, in open position.

Easily in-line inspection and maintenance
Maintenance can be performed without removing the valve from the line
The independent ball and stem design, which minimizes the side thrust caused by pressure by the ball, increases the efficiency.
Less potential leakage risks than the side entry ball valves.
