    Advantages

    1.Excellent Corrosion Resistance

    This high performance butterfly valve is manufactured from 304, 316 or 316L stainless steel, the valve resists acids, alkalis, salt spray, chemical solvents and seawater effectively. It hardly gets rusted, perfectly suited for pipelines conveying corrosive media.

    2.Outstanding Working Performance

    The triple eccentric design eliminates friction during operation. The metal hard seal ensures reliable bidirectional tight shutoff. It features great resistance to high temperature, high pressure, erosion and wear, delivering stable performance in harsh conditions.

    3.Sanitary & Versatile Application

    The metal to metal stainless steel material is clean and non-polluting, meeting sanitary standards for food and pharmaceutical industries. With a compact structure, it is compatible with various actuators for both manual and automated pipeline systems.
