The electric triple eccentric butterfly valve adopts a three-dimensional eccentric structure, and has the advantages of strong applicability, small torque force, less friction, and good sealing performance. When the electric triple eccentric butterfly valve is opened, the disc will instantly separates the sealing surface of the seat, which reduces friction and interference with the sealing surface, and greatly improves the service life of the butterfly valve. Moreover, the electric triple eccentric butterfly valve disc and the seat sealing surface are made of stainless steel, so that the butterfly valve has reliable guarantee of corrosion resistance, temperature resistance, pressure resistance and wear resistance, and is a high-performance energy-saving electric butterfly valve.The application range of the triple-eccentric disc valve can withstand pressure up to 2500 LB, temperature resistance as low as -196 ℃, as high as 700 ℃, seal reaches 0 leakage, regulation ratio up to 100:1 or more. That is to say, on all kinds of severe and critical process control pipelines, whether it is an on-off valve or a control valve, as long as the type is properly selected, the disc valve can now be used with confidence and low cost.
