The structure of electric two-way pressure butterfly valve selects three-dimensional knitting principle planning, the valve seat selects hard and soft seal compatible multilevel structure, processing exquisite, advanced technology. Electric bidirectional pressure butterfly valve consists of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other primary components. Therefore, electric two-way pressure butterfly valve is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gases and water supply and drainage and other corrosive media pipeline.
