975 001 000 0 Quick Release Valve for WABCO Systems

What does a quick release valve do?

This heavy-duty quick release valve serves as a critical component in the pneumatic brake system of heavy commercial vehicles, facilitating the rapid venting of compressed air from the brake chambers. By allowing air to exhaust directly to the atmosphere rather than traveling back through long delivery lines, it significantly reduces brake release lag. This ensures that the brake linings disengage instantly when the pedal is released, contributing to safer operation and preventing brake overheating.

System compatibility and design

This valve is designed to be compatible with WABCO systems and is engineered to meet strict OE dimensions. It features a robust construction suitable for demanding environments, ensuring reliable performance in heavy commercial vehicle brake circuits. The component is optimized for high-pressure stability within its specified operating range.

Technical specifications and installation

The unit features M22x1,5 port connections and is rated for a maximum pressure of 10 BAR. For optimal performance, technicians should ensure all air lines are clear and connections are tightened to specification during installation. Regular inspection of the valve assembly helps prevent delays in brake release and maintains system integrity.

Maintenance and troubleshooting

Monitoring the braking response time can help identify when a replacement is necessary. If there is a noticeable delay in brake release or uneven braking across axles, checking the integrity of the quick release valve is a recommended maintenance step.

OE cross-reference

301.07.0002 (Quick Release Valve) is the equivalent of the WABCO OE number. This part directly replaces WABCO OE number 9750010000.
