1. The butterfly plate sealing ring is a soft and hard laminated metal sheet, which has the double advantages of hard sealing and elastic sealing. It has excellent sealing performance both in low temperature and high temperature.2. Using the three-dimensional eccentric structure, the seat and butterfly plate are almost friction-free, and have the sealing function with the closer and tighter.
3. Body airtight cover, use of stacking stainless steel, cobalt base hard alloy, sealing surface wear resistance, long service life.
4. The structure is unique, the operation is flexible, the labor-saving, convenient, is not subjected to the medium pressure high, the low impact, the sealing performance is reliable, the service life is long.
