301.07.0018 Quick Release Valve for DAF and Scania

What does a quick release valve do?

This quick release valve plays a critical role in the pneumatic brake system of heavy commercial vehicles by rapidly venting compressed air from the brake chambers. By reducing the air lag within the lines, it allows the brake linings to disengage instantly when the pedal is released, which is essential for maintaining consistent braking performance and safety.

Vehicle and system compatibility

This component is designed for use in heavy-duty trucks, tractor units, and buses from Mercedes-Benz, Scania, DAF, and Renault Trucks. It is also compatible with WABCO systems. Before installation, technicians should verify the port configuration to ensure it matches the existing pneumatic circuit.

Technical specifications and installation

The unit features specific connection points including one G 3/8" J port and two G 3/8" J ports, with a maximum operating pressure rating of 10 BAR. For optimal performance, ensure all connections are secure and that no debris enters the ports during assembly to prevent leaks or delayed venting.

Maintenance and troubleshooting

Regular inspection of the valve body and connections can help prevent brake lag or uneven braking between wheels. Consult your authorized distributor for fitment verification.
