Inflatable seals for butterfly valves are suitable for Rubber Seals & Gaskets. Butterfly valves are used by powerful handling systems that deal with highly abrasive material, slurries, etc. to interrupt or control material movement, most often for repair or safety purposes. The sealing mechanism is a disk that engages with the inflatable seal when the valve is closed, which inflates radially inward and blocks the passage entirely, ensuring a leak-proof area. The disk turns 90 ° when the valve is opened to allow the material to move through.
