Top entry butterfly valve is a new butterfly valve developed on the basis of three eccentric multi-layer metal hard seal butterfly valve. In addition to all the excellent performance of three eccentric multi-layer metal hard seal butterfly valve, it can also bear pressure in both directions, and one of the biggest advantages of this top-mounted butterfly valve is that it can be realized on-site maintenance. With the selection of valve body materials, the use of temperature can be from -29℃ ~ 550℃, due to its good flow characteristics, can be closed to cut off the medium, but also can be adjusted at will the flow of the medium. Scope of application top-mounted butterfly valve is suitable for medium temperature -29°C-600℃, nominal pressure of 0.6~2.5MPa medium for water, steam, oil, hot air, corrosive and other pipelines, in order to achieve the purpose of cutting off the fluid and regulating the flow of the medium, is the best opening and closing mechanism of various pipelines.
