Products Details

The soft-sealed flanged butterfly valve is a valve commonly used to control fluid flow and is designed and manufactured in accordance with a variety of national standards, such as GB/T12238-1989. This butterfly valve is rubber sealed, with carbon steel or stainless steel valve plate and stem, suitable for the temperature does not exceed 120℃ working conditions, widely used in textile, paper, food, medicine, chemical industry, petroleum, electricity, water supply and drainage, gas pipeline and other fields, for regulating flow and cutting media.

The construction features of the soft seal butterfly valve include a double eccentric structure, which makes the sealing performance of the valve more reliable when closed. The sealing material is usually stainless steel and oil-resistant rubber, which has a long service life. The rubber sealing ring can be installed on the valve body or the butterfly plate, and the user can choose according to the different media needs. The butterfly plate adopts the frame structure, which has high strength, large flow channel and small flow resistance.

In addition, the valve body of the soft-seal butterfly valve has a bi-directional sealing function, which can be installed in any direction, and is not limited by the flow direction and spatial position of the medium. The valve also has a unique structural design, flexible operation, labor saving and convenient.

The soft-seal butterfly valve also has intelligent features, such as electric control, with adjustment, switching functions, and is equipped with double limit protection, overheat protection and overload protection, providing full travel time of 15 seconds, 30 seconds, 45 seconds, 60 seconds, and manual function.

In the selection of materials, the soft seal butterfly valve can be customized according to user needs, such as valve stem material, handle lever, sleeve, sealing ring, valve body and butterfly plate and other components of the material can be selected according to the requirements of the working condition. In addition, a variety of optional parameters are provided, such as temperature range, pressure rating, specifications, flange connection standards and construction forms.

In general, the soft sealed flanged butterfly valve has become an important component of fluid control in industrial systems due to its compact structure, easy operation, reliable sealing and wide application range.
