DAF Genuine Back Pressure Valve
Controlled exhaust performance for reliable regeneration and maximum uptime
The Back Pressure Valve, or BPV, is a key component in the exhaust aftertreatment system of modern DAF engines. It controls exhaust gas pressure and helps the Exhaust Aftertreatment System reach the temperatures needed for correct regeneration.
The DAF Genuine BPV is developed and validated by DAF engineers as part of the complete exhaust and aftertreatment system. It meets the highest DAF quality requirements and is the best choice for new DAF trucks where reliable performance, durability and system protection are essential.
How regeneration works
During regeneration, the Diesel Particulate Filter, or DPF, must reach a high temperature to burn off collected soot.
The BPV supports this process in two important steps:
- The BPV increases exhaust back pressure, causing the engine to work harder and generate more heat. This helps raise the exhaust gas temperature to approximately 270°C, which is required to initiate the regeneration process.
- The seventh injector then injects fuel to raise the temperature of the Exhaust Aftertreatment System to approximately 600°C, allowing the soot in the DPF to be burned off.
The BPV is essential during the first step. If it cannot create the correct conditions, the required starting temperature is not reached and regeneration cannot begin.
Designed as part of the complete DAF system
The BPV does not work on its own. It operates within the complete exhaust and engine management system, together with:
- the Turbocharger
- the VTG actuator
- the EGR valve
- the Engine Control Unit
- the Exhaust Aftertreatment System
All these components must work together to control exhaust flow, temperature and engine operation. The DAF Genuine BPV is developed as part of this complete system, helping every component perform as intended.
Why correct BPV operation matters
If the BPV fails or does not operate correctly, the system may not reach the temperature needed to start regeneration.
This can lead to:
- additional soot build-up in the DPF
- an incomplete or blocked regeneration process
- reduced engine performance
- increased fuel consumption
- a clogged DPF
- unplanned workshop visits and downtime
A correctly functioning BPV helps keep the aftertreatment system clean, protects engine performance and supports long-term uptime.
Key advantages of the DAF Genuine BPV

1. Complete and correct assembly
The DAF Genuine BPV is supplied complete with the actuator and, where applicable, the correct heatshield. This supports correct exhaust flow and protects nearby aftertreatment components.
2. Developed for the complete DAF system
Designed and validated by DAF engineers to work in balance with the turbocharger, VTG actuator, EGR valve, engine ECU and aftertreatment system.
3. Improved protection against electrical stress
The updated actuator PCB provides better resistance to electrical overstress.
4. High temperature bearing and shaft
The bearing and shaft are manufactured from special sintered material, specifically selected to withstand exhaust temperatures up to 600°C. This material choice ensures stable movement, reduced wear and long term durability under thermal load.
The improved coolant line connection helps prevent leakage and actuator overheating, reducing the risk of vehicle breakdown.
The upgraded 16-bit control system provides faster response and reduced overshoot. This supports precise valve positioning and stable exhaust system performance.
Produced under controlled conditions
Each new DAF Genuine BPV is produced under controlled manufacturing conditions. This helps protect the exhaust system against contamination and assembly issues.
Do not compromise on system performance
The BPV is a system-critical component. Differences in material quality, cleanliness, electronics and assembly can directly affect exhaust flow, aftertreatment performance and vehicle uptime.
Remanufactured or non-genuine alternatives may include incorrect components, unfinished sealing surfaces, contamination or missing protective parts. These differences can lead to leakage, increased wear, disturbed exhaust flow or higher heat exposure for nearby sensors and cables.
Choose the BPV designed, tested and integrated as part of the complete DAF system.
