Abstract
An aspect includes a dual valve system that includes a first valve body and a first valve disc operably disposed within the first valve body, where the first valve disc has a first disc geometry. The dual valve system also includes a second valve body and a second valve disc operably disposed within the second valve body, where the second valve disc has a second disc geometry. The dual valve system further includes a mechanical linkage operably coupled to the first valve disc and the second valve disc, where the second disc geometry differs from the first disc geometry such that opening of a first flow area between the first valve body and the first valve disc occurs prior to opening of a second flow area between the second valve body and the second valve disc responsive to movement of the mechanical linkage.
