301.07.0057 Pressure Limiting Valve for Volvo & Renault

What does a pressure limiting valve do?

This pressure limiting valve plays a critical role in the pneumatic regulation of heavy commercial vehicle air brake systems. By utilizing a high-strength component design, it ensures stable air pressure management across various operating conditions to maintain braking efficiency. The unit is built to withstand the rigorous demands of heavy-duty service cycles.

Compatible vehicles and engines

This component is engineered for a wide range of heavy commercial vehicles, specifically fitting Volvo models such as the FH12, FH13, FM11, FM12, and FM13, as well as the VNL and VHD series. It is also compatible with Renault Trucks models like the Premium, Magnum, and Kerax. Additionally, it is fitted to Mack Granite and Pinnacle trucks. It works reliably within systems compatible with WABCO and DAF.

Installation and maintenance

The valve features M16x1.5 port sizes for both inlet and outlet connections. Technicians should verify that the inlet pressure remains at 11 BAR and monitor the adjustment range between 4.0 and 8.0 BAR during routine inspections to ensure optimal system performance. Proper installation ensures the safety pressure of 8.5 BAR is maintained correctly.

System performance and maintenance

Regular maintenance of the pneumatic circuit helps prevent premature wear of the internal spring mechanism. When replacing this part, ensure all connections are secure to maintain the integrity of the air brake system.
