Manual ceramic ball valve
1. All the parts in contact with the medium are structural ceramics, which have high chemical stability and hardness (Rockwell hardness HRC90), second only to diamond. Therefore, the valve has very high wear resistance, corrosion resistance, erosion resistance, and good thermal insulation, small thermal expansion.
2. The sphere is manufactured by advanced grinding equipment and technology. The sphere has high roundness accuracy and good surface quality. After grinding with the valve seat, the Zr02 ceramics can achieve good sealing performance by self-lubrication.
3. It completely changed the defects of metal hard sealing ball valve, such as easy leakage, high torque and corrosion resistance of sealing surface.
4. The good wear resistance of ceramics makes the valve durable and reliable. Its service life is long, 2-4 times as long as that of titanium alloy valve and Monel valve. This valve has incomparable absolute advantages for high hardness granular media or soft granular but corrosive media. It is also the only valve suitable for this kind of media at present.
