Q41TC Ceramic Ball Valve/Q341TC Worm Gear Ceramic Ball Valve Q641TC Pneumatic Ceramic Ball Valve/Q941TC Electric Ceramic Ball Valve has remarkable characteristics of super corrosion resistance, high temperature resistance, wear resistance and erosion resistance. Widely used in petrochemical, metallurgical, papermaking, power plants, oil refining and other industries, all kinds of acid, alkali, salt gas, liquid, high temperature steam and mud transportation system. It is an ideal substitute for titanium valve and Monel valve under strong corrosion. Zirconia ceramic ball valve has the advantages of low cost, high operation economy and long service life (2-4 times as much as titanium valve). Its driving mode is manual, pneumatic, pneumatic, spring reset, electric and so on. All kinds of special ceramic valves can be designed according to the requirements of users. Suitable for all kinds of acid, alkali, salt liquid, gas medium environment, hard sealing valve is especially suitable for the environment with granular, fibrous medium.
Characteristic
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 ceramic ball valve has very high wear resistance, corrosion resistance, erosion resistance, and thermal insulation, thermal expansion is small.
2. The sphere is manufactured with advanced grinding equipment and technology. The sphere has high roundness precision and good surface quality. After grinding with the valve seat, the Zr02 ceramics can be used for self-lubrication to obtain good sealing performance.
3. Ceramic good wear resistance, so that the valve durable, high reliability, long service life, is titanium alloy valve and Monel valve 2-4 times.
4. 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 such media at present.
