API6D Ball Valves 2PC 3PC


Trunnion mounted Ball Valves 2PC/3PC in accordance with API6D is widely used in the opening and closing of natural gas pipelines and buried pipelines, and has the characteristics of safety and long service life.


1.Fire-proof and anti-static, the valve stem is anti-blow, automatic pressure relief, double block and double drain.

2.The fluid resistance is small. The ball valve has the smallest fluid resistance among all valves. Even the reduced diameter ball valve has relatively small fluid resistance.

3.The operation is fast and convenient. As long as the valve stem rotates 90°, the ball valve completes the fully open or fully closed action, and it is easy to open and close quickly.

4.Good sealing performance. Ball valve seat sealing rings are generally made of elastic materials such as teflon, PEEK, PPL, which are easy to ensure sealing, and the sealing force of the ball valve increases with the increase of medium pressure.

5. The valve stem is sealed reliably. The valve stem only rotates when the ball valve is opened and closed, so the packing seal of the valve stem is not easily damaged, and the sealing force of the reverse seal of the valve stem increases with the increase of the medium pressure.

6. The ball valve channel is flat and smooth, it is not easy to deposit media, and the pipeline can be ball-passed.
