Description
What does a pressure limiting valve do?
This pressure limiting valve serves as a critical component within the pneumatic brake system, regulating air pressure to ensure optimal braking performance. By maintaining specific pressure thresholds, it prevents over-pressurization and ensures the stability of the braking circuit under various load conditions.System compatibility and application
The unit is designed to be compatible with Knorr-Bremse systems, providing a reliable solution for heavy commercial vehicle maintenance. It functions effectively within complex pneumatic networks, ensuring that the system maintains the required operating parameters during transit.Installation and maintenance guidance
Installation requires careful attention to the M22x1.5 port connections to prevent air leaks. Technicians should verify that the transition pressure remains at 4.0 BAR ± 0.2 BAR and check the safety pressure threshold of 5.5 BAR ± 0.5 BAR during routine inspections to ensure the integrity of the braking system.Operational monitoring
Regular monitoring of valve performance can prevent unexpected system failures. When replacing this component, ensure all connections are secure and that the pneumatic lines are free from contaminants that could interfere with the internal spring mechanisms.OE cross-reference
301.07.0088 (Pressure Limiting Valve) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number AC157B.Technical Specifications
