1. The ball valve with FEP lining layer has high chemical stability, It can be applied to any strong corrosion property except for "molten alkali metal and element fluorine";

2. With full bore and floating ball structure, the valve can be closed without leakage in the whole pressure range, which is more convenient for ball cleaning and pipeline maintenance of pipeline system

3. The ball part of the opening and closing part and the valve rod are cast (forged) as a whole, which eliminates the possibility that the valve stem can be pushed out of the pressure bearing parts due to the pressure change, and fundamentally ensures the safety of the use in the project;

4. The structure is compact and reasonable, and the inner cavity space of the valve body is small, which reduces the medium retention. In addition, the special molding technology makes the sealing surface have good density, and the herringbone ring PTFE packing combination makes the valve achieve zero leakage; 5. The two-piece and three-piece structure can adapt to various pipeline systems and working conditions with different requirements. The three-piece ball valve allows the main valve body to be separated from the two-sided valve bodies, which can realize on-line rapid replacement and maintenance;

1. Design standard: gb12237; 2. Structural length: gb12221; 3. Flange standard: JB / t79-94, gb9113.1-26. 4. Inspection test: JB / t9092-99;

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.
