Q41F Manual Ball Valve - Product Description

Manual flange ball valves are mainly used to cut off or connect media, and can also be used for fluid regulation and control. Compared with other types of valves, ball valves have the following advantages:
1. The fluid resistance is small, and ball valves have the lowest fluid resistance among all valve types. Even for reduced diameter ball valves, their fluid resistance is quite small.
2. The switch is fast and convenient. As long as the valve stem rotates 90 °, the ball valve completes the fully open or fully closed action, making it easy to achieve rapid opening and closing.
3. Good sealing performance. The sealing ring of the ball valve seat 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 medium pressure.
4. The valve stem seal is reliable. When the ball valve is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easily damaged, and the sealing force of the valve stem reverse seal increases with the increase of medium pressure.
5. The opening and closing of the ball valve can only rotate 90 degrees, making it easy to achieve automation and remote control. The ball valve can be equipped with pneumatic, electric, hydraulic, pneumatic hydraulic or electro-hydraulic linkage devices.
6. The ball valve channel is flat and smooth, not easy to deposit media, and can be used for pipeline ball passing.
