  • Product Description
  • Detailed parameters
  • The two-way metal hard seal butterfly valve is mainly composed of valve body, butterfly plate, valve shaft, valve body sealing ring, butterfly plate sealing ring, shaft sleeve, self-lubricating bearing, driving device, etc. It has the advantages of good two-way sealing performance and long life. It is the traditional butterfly valve replacement choice. It has the following characteristics:

    1, unique structure, small and light, easy to operate;

    2. Adopting three-dimensional eccentric structure, the butterfly plate and valve seat sealing surface have high machining accuracy. At the moment of opening the butterfly plate, the sealing surface is completely detached; the butterfly plate is almost frictionless during the closing process, and the closing is light. With more closed more tight self-locking function, self-sealing performance, sealing performance is stable and reliable;

    3. The sealing pair (butterfly plate sealing ring-valve body sealing ring) is made of stainless steel and has been specially treated. It has the dual advantages of metal hard sealing and elastic sealing, corrosion resistance, wear resistance, high temperature resistance and long service life;

    4. The design of "radial dynamic balance sealing structure" is adopted, which makes the opening resistance of the butterfly plate extremely small and reliably realizes the two-way sealing and zero leakage of the butterfly valve inlet and outlet. During the opening and closing process, the sealing surface of the butterfly plate can be completed instantly and quickly at each point along the 360 ° circumference, and the sealing action of closing contact automatically coincides with each other is realized quickly and accurately;

    5. The streamlined design of the butterfly plate has high strength, large flow area, small flow resistance and energy saving;

    6. Reliable two-way sealing function is an optional product that requires two-way cutting in the pipeline system]. It is not restricted by the flow direction of the medium or the space position during installation. It can be installed in any direction.

    Two-way metal sealing butterfly valve is a new type of butterfly valve developed and designed since 1997. The new series of butterfly valves scientifically adopt new technologies, new processes and high-quality materials to make the valve reliable, reduce and avoid maintenance during use, long service life, and good use efficiency and social benefits. Its products in the industry has a certain price advantage and technical advantages 1.2 manual two-way metal sealing butterfly valve, electric two-way metal sealing butterfly valve its technical performance and material not only fully meet and meet, but also higher and better than the relevant national standards and technical requirements, as well as product acceptance, delivery, installation and use requirements.
