Hunan ball valve Cast steel flange ball valve Product selection Product quotation Technical support After-sales service

Q41F cast steel flange ball valve is mainly used to cut off or connect the medium. It can also be used for the regulation and control of fluid. 1. Fluid resistance is small. Ball valve is the smallest fluid resistance among all valves. Even a reduced diameter ball valve has a relatively small fluid resistance. 2. The switch is fast and convenient. As long as the valve rod is rotated by 90 °, the ball valve can be fully opened or closed, and it is easy to realize fast opening and closing. 3. Good sealing performance. Ball valve seat sealing ring is generally made of elastic materials such as polytetrafluoroethylene, which is easy to ensure sealing, and the sealing force of the ball valve increases with the increase of the medium pressure. 4. Reliable valve stem sealing. When the ball valve is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easy to be broken, and the sealing force of the valve stem reverse seal increases with the increase of the medium pressure. 5. The ball valve only opens and closes by 90 °, so it is easy to realize automatic control and long-distance control. The ball valve can be equipped with pneumatic device, electric device, hydraulic device, gas-liquid linkage device or electro-hydraulic linkage device. 6. The ball valve channel is smooth and smooth, it is not easy to deposit media, and the pipeline can pass through the ball.
