301.07.0054 Pressure Limiting Valve for Volvo

What does a pressure limiting valve do?

This pressure limiting valve acts 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, ensuring that auxiliary circuits or secondary components receive only the required air pressure regardless of the inlet pressure levels.

Compatible vehicles and engines

This component is engineered for high-performance compatibility with various heavy commercial vehicle models, including Volvo FH series, FM series, and Renault Trucks Kerax or Magnum models. It is also fitted to Mack Granite and Pinnacle trucks, providing reliable regulation for their pneumatic systems.

Technical specifications and installation

The unit features M16x1.5 port sizes and an adjustment range of 1.2 to 1.8 BAR to ensure precise control. For optimal performance, technicians should verify that the inlet pressure remains at 8 BAR and check the safety pressure threshold of 3.2 BAR during routine inspections to prevent system overpressure.

Maintenance and troubleshooting

Regular inspection of the valve helps prevent uneven braking or air system instability in heavy-duty applications. Consult your authorized distributor for more information regarding installation and system integration.
