I99812 Compressor Safety Valve for Knorr-Bremse systems

What does a compressor safety valve do?

This compressor safety valve plays a critical role in protecting the pneumatic brake system by automatically venting excess air when pressure exceeds safe limits. By preventing overpressure, it protects the compressor housing, air lines, and reservoirs from potential damage. This component is manufactured using high-strength components to withstand demanding operating conditions.

Compatibility and application

This part is compatible with Knorr-Bremse systems and is suitable for various heavy commercial vehicle applications. It is designed to integrate seamlessly into existing pneumatic circuits to maintain system integrity.

Installation and maintenance

Maintenance technicians should ensure the M26 port connection is properly seated and that the 17 BAR pressure threshold matches the specific requirements of the compressor unit. Regular inspection of the valve is recommended to prevent leaks or failure to vent.

System protection

Proper selection of this safety valve ensures that the air brake system operates within safe parameters, reducing the risk of component fatigue or system failure.
