Description

What does an unloader valve do?

This unloader valve plays a critical role in regulating air pressure within the pneumatic brake system. By managing the air flow, it ensures that the compressor can maintain the correct operating pressure required for safe braking performance and system stability in heavy commercial vehicles.

Vehicle compatibility and fitment

This component is specifically designed for DAF vehicles, ensuring seamless integration with existing pneumatic circuits. It maintains optimal pressure regulation to support the braking and air suspension functions of the vehicle.

Technical specifications and installation

The technical configuration includes M22x1.5 and M12x1.5 port sizes, providing precise fitment for heavy-duty applications. Technicians should verify the cut-out pressure of 8.1 BAR / 0.2 BAR during installation to ensure the valve operates within the correct pneumatic parameters.

Maintenance and troubleshooting

Regular inspection of the inflation valve functionality is recommended during routine maintenance to prevent pressure drops in the system.

OE cross-reference

301.01.0002 (Unloader Valve) is the equivalent of the DAF OE number. This part directly replaces DAF OE number 285768.
