Seven characteristics of the telescopic welded bellows hard-sealed wear-resistant ball valve:
1. It has high temperature resistance and can work at a high temperature of 570℃ for a long time. 
2. It has the performance of high pressure resistance and can work for a long time under the working condition pressure level of 42MPa. 
3. It has good corrosion resistance and can meet the special requirements for the corrosion performance of the valve before and after the manufacture of coal water slurry. 
4. With high wear resistance, it can meet the special wear resistance requirements of the Rockwell hardness of the media particles to reach 52HRC. 
5. With two-way sealing performance, it can ensure the two-way sealing of the valve, which provides the necessary guarantee for online emergency repair of the valve. 
6. In terms of wear resistance and erosion resistance, spray-welded nickel-based tungsten carbide alloy with high temperature resistance, good abrasion resistance, high wear resistance and high bonding strength on the sealing surface of the ball and valve seat. 
7. The processing technology of superhard materials is innovative and has reached the domestic level.
