Abstract
A sealing assembly for a valve with a rotary actuating shaft includes a top seal formed of a plastic diaphragm and a metal diaphragm, both of which are in sealing relationship with the actuating shaft. The metal diaphragm has a cantilever supported lip that is spring fitted into resiliently biased relationship with the actuating shaft. The sealing surface of the metal diaphragm provides a fire-tested seal in the event that the seal of the plastic seal is destroyed by fire.
