Application of the Double Eccentric Butterfly valves
Double Eccentric Butterfly Valves, mainly used for water drainage in water plants, power plants, steel plants, smelting, chemical engineering, water source engineering, environmental facilities construction, etc.
It is especially suitable for use on water pipelines as regulating and interception equipment. Compared with the?centerline butterfly valve, the double eccentric butterfly valve is more resistant to high pressure, longer life and good stability. Compared with other valves, the larger the caliber, the lighter the material and
the lower the cost. But because there is a butterfly plate in the middle, the flow resistance is large, so a butterfly valve smaller than DN200 is not very meaningful.
Structural Features
- Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance.
- Eccentric structure is adopted to reduce the friction of the seal ring and prolong the service life of the valve.
- Fully sealed with zero leakage. Can be used in ultra-high vacuum conditions.
- Replace the valve plate seal ring, butterfly plate, shaft and other materials, which can be used for a variety of media and different temperatures.
