CBETBTriple Eccentric Hard Seal Butterfly Valve

Product Application

This butterfly valve is suitable for food, pharmaceuticals, petrochemicals, power plants, steel mills, industrial environmental water treatment, high-rise buildings, and water supply and drainage pipelines. It is an ideal device for regulating flow and cutting off fluid.

Product Features

1、This butterfly valve is a new generation product developed by absorbing and digesting foreign technology, combined with domestic user feedback and accumulated production experience.

2、It adopts a triple eccentric structure, and the valve body sealing ring uses a multi-layer sealing ring structure, ensuring uniform and reliable contact between the disc and the valve body sealing surface, achieving gas sealing with zero leakage.

3、Unique structure, flexible operation, labor-saving, convenient, and long service life.

4、Triple eccentric design with high temperature resistance, corrosion resistance, and wear resistance.
