Product Overview

The manual three-piece flanged ceramic core ball valve is an industrial valve specifically designed for extremely harsh working conditions. Its core feature is that the valve body consists of three parts and connects to pipelines via flanges. The critical sealing components (ball and seat) are manufactured from high-performance engineering ceramic materials, and the valve is operated manually to control the flow of media. It is widely used in industries such as power, mining and metallurgy, chemical and petrochemical, polysilicon and photovoltaic, cement and ceramics, environmental protection and desulfurization/denitrification, among others, for regulating flow or cutting off media.
