摘要
An isolation valve assembly including a valve body having an inlet and an outlet. The isolation valve includes a seal plate disposed within an interior cavity of the valve body. The seal plate is movable between a first position allowing gas flow from the inlet to the outlet, and a second position preventing gas flow from the inlet to the outlet. The isolation valve includes a closure element disposed within the valve body. The closure element is configured to retain the seal plate stationary in the first position or the second position. The closure element includes a first sealing element positioned adjacent to a first surface of the seal plate. A working surface of the first sealing element is substantially obscured from the gas flow when the seal plate is stationary.
