Description

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. By rapidly venting compressed air from the brake chambers the moment the pedal is released, it eliminates the lag caused by long air lines and ensures the immediate disengagement of brake linings. This component is manufactured using high-strength components to withstand demanding operating conditions.

Compatibility and technical specifications

This specific unit is designed for use in MAN vehicles. It features a configuration with M22x1.5 Port 1, two M22x1.5 ports for Port 2, and an M22x1.5 Port 3, supporting a maximum pressure of 12 BAR. It is engineered to meet the rigorous requirements of heavy-duty braking circuits.

Installation and maintenance

For workshop technicians, proper installation involves ensuring all M22x1.5 threaded connections are secure to prevent air leaks. Regular inspection of the valve body and port integrity is recommended to maintain optimal braking performance and prevent delays in air release during service intervals.

Troubleshooting guidance

Consult your authorized distributor.
