Abstract: Described are isolation valves, and chamber systems incorporating and methods of using the isolation valves. In some embodiments, an isolation valve may include a valve body and a flapper assembly. The valve body may define a first fluid volume, a second fluid volume, and a seating surface. The flapper assembly may include a flapper disposed inside the valve body having a flapper surface complimentary to the seating surface.
