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. Turn it a few times to see if it is skewed, because Zui is prone to bump the stem during transportation. 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.
