301.07.0022 Quick Release Valve for Volvo

What does a quick release valve do?

This quick release valve is a critical component within the pneumatic brake system of heavy commercial vehicles, designed to rapidly vent compressed air from the brake chambers the moment the pedal is released. By reducing the air lag caused by long lines, it ensures the brake linings disengage instantly, improving overall safety and response times.

Compatible vehicles and engines

This component is compatible with Volvo models including F10, F12, F7, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12 engines such as TD100, TD120, D10A, and D12A. It is also fitted to Alexander Dennis vehicles and is compatible with WABCO systems.

Installation and maintenance

Installation requires careful attention to the port configurations to ensure a leak-free seal. This specific unit features M22x1,5 VOSS connections on all ports and is rated for a maximum operating pressure of 12 BAR. Technicians should verify that all connections are tightened to specification to maintain system integrity.

Troubleshooting and selection

Regular inspection of the valve body and connection points can help prevent air leaks and ensure consistent braking performance throughout the vehicle's service life.
