Morphology
The meaning is directly compositional: 'exhaust' (engine gases) + 'valve' (a flow-control device) clearly yields a valve for exhaust gases. This noun–noun technical compound follows common, cross-linguistic compound patterns, so a B1 learner who knows both constituents will readily infer the intended meaning.
Etymology
Exhaust valve combines exhaust (the 'used gas' from an engine) and valve (a small gate). It is the gate that opens to let the used gas out of the engine, so the name explains the part's job today.
