These rubber seals are very vital component of butterfly valve and dome valve since these regulates the flow of fly Ash. Inflatable seated butterfly or dome valves utilize an inflatable seat to create a seal around the disc or dome. Once the disc or dome is brought to the closed position, the seat is inflated pneumatically. As the seat is created after the disc or dome closes, less torque is required to move the disc or dome into the closed position. They are used to isolate and control flow of granular material.
