Applications<\/p>\n

<\/div>\n

Suitable for chemical plant, marine pipeline, seawater treatment, metallurgy and waste incineration system. Used for shut\u2011off and throttling control of corrosive gas, high\u2011temperature flue gas, salt\u2011containing medium and abrasive fluid.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Working Principle<\/p>\n

<\/div>\n

Stainless Steel Metal Seated Butterfly Valve completes opening and closing by 90\u2011degree rotation of stainless steel disc. When disc is parallel to pipeline, medium flows through; rotating 90 degrees makes disc tightly press metal seat to realize tight shut\u2011off. Stainless steel material prevents chemical corrosion, metal hard\u2011seat guarantees reliable sealing under high\u2011temperature abrasive conditions.<\/p>\n<\/div>\n<\/div>\n
