This stainless steel triple eccentric butterfly valve adopts a three-offset structure with metal hard seal. It operates friction-free and achieves reliable bidirectional tight shutoff. Featuring excellent corrosion resistance, high temperature and pressure resistance, it works steadily with corrosive media. Compact in design, it is compatible with various actuators and ideal for chemical, food, pharmaceutical and seawater treatment systems.
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.
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.
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.
Standard export wooden case packaging
The high performance wafer butterfly valve is widely used in chemical pipelines for acids, alkalis and organic solvents. It also applies to seawater treatment, desalination projects and marine piping. Ideal for sanitary systems in food and pharmaceutical industries, as well as flue gas and wastewater lines in environmental desulfurization and denitrification facilities.

Our wafer butterfly valves are designed and manufactured in strict accordance with international standards, including API, EN, and JIS standards.
This valve features high temperature and pressure resistance, operating reliably within a broad temperature range of -190°C < T < 700°C.
The valve body can be constructed from WCB, QT450-10, Q235, Alloy Steel, or Stainless Steel (such as 304, 316, 316L). Stems and seats utilize high-grade stainless steel or cobalt-based hard alloys.
Yes. The triple offset (triple eccentric) structure combined with a metal-to-metal hard seal eliminates friction during operation and provides a zero-leakage bidirectional tight shutoff.
It is widely applied in chemical processing (acids, alkalis, solvents), seawater treatment & desalination, sanitary food & pharmaceutical lines, as well as desulfurization and denitrification flue gas/wastewater systems.
All valves are securely packaged using standard export wooden cases to ensure safe delivery and protect against damage during transit.
