The unique design of the expansion butterfly valve uses gas pressure to extend the valve seat toward the valve disc to provide a smooth distribution of pressure to the seal at all times. Since only momentary contact occurs between the valve disc and the valve seat during the opening and closing of the valve, the valve disc is only slightly bumped. On the contrary, for the general butterfly valve, the collision caused by the valve disc rubbing the valve seat will reduce the performance and life of the valve.
