ABSTRACT:
The present invention is directed to an exhaust gas control (EGC) valve. The EGC valve comprises a valve housing having at least one inlet port, at least one outlet port, and a flow channel having a centerline extending between the ports. A valve seat is adjacent an opening in the at least one outlet port. The EGC valve further comprises a rotatable actuator shaft offset from the centerline. At least one L-shaped valve armature is operably connected to the actuator shaft. The valve armature has a first leg and a second leg. The first leg is connected to the actuator shaft so that rotation of the actuator shaft in a first direction positions the second leg into sealing engagement with the valve seat to close the flow channel.
