EGR Valves
EGR valves regulate the flow of exhaust gases back into the engine intake system to help reduce NOx emissions in modern diesel engines. At Advanced Truck Parts, we supply EGR valves for Cummins, Detroit Diesel, Paccar, Volvo, Mack, and other heavy-duty diesel engines with fitment verification before purchase.

What an EGR Valve Does
An exhaust gas recirculation (EGR) valve controls the amount of exhaust gas that is redirected back into the engine intake. By regulating this flow, the valve helps lower combustion temperatures and reduce nitrogen oxide (NOx) emissions in diesel engines.
Common Engines Using EGR Valves
EGR valves are used across many heavy-duty diesel engines including:
- Cummins ISX, X15 and ISB 6.7 engines
- Detroit Diesel DD13, DD15 and DD16 engines
- Paccar MX-13 and MX-11 engines
- Volvo D11, D13 and D16 engines
- Mack MP7, MP8 and MP10 engines
- International A26 and MaxxForce engines
- Hino J08 and A09 engines
Common Signs of EGR Valve Failure
- Check engine or emissions warning lights
- Rough idle or poor engine performance
- Loss of engine power
- Increased exhaust smoke
- EGR-related fault codes
- Engine derate conditions
A faulty EGR valve can disrupt the emissions system and lead to performance problems, engine warning lights, and potential engine derate conditions.
Verify Fitment Before Ordering
EGR valves are engine-specific and emissions-system specific. To confirm compatibility quickly provide:
- Engine serial number
- Current EGR valve part number
- Truck VIN number
- Year / Make / Model of truck
- Photos of the valve tag if available
