Abstract
A stack damper valve comprising a pair of semicircular steel discs typically joined by a removable piano-type hinge. Each of the discs pivot upwardly in the direction of flow from a closed to an open position and vice versa. In the closed position the discs seat in a metal-to-metal relationship against a circular truncated steel seat which is secured such as by welding to the inner surface of the steel stack in which the valve is mounted.
