  • Flange butterfly valve

    Flange butterfly valve

    Flanged butterfly valves are particularly suitable for large-diameter valves and are widely used in large-diameter regulating fields. The fully open flanged butterfly valve can reduce the flow resistance. When the opening angle of the butterfly plate is about 15-70 °, the flange butterfly valve can control the flow of medium very sensitively. Classification of flange butterfly valve: according to the material of sealing surface, butterfly valve can be divided into soft sealing flange butterfly valve and hard sealing flange butterfly valve. The butterfly valve seat uses embedded O-ring or fluororesin as gasket to form a seal. Therefore, in order to ensure the sealing performance of the butterfly valve, it has the function of self-correcting temperature difference and wear. Flange butterfly valve is mainly used in industrial production pipeline, and its function is to prevent medium flow in the pipeline or adjust the size of medium flow in the pipeline.

  • Hard seal butterfly valve

    Hard seal butterfly valve

    Hard seal butterfly valve is simple in structure, small in size, light in weight and only composed of several parts. The sealing ring of hard seal butterfly valve is made of stainless steel, which has two advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life, regardless of low temperature or high temperature. Hard seal butterfly valve is a kind of valve that can open and close the pipeline by rotating the circular butterfly plate (sealing part) according to the rotation of the valve shaft. It is mainly used as a stop valve, also as a stop valve and a throttle valve, and has a regulating function. Nowadays, hard-sealed butterfly valves are increasingly used in low-pressure, large-diameter and medium-diameter pipelines. The butterfly plate of the hard seal butterfly valve is installed on the radial direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc butterfly plate rotates around the axis and the rotation angle is 0 ° to 90 °. When the rotation reaches 90 °, the valve can be fully opened. Our hard seal butterfly valve is affordable and long-term supply. Welcome to leave a message or call in the lower right corner.

  • Soft seal butterfly valve

    Soft seal butterfly valve

    The mid-range butterfly valve using polytetrafluoroethylene or rubber as the sealing material is called the soft seal butterfly valve. According to the different connection methods, the soft seal butterfly valve can be divided into flange type soft seal butterfly valve, wafer type soft seal butterfly valve and welding type soft seal butterfly valve. It is not only cheaper than multi-level metal hard seal butterfly valve, but also has excellent sealing performance. Air pressure test or water pressure test can reach the zero leakage standard. This type of soft seal valve adopts the center line vertical plate structure. Both ends of the structure are symmetrical around the valve stem. There is no two-way seal structure that can distinguish the flow direction. It is also a two-way soft seal butterfly. Butterfly valve is applicable to two-way opening and closing and adjustment of ventilation and dust collection pipelines, water treatment, light industry, petroleum, chemical industry and other industries.
