Description

What does a pressure limiting valve do?

This pressure limiting valve plays a critical role in maintaining the stability of pneumatic systems within heavy commercial vehicles. By utilizing a piston-and-spring mechanism, it manages air distribution to ensure that pressure levels remain within safe operational thresholds, preventing system overpressure during braking or suspension adjustments.

Vehicle and system compatibility

This component is specifically engineered for use in DAF, Iveco, and Renault Trucks. It is also compatible with WABCO systems, ensuring high-performance integration within the vehicle's pneumatic circuit. The unit features an outlet pressure of 7.5 BAR (+ 0.4 BAR) and a safety pressure threshold of 10.0 BAR to protect the integrity of the air brake system.

Installation and maintenance

For professional workshop technicians, proper installation is vital to ensure the M16x1.5 ports are seated correctly without leaks. Regular inspection of the adjustment range—typically between 4.0 and 8.0 BAR—is recommended during routine maintenance intervals to ensure optimal air pressure regulation throughout the pneumatic circuit.

System performance and safety

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