利用三個偏心的結構，使閥門啟閉時閥板與閥座間幾乎沒有庫擦，杜絕了普通閥門打開時所 出現的跳躍現象，從。度開始即進入可調區域，直至90度全開，其正常可調比是普通蝶閥的2倍以 上，可調比■高可達100:1,這為偏心蝶閥作為調控閥使創造了解的釧牛。
Using the three eccentric structures, there is little friction between valve plate and valve seat when the valve is open and close, which can eliminate the jumping phenomenon when the valve is opened. Adjustable range is from 0 degree to 90 degrees, and its normal adjustable ratio is 2 times more than ordinary butterfly valve, and adjustable ratio is up to 100:1.
This creates the good condition for the eccentric butterfly valve as a control valve.
