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

Widely used in chemical plant, pharmaceutical industry, water treatment, environmental protection and pickling process pipeline. Used for cut\u2011off and throttling regulation of acid, alkali, salt solution and various strong corrosive fluid media.<\/p><\/div>\n<\/div>\n

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

Wafer Type PTFE Lined Butterfly Valve realizes opening and closing by 90\u2011degree rotation of PTFE\u2011coated butterfly disc. When disc parallels pipeline direction, medium flows through; rotate 90 degrees, disc compresses PTFE liner seat to block flow passage and achieve tight shut\u2011off. Wafer structure is clamped between flanges, PTFE lining isolates medium from metal body to avoid chemical corrosion.<\/p><\/div>\n<\/div>\n
