Double eccentric Butterfly valve features
- Double eccentric butterfly valve is also called high-performance butterfly valve, which is mainly used for water drainage in water plants, power plants, steel smelting, chemical industry, water source engineering, environmental facilities construction, etc.
- It is especially suitable for waterway pipelines as regulating and shut-off equipment.
- Compared with the center-line butterfly valve, the double eccentric butterfly valve is more resistant to high pressure, longer life and better stability.
- Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance.
- the eccentric structure is adopted to reduce the friction of the sealing ring and prolong the service life of the valve.
- Completely sealed with zero leakage. Can be used in ultra-high vacuum conditions
- Replace the valve plate seal ring, butterfly plate, rotating shaft and other materials, applicable to multiple media and different temperatures
