I99812R Compressor Safety Valve for Knorr-Bremse Systems

What does a compressor safety valve do?

This compressor safety valve serves as a critical protection component within the pneumatic brake 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.

Compatibility and system integration

Designed for heavy commercial vehicle applications, this component is compatible with Knorr-Bremse systems. It ensures that the pressure generated by the air brake compressor remains within safe operational limits, maintaining system integrity during intensive use.

Technical specifications and installation

This specific unit features a 17 BAR pressure rating and an M26 threaded port connection. The high-strength components are engineered to withstand high-pressure environments and provide reliable mechanical opening and closing via a calibrated spring mechanism.

Maintenance and troubleshooting

To ensure proper function, technicians should inspect the valve for debris or leaks during routine maintenance intervals. Consult your authorized distributor to ensure this specific valve matches your compressor's requirements.
