Metal seated butterfly valve is that both sides of the seal are made of metal material or other hard materials. This seal has relatively poor sealing performance, but is resistant to high temperatures, abrasion and mechanical properties. Metal seated is often combined of such as: steel + steel, steel + copper, steel + graphite, steel + alloy steel. The steel here may also be cast iron, c...

Metal seal butterfly valve means that both sides of the seal pair are made of metal material or other hard materials. The sealing performance is poor, but it is resistant to high temperature, abrasion and good mechanical properties. Such as: steel + steel; steel + copper; steel + graphite; steel + alloy steel. The steel here may also be cast iron, cast steel, alloy steel or alloys for surfacing an...
