Techinical Info

The back pressure valve (Back Pressure Valve, BPV) with OE code 2123995 is an electric butterfly valve installed in the exhaust line of DAF Euro 6 vehicles with PACCAR MX-13/MX-11 engines. The assembly integrates the butterfly body and an electronic actuator with position sensor. Control is via CAN and it cooperates with the variable geometry turbocharger (VTG) and EGR in the engine air management.

Technical specifications

  • Type: exhaust butterfly (BPV) with integrated electric actuator and position sensor.
  • Actuator cooling: engine coolant circuit (increases durability).
  • Control: electronic, closed-loop control via ECU (CAN network).
  • Positioning: exhaust line, upstream of the aftertreatment (DOC/DPF/SCR) in Euro 6 layouts.
  • Cooperative function: integrated with VTG and EGR to manage flows and exhaust temperatures.

DIPA can intervene to overhaul these parts thanks to its experience and expertise.

Functionality

  • DPF regeneration: creates back pressure to raise and stabilize exhaust temperature during regenerations (parked and active).
  • Cold warm-up: accelerates warming of the engine and aftertreatment, reducing cold-start emissions.
  • Air management: together with VTG and EGR, it modulates the composition/flow of gases toward the EAS (DOC/DPF/SCR) to meet NOx/PM targets.
  • Engine brake: contributes to braking power in combination with VTG and integrated brake systems (butterfly closing strategy on the exhaust).

Model applications

  • DAF XF

Typical faults and causes

  • Wear/failure of the electric actuator: position errors, out of calibration, overheating.
  • Seized butterfly or linkages: carbon/oil deposits that obstruct movement.
  • Air leaks/wiring: false contacts in the connector, power supply or CAN network issues.
  • Regeneration malfunctions: unstable back pressure with rpm oscillations and interrupted regenerations.
  • Mechanical damage/vibrations: play on the butterfly shaft or fractures of the valve body.

Final conclusions

The DAF BPV 2123995 is a key component for thermal and emissions management of DAF MX Euro 6 engines. Actuator failures or seized butterfly movement compromise DPF regenerations, braking response and the reliability of the aftertreatment system.
