Trunnion Mounted Flange Ball Valve, Carbon steel material, 150LB, with drain valve , is a high performance ball valve for long distance for pipeline, it is more safe and strength, it is suitable for various corrosive and non-corrosive medium. 

Trunnion mounted ball valve can bear high pressure, and torque is small, the sealing performance is stable, then valve service life is longer than floating ball valves. 

Trunnion Mounted Flange Ball Valve have two seats, bi-directional type seal. It is more safe to avoid leakage. Then there is no limit for installation. 

Trunnion Mounted Flange Ball Valve have fire safe design, conform to API6FA and API607 standard. It also has automatic pressure relief function by seat, not by safety valve, this is very important when valves delivery medium.

We can choose full port or reduce port to meet pipeline needs, it is more convenient for cleaning or other request.
