Product Overview
Gas pipeline flange ball valves are mainly used to connect or block the medium in the pipeline, especially in areas that require rapid opening and closing, such as emergency unloading. Due to its advantages such as simple structure, few parts, light weight and good sealing performance, it is increasingly widely used. It is mainly composed of the valve body, valve cover, sealing valve seat, ball and valve stem, etc. The ball with holes is the core of the ball valve. The ball is controlled to open and close by the rotation of the valve stem, and the rotation is the full process of opening and closing.
Structural characteristics
The gas pipeline flange ball valve adopts formed polytetrafluoroethylene packing and is suitable for most high and medium pressure gas transmission occasions. The handle operation torque is stable, and the O-ring is used to prevent external impurities from entering the valve interior. And maintain the long-term sealing performance of the valve. Ball valves larger than DN150 are driven by worm gears.
