Description

What does a pressure limiting valve do?

This pressure limiting valve plays a critical role in maintaining stable air pressure within the pneumatic systems of heavy commercial vehicles. By utilizing a piston-and-spring mechanism, it manages excess air to ensure the system operates within safe parameters, protecting downstream components from overpressure conditions.

Vehicle and system compatibility

This component is compatible with Mercedes-Benz, MAN, Neoplan, and Lohr vehicles. It is engineered to meet the rigorous demands of heavy commercial vehicle air brake and air suspension systems, ensuring reliable performance across diverse operating environments.

Installation and maintenance guidance

For proper installation, technicians should verify the M22x1.5 VOSS port connections and ensure the adjustment range between 5.8 and 10.8 BAR matches the vehicle specifications. Regular inspection of the valve during routine maintenance can prevent system fluctuations and ensure optimal braking performance.

Selection guidance

Consult your authorized distributor to confirm exact fitment for your specific vehicle model.
