Product Overview

The three-piece pneumatic ceramic core ball valve is a type of valve that uses structural ceramics as the sealing pair or valve core and valve seat. It is specially designed for high wear and strong corrosive conditions. Driven by pneumatic power, it has excellent corrosion resistance and wear resistance, and is suitable for various industrial fields such as power, metallurgy, chemical industry, and mining. It can be used to cut off or connect the medium in the pipeline, and can also be used to regulate the flow rate.
