I9981205T Safety Valve for Knorr-Bremse Systems

What does a compressor safety valve do?

This compressor safety valve plays a critical role in the pneumatic braking system by automatically venting excess air the moment pressure exceeds safe limits. By preventing overpressure, it protects the compressor housing, air lines, and reservoirs from potential damage, ensuring the integrity of the entire braking circuit.

Vehicle and system compatibility

This component is compatible with Knorr-Bremse systems and is designed for use in heavy commercial vehicle air brake compressors. It provides essential protection by maintaining pressure within safe operating parameters during intensive service conditions.

Technical specifications and installation

Designed with high-strength components, this valve features an M26 port connection and is rated for 17 BAR. Technicians should ensure that the threaded connection to the compressor housing is secure and check for any debris in the port during installation to maintain optimal venting performance.

Maintenance and troubleshooting

Regular inspection of the valve is recommended to ensure it continues to vent correctly when pressure thresholds are reached, preventing system-wide overpressure issues.
