Cummins EGR Valves
Cummins EGR valves play an important role in modern diesel emissions systems. The exhaust gas recirculation (EGR) valve regulates the amount of exhaust gas routed back into the intake system to reduce NOx emissions and maintain proper engine performance. At Advanced Truck Parts, we supply replacement EGR valves for Cummins engines including ISX, X15, and ISB 6.7 platforms.

Cummins EGR Valves by Engine Platform
Cummins diesel engines use electronically controlled EGR valves as part of the emissions control system. Proper EGR valve operation helps maintain combustion temperatures, improve emissions performance, and prevent fault codes.
Cummins ISX EGR Valves
The Cummins ISX engine platform uses EGR systems to control emissions on multiple engine generations. The EGR valve regulates exhaust gas flow between the exhaust manifold and intake system.
- Cummins ISX CM871
- Cummins ISX CM2250
- Cummins ISX CM2350
A failing EGR valve on ISX engines can cause rough engine operation, excessive soot buildup, or emissions-related fault codes.
Cummins X15 EGR Valves
The Cummins X15 engine uses advanced emissions technology including EGR and aftertreatment systems. The EGR valve works together with sensors and the engine control module to regulate exhaust gas flow.
- Cummins X15 Efficiency Series
- Cummins X15 Performance Series
Proper EGR valve function is critical for maintaining emissions compliance and preventing engine derate conditions.
Cummins ISB 6.7 EGR Valves
The Cummins ISB 6.7 engine is widely used in medium-duty trucks and diesel applications. These engines use electronically controlled EGR valves to regulate exhaust gas flow and control combustion temperatures.
- Cummins ISB 6.7 CM2150
- Cummins ISB 6.7 CM2350
- Medium-duty truck platforms
Common Cummins EGR Valve Failure Symptoms
- Check engine light related to EGR system
- Rough idle or poor engine performance
- Excessive soot buildup
- Engine derate conditions
- Increased emissions levels
EGR valve issues can affect both engine performance and emissions system operation, so early diagnosis and replacement are recommended.
Verify Fitment Before You Buy
Cummins EGR valves must match the engine model and emissions configuration. To confirm compatibility before ordering, provide:
- Engine Serial Number (ESN)
- Truck year / make / model
- Engine model (ISX, X15, or 6.7)
- Current EGR valve part number
This information allows our team to confirm the correct EGR valve for your Cummins engine.
