Description

What does an unloader valve do?

This unloader valve plays a critical role in the pneumatic control of heavy commercial vehicle air brake systems. By managing air flow and pressure regulation, it ensures the stability of the pneumatic circuits required for safe operation and braking performance.

Vehicle compatibility

This component is specifically designed for use in DAF trucks. It maintains high-strength performance under heavy-duty conditions, providing reliable pressure management within the vehicle's air system.

Technical specifications

The unit features specific port dimensions, including M22x1.5 for Port 1 and Port 21, and M12x1.5 for Ports 4, 22, and 23. Maintenance technicians should verify these thread sizes and the cut-out pressure of 8.1 BAR / 0.2 BAR during installation to ensure correct system calibration.

Maintenance guidance

Proper installation of this unloader valve helps prevent pressure fluctuations in the brake system. Regular inspection of the inflation valve functionality is recommended to maintain optimal pneumatic circuit integrity.

OE cross-reference

301.01.0002 (Unloader Valve) is the equivalent of the DAF OE number. This part directly replaces DAF OE number 0075038.
