Double Eccentric Butterfly Valve
Introduction:
The double eccentric butterfly valve, also known as high-performance butterfly valve, is mainly used for drainage of systems such as water plants, power plants, steel plants, smelting, chemical industry, water source spring projects, environmental facilities construction, and especially for waterway pipelines, as a regulating and intercepting equipment. Compared with the center line butterfly valve, the double eccentric butterfly valve is more resistant to high pressure, has longer service life and good stability. Compared with other valves, the larger the diameter, the lighter the material, and the lower the cost. However, because there is a butterfly plate in the middle, the flow resistance is large, so the butterfly valve smaller than DN200 is meaningless.
Structural characteristics:
1 Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance.
2. The eccentric structure is adopted to reduce the friction of the sealing ring and prolong the service life of the valve.
3 Completely sealed with zero leakage. Can be used in ultra-high vacuum conditions
4 Replace the valve plate seal ring, butterfly plate, shaft and other materials, which can be used for various media and different temperatures
