The ball wear resistance, corrosion resistance, easy to start, and has a self-cleaning function, suitable for piping system conveying slurry or impurity liquid.
Product features:
■ all parts in contact with the media are structural ceramic materials, their chemical stability and high hardness (Rockwell hardness HRC90), second only to diamond, therefore, this valve has a very high wear resistance, corrosion resistance, erosion resistance, and good insulation, thermal expansion.
■ ball grinding equipment and advanced manufacturing technology, high precision ball roundness, surface quality, and the seat of the self-lubricating property of ZrO2 ceramics research, can be achieved very good sealing performance.
A good wear resistance of ceramic, so that the valve durability, high reliability, long service life.
■ ceramic ball core has high hardness, high strength, high wear resistance and good corrosion resistance, can switch used in strong corrosion and wear of fluid medium and regulating such harsh conditions.
■ in high hardness of the particle medium, or soft particles, but there are corrosive medium, the valve has the absolute advantage, has been widely used for flue gas desulfurization system, slag removal system and combustion system of power plant: saline, distillation process of soda; pulp mill control system.
