Description
What does a pressure limiting valve do?
This pressure limiting valve plays a critical role in the air brake and air suspension systems of heavy commercial vehicles. By utilizing a precision piston-and-spring mechanism, it regulates air pressure by venting excess air once a specific threshold is reached. This ensures the stability and safety of the pneumatic system under varying load conditions.Vehicle and system compatibility
This component is compatible with DAF, Langendorf, Leyland, and MAN vehicles. It is also designed to work seamlessly with WABCO systems to maintain optimal pneumatic performance across the vehicle's braking circuit.Installation and maintenance guidance
Installation requires careful attention to the M22x1.5 VOSS port connections to prevent leaks. Technicians should verify that the inlet pressure of 10 BAR aligns with the system requirements and check that the outlet pressure remains within the specified 8.5 BAR range during routine maintenance intervals.Troubleshooting and selection
Regular inspection of the valve can help prevent sudden pressure drops in the braking system. When replacing old units, ensuring the adjustment range of 5.8 to 10.8 BAR matches the vehicle's original specifications is essential for maintaining system integrity.OE cross-reference
