301.07.0042 Pressure Limiting Valve compatible with Renault Trucks

What does a pressure limiting valve do?

A pressure limiting valve is a mechanical control element in the air brake circuit of heavy commercial vehicles that keeps the output pressure of a specific line at a predetermined upper value, independent of the inlet pressure. This component is essential for protecting auxiliary circuits from excessive air pressure, ensuring that sensitive pneumatic components operate within safe limits.

Compatible vehicles and engines

This valve is compatible with Volvo models including FH12, FH13, FH16, FM series, FMX, and VNL, as well as Renault Trucks Kerax, Magnum, and Premium. It also fits Mack Granite and Pinnacle units. The component is engineered to function reliably within these heavy-duty air brake systems.

Technical specifications and installation

The unit features M16x1.5 ports and is designed to manage an inlet pressure of 8 BAR, providing an outlet pressure of 5.3 BAR ± 0.2 BAR with a safety pressure threshold of 7.6 BAR. For proper installation, technicians should ensure all connections are secure to maintain the integrity of the pneumatic circuit.

Maintenance and troubleshooting

Regular inspection of the valve can help prevent system imbalances. If a vehicle experiences inconsistent braking performance or air leakage in secondary circuits, checking this component is a recommended maintenance step. Check the compatibility list.
