structural features1, the product has a novel structure design, small overall size, light weight, easy maintenance, etc.;2, due to the optimization of the dual eccentric sealing structure data in design, making the seal with the valve seat sliding contact with the sealing surface of the wear and tear is reduced to a minimum, and completely eliminate the phenomenon of gnawing seals, thus greatly improving the life of the product;3, due to the the double eccentric sealing structure optimization design makes the product has a two-way pressure performance, fully applicable to the pipe-line bidirectional pressure requirements.4, due to the the double eccentric sealing structure optimization design, makes excellent products sealing performance (fully achieve zero leakage); operating light effort (operating torque only on the market for less than 70% of the similar products), flexible, safe and reliable;5 rubber seals installed in the butterfly board, without dismantling the valve to replace the seals;6, the sealing material aging resistance, resistance to corrosion, long service life.Scope Applicable pipeline in petroleum, metallurgy, chemical industry, food, medicine, pharmaceutical, water and electricity, ship, municipal engineering and water supply and drainage system, especially suitable for the pipe-line bidirectional pressure requirements. Adjusting and closure devices can be in a variety of corrosive and non-corrosive gas, liquid, semiliquid and solid powder pipelines and containers as used.
