The application range of the three-eccentric butterfly valve has been able to withstand pressure up to 2500 pounds, temperature as low as -196 ° C up to 850 ° C, seal to 0 leakage, control ratio up to 100:1 or more. That is to say, in a variety of harsh and critical process control pipelines, whether it is an on-off valve or a control valve, as long as the selection is appropriate, butterfly valves can now be used safely and at low cost. The so-called three eccentricity refers to adding an angular eccentricity on the basis of the double eccentric structure, even if the sealing surface of the butterfly valve is inclined and conical. The characteristic of this structure is that the outside of the periphery of the butterfly plate is processed into an external oblique cone, and the inside of the sealing valve seat is processed into an internal oblique cone.
