\n
Applications<\/p>\n
<\/div>\n

Widely used in power plant, metallurgy, cement plant, waste incineration, chemical industry. Apply to flue gas, dust\u2011containing gas, high\u2011temperature steam and abrasive medium pipeline for cut\u2011off and regulation control.<\/p><\/div>\n<\/div>\n

\n
Working Principle<\/p>\n
<\/div>\n

Metal Seated Butterfly Valve realizes opening and closing by rotating butterfly disc within 90 degrees. The metal disc closely fits metal seat to achieve hard sealing. When disc parallels pipeline direction, medium passes through; rotate 90\u00b0, disc presses seat to block fluid passage and complete shut\u2011off. Metal hard\u2011seal structure keeps stable performance under high temperature and particle\u2011containing medium.<\/p><\/div>\n<\/div>\n
