301.07.0019 Volvo Compatible Quick Release Valve

What does a quick release valve do?

This quick release valve serves as a critical component within the pneumatic brake system of heavy commercial vehicles, designed to rapidly vent compressed air from brake chambers the moment the brake pedal is released. By reducing the air lag caused by long pneumatic lines, it ensures immediate lining disengagement, which improves braking response and overall safety.

Vehicle and engine compatibility

This component is specifically engineered for Volvo models including F10, F12, F7, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12. It is also compatible with several other heavy-duty makes such as DAF, Iveco, Scania, and Renault Trucks. The unit features a G 1/2" PTF main port and multiple G 3/8" NPTF ports to facilitate precise air distribution.

Installation and maintenance

When replacing this valve, technicians should verify that the port sizes and pressure ratings match the existing installation requirements. This part is rated for a maximum pressure of 10 BAR. Ensuring a clean connection during installation helps maintain the integrity of the pneumatic circuit and prevents air leaks that could affect braking efficiency.

Troubleshooting and selection

Regular inspection of the valve and its connections can help prevent uneven brake wear and ensure consistent braking performance across the axle.
