Imports of hard-sealed butterfly valve (Metal Seated Butterfly Valve) Overview: Imported hard-sealed butterfly valve structure using three-dimensional design of the principle of the core, the valve seat with hard and soft seal-compatible multi-level structure, exquisite workmanship and advanced technology. The product from the valve body, disc, multi-level valve seat, stem, transmission and other major components. Therefore, it is widely used in metallurgy, electric power, petroleum, chemical, air, gas, combustible gas and plumbing and other corrosive media pipeline. With a safe, reliable, small flow resistance, high temperature for corrosive media and so on. Can be used as regulation and shut-off devices, widely used in steam, hot water, water, oil, gas, natural gas, chemicals, acid and alkali salts and other process piping. Imported hard seal butterfly valve features: As imported hard seal butterfly valve is the use of three-dimensional design of the eccentric principle of the sealing surface to achieve the ideal trajectory of space movement, the sealing surface without friction between each other, without interference, coupled with the selection of sealing materials, so that Butterfly valve sealing, corrosion resistance, high temperature resistance and wear resistance has been a reliable guarantee. 1. Opening torque is small, flexible and convenient, saving energy. 2. Three-dimensional structure of the heart, so that the more closed off the disc more tight, reliable sealing performance, to no leakage. 3. High pressure, corrosion-resistant, wear-resistant, long life and so on. 4. Reasonable design, compact structure, quick opening and closing. 5. Opening torque is small, non-friction seal rotation, the valve life is long. 6. Replace the valve body material and seal sandwich can be applied to different media.
