Abstract
A valve includes an annular body defining a body bore. An annular valve seat is positioned in the body bore and an annular groove is defined in a portion of the annular sealing surface. A rotatable valve element is positioned in the body bore. With the valve element in a closed and an unpressurized condition, the annular groove is deformed and a first groove gap is defined in the annular groove adjacent to the first disc face and a second groove gap is defined in the annular groove adjacent to the second disc face. With the valve element closed and in a pressurized condition, the annular groove is deformed and a third groove gap is defined in the annular groove adjacent to the first disc face. A volume of the third groove gap is greater than a volume of the first groove gap and second groove gap.
