301.07.0077 Pressure Limiting Valve compatible with Volvo

What does a pressure limiting valve do?

This pressure limiting valve serves as a critical mechanical control element within the air brake circuit of heavy commercial vehicles. It functions by maintaining the output pressure of specific lines at a predetermined upper value, regardless of the inlet pressure fluctuations. This ensures that auxiliary circuits or specific brake chambers receive regulated air levels to prevent system over-pressurization.

Vehicle and engine compatibility

This component is engineered for compatibility with a wide range of heavy-duty vehicles including Volvo FH, FM, and VNL series, as well as Renault Trucks models like Kerax and Premium. It is also fitted to Mack Granite and Pinnacle trucks. The valve operates effectively within these complex pneumatic systems to maintain stable air distribution.

Technical specifications and installation

The unit features M22x1,5 ports and is designed to manage an inlet pressure of 7,5 BAR with an adjustment range between 1,2 and 6,2 BAR. For optimal performance, technicians should inspect the valve for air leaks or improper pressure regulation during routine brake system maintenance. Ensuring correct port alignment during installation is essential for maintaining system integrity.

Maintenance guidance

Consult your authorized distributor to confirm exact fitment for your specific engine configuration, such as Volvo D13 or Renault DXi series.
