Product description
is composed of rotary electric actuator and triple eccentric butterfly valve body. The valve body adopts triple eccentric metal hard seal structure, and the valve seat and sealing surface are made of all stainless steel, which has good corrosion resistance and two-way sealing function. The electric triple eccentric butterfly valve has the characteristics of less friction between the butterfly plate and the valve seat, long service life, wide application range and convenient maintenance. Electric triple eccentric butterfly valves are widely used in petroleum, chemical industry, electric power, metallurgy, iron and steel, paper making, medicine, food, textile, light industry and other industries.
Main characteristics of electric triple eccentric butterfly valve
1. The valve adopts triple eccentric sealing structure, and the wear of valve seat and butterfly plate is small.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life, regardless of low temperature and high temperature.
3. The butterfly plate sealing surface is made of surfacing cobalt-based cemented carbide, which is wear-resistant and has a long service life.
4. Large-diameter butterfly plate adopts the truss structure, which has high strength, large flow area and small flow resistance.
5. The electric triple eccentric butterfly valve has bidirectional sealing function, which is not limited by the flow direction of medium or affected by the spatial position during installation, and can be installed in any direction.
6. The driving device can be installed in multiple stations (rotating 90 or 180), which is convenient for users to use.
