Ductile iron Double eccentric Flanged butterfly valves DN900

Ductile iron Double eccentric Flanged butterfly valve DN900

Double eccentric flanged resilient sealing butterfly valve is operated by the disc rotaing from 0 to 90.can be applied to cutoff or regulate the flow of media . Vireous enamel is available upon request .valve can be actuated by operating lever, handle wheel, electric actuator or pneumatic actuator

Professional design:

When init iating the rotary opening movement the disc is off-seated after only few degree

Of opening movement and there is very little wear and tear between seat ring and disc.

 Stainless steel seatring is rolled into the valve body by applying special rilling technology when

DN ≤ 1200.Uitrasonic spray applies seall of valve body when DN ≥1400

 Body and discmade of ductile iron which promote the impact resistance and pressure-bearing capacity; sealing ring made of rubberand valve seat’s sealing ring surface is conicalshaped , make the sealing capacity more reliable .

 Excellent corrosion protection:

 Inside electrostatic epoxyesin powder coating or vitreous enamel(upon request ), outside electrostatic epoxy resin powder coating

 Reliable health nature :

Epoxy resin powder is up to the health standard GB/T 17219-1998
