Description
What does a pressure limiting valve do?
This pressure limiting valve plays a critical role in regulating air pressure within the braking and suspension systems of heavy commercial vehicles. By utilizing a piston-and-spring mechanism, it opens at a specific threshold to vent excess air, ensuring that system pressures remain within safe operating limits. This component is manufactured using high-strength components to withstand demanding pneumatic environments.Compatible vehicles and engines
The unit is engineered for compatibility with various heavy-duty applications, including DAF, MAN, Mercedes-Benz, and VDL trucks. It is also designed to work with systems from WABCO and Provia. This part is essential for maintaining stable air pressure in tractor units and buses across these major vehicle brands.Installation and maintenance
Installation requires careful attention to the M22x1.5 VOSS port connections to ensure a secure seal. Technicians should verify that the inlet pressure of 10 BAR and the outlet pressure of 7 BAR align with the specific requirements of the vehicle's pneumatic circuit during replacement to ensure optimal braking performance.Troubleshooting guidance
Regular inspection of the valve is recommended to prevent pressure fluctuations in the braking system. If air leakage or inconsistent pressure regulation is detected, replacing the component with a high-quality equivalent can restore system integrity. Consult your authorized distributor.OE cross-reference
