Applications<\/p>\n

<\/div>\n

Mainly applied in power plant, metallurgy, cement, waste incineration and chemical industry. Suitable for high\u2011temperature flue gas, dust\u2011containing gas, steam and abrasive medium pipeline for cut\u2011off and throttling regulation.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Working Principle<\/p>\n

<\/div>\n

Metal Seated Wafer Butterfly Valve realizes opening and closing through 90\u2011degree rotation of butterfly disc. Disc parallel with pipeline enables medium flow; rotate 90\u00b0, disc compresses metal seat to block flow channel and achieve hard\u2011seal shut\u2011off. Wafer type is clamped between pipe flanges without extra flange connection, realizing compact installation.<\/p>\n<\/div>\n<\/div>\n
