Product Overview

The electric three-piece flange ceramic core ball valve is a high-performance valve that uses ceramic materials as the key sealing and flow components. It is driven by an electric actuator to rotate the valve core (ball), thereby achieving the opening and closing of the pipeline or the regulation of flow. The ceramic core endows the valve with extremely high wear resistance and corrosion resistance, making it suitable for harsh conditions. It is widely used in industries such as petrochemicals, metallurgy, papermaking, power stations, and coal mining, and can be used in various systems for transporting acids, alkalis, salts, gases, liquids, high-temperature steam, slurry, and ash, and is an important component for controlling the flow of media in these industries' pipeline systems.
