Double Offset Butterfly Valve
Description of Double Offset Butterfly Valve:
ZECO is further improved on the basis of single eccentric butterfly valve. The stem axis of single eccentric butterfly valve is deviated from the center of butterfly disc. When the valve is opened, the upper and lower ends of butterfly disc are no longer as laborious as the center line butterfly valve, but the friction with the seat still exists. The improved feature of double offset butterfly valve is that the stem axis deviates from the center of the disc and the center of the stem itself, just like the single eccentric butterfly valve.
Such a structure can make the disc escape from the seat immediately after the valve is opened, and there will be no friction between the disc and the seat after the single eccentric butterfly valve is opened. ZECO is a manufacturer specializing in the production of metal to metal seal butterfly valve, and the double offset butterfly valve with metal seat is more conducive to high temperature resistance, which has contributed to the application of butterfly valve in the high temperature field.
