text: Since damper authority affects the installed characteristic curve of an ideal duct-damper path, which has a controlled differential static pressure between its two connected nodes, in order to obtain an approximate linear installed characteristic curve, a parallel-blade damper is preferred for the paths with high damper authority and an opposed-blade damper is preferred for the paths with low damper authority (ASHRAE 2010c; Lizardos and Elovitz 2000).
