Product Overview

The pneumatic three-segment flanged ceramic core ball valve is a high-performance industrial valve specially designed for harsh conditions. It combines the wear-resistant and corrosion-resistant properties of ceramic materials with the rapid response capability of the pneumatic actuator. It is widely used in industries such as petrochemicals, metallurgy, papermaking, power stations, coal mining, mining, and environmental protection, and can be used in various systems for transporting acids, alkalis, salts, gases, liquids, high-temperature steam, slurry, and ash, as well as for regulating flow or cutting off media.
