Double eccentric butterfly valves, also known as high-performance butterfly valves, are mainly used for system drainage in water plants, power plants, steel mills, chemical industry, water source and spring engineering, environmental facility construction, etc. They are especially suitable for use as regulating and intercepting equipment on waterway pipelines. Compared with the centerline butterfly valve, the double eccentric butterfly valve is more high-pressure resistant, has a longer lifespan, and has better stability.

• Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance.

• Adopting an eccentric structure to reduce the friction of the sealing ring and extend its service life.

• The valve plate sealing ring adopts a T-shaped structure, and the sealing pair is linearly sealed.

• Completely sealed with zero leakage.

• Replace the material of valve plate sealing ring, "0" ring, valve plate, shaft and other components, which can be suitable for various media and different temperatures.
