Eccentic Segment Ball Flange Connections Ball Valve

Product Overview

The eccentric sector ball flange connection ball valve is an innovative control valve that combines the eccentric sector ball structure with standard flange connection. This product, through its unique eccentric shaft design and V-shaped fan-shaped ball, perfectly resolves the wear and cavitation issues of traditional ball valves under regulating conditions. It combines outstanding shut-off performance with precise flow regulation capability, making it an ideal solution for regulating and shut-off applications in harsh working conditions.

Technical specifications

Product features
