Q47FThe type 150 (LB) ～ 1500 (LB) fixed manual ball valve is suitable for chemical, petroleum, natural gas, metallurgy and other industries, as well as long-distance natural gas pipeline with hydrogen sulfide medium, impurities and serious corrosion.

1. The valve seat adopts spring structure, which pushes the valve seat to the ball to ensure good low-pressure sealing performance; 2. The valve seat before and after fixing the ball valve can be sealed, that is, the so-called two-way sealing feature. The inner cavity of the valve body can be discharged outwards by using the self-contained discharge valve; 3. The pivot adopts anti blowing protection structure and low friction coefficient bearing. It has excellent performance, high reliability and wide application;

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.
