Western Rubbers’ inflatable seals are ideal for butterfly valves. Butterfly valves are used influid handling systems dealing in highly abrasive material, slurries, etc., to stop or regulate the flow of material, most often for maintenance or safety purposes.The sealing mechanism is a disc which, when the valve is closed, engages with the inflatable seal which inflates radially inward and completely blocks off the passageway, ensuring a leak proof environment. When the valve is opened, the disc turns 90° to allow the material to pass through.
