Description

What does a safety valve do?

This compressor safety valve serves as a critical pressure relief component within the pneumatic braking system. It functions by automatically venting excess air the moment pressure in the air brake compressor exceeds safe limits, protecting the compressor housing, air lines, and reservoirs from damage caused by overpressure.

Technical specifications and compatibility

This component is engineered to be compatible with Knorr-Bremse systems. It features a 17 BAR pressure rating and an M26 thread size to ensure precise fitment and reliable operation during heavy-duty service cycles.

Installation and maintenance

For proper maintenance, technicians should check the valve during routine brake system inspections. Ensure the M26 threaded connection is seated correctly on the compressor housing to prevent leaks and maintain consistent pressure regulation. Consult your authorized distributor for installation guidance.

System protection benefits

Selecting a valve that matches the specific requirements of the pneumatic system is vital for road safety and preventing costly system failures.
