Product Overview

The UPVC pneumatic flange ceramic core ball valve is a special type of valve that combines an UPVC (high-density polyvinyl chloride) body with a high-performance ceramic core. It is driven by an air actuator to achieve rapid opening and closing or flow regulation. The core components (ball and valve seat) are made of ceramic materials, which combine the corrosion resistance of UPVC and the wear resistance of ceramics. It is suitable for harsh corrosive, high-wear and particle-containing medium conditions and is widely used in fields such as chemical industry, metallurgy, environmental protection, and wastewater treatment.
