Q941f electric fluorine lined flange ball valve PN10 ~ PN16 is composed of electric actuator and O-type fluorine lined ball valve. The inner cavity and ball core of the electric fluorine lined ball valve are lined with corrosion-resistant and aging resistant poly (perfluoroethylene) by high-pressure injection molding process, so it has reliable corrosion resistance and sealing performance. It is mainly used to adjust or cut off strong corrosive media such as acid and alkali in the production process.

1. Be careful in installation and construction, and do not hit the valve.
2. Before installation, the ball valve should be inspected to check the specification and model, and identify whether there is damage, especially for the valve stem. Also turn a few times to see if it is skewed, because during transportation, it is easy to bump the stem. Also remove the debris in the valve.
3. When lifting the ball valve, the rope should not be tied to the hand wheel or the valve stem to avoid damage to these parts, but should be tied to the valve body.
4. The pipeline connected to the ball valve must be cleaned. Compressed air can be used to blow away iron oxide chips, mud and sand, welding slag and other impurities. These debris, not only easy to scratch the sealing surface of the ball valve, in which large particles of debris (such as welding slag), but also block the small valve, so that its failure.
5. The position of valve handle rotation should be reserved during installation. 6. The ball valve cannot be used as throttling. 7. The ball valve with transmission mechanism shall be installed vertically.
