Valv e assembly for internal combustion engine system with turbomachinery

An internal combustion engine system comprising:

• a turbomachine;
• an exhaust conduit coupled to the turbomachine and configured to receive exhaust from the turbomachine;
• a first dosing module positioned along the exhaust conduit and configured to selectively dose reductant into the exhaust within the exhaust conduit;
• and
• a valve assembly positioned within the exhaust conduit downstream of the turbomachine and upstream of the first dosing module, the valve assembly being selectively actuatable between at least (i) a first position that allows the exhaust to flow at a first flow rate through the exhaust conduit, and (ii) a second position that allows the exhaust to flow at a second flow rate through the exhaust conduit.
