301.07.0051 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 maintains the output pressure of specific lines at a predetermined upper value, independent of the inlet pressure, to protect auxiliary circuits and brake chambers from excessive pneumatic force.

Vehicle compatibility and engine fitment

The component is engineered for high-performance fitment in various heavy-duty models, including Volvo FH12, FH13, FM series, and Renault Trucks Kerax and Magnum. It is also fitted to DAF and Iveco trucks. This valve operates effectively within systems requiring an adjustment range between 4.0 and 8.0 BAR to ensure consistent braking performance.

Installation and maintenance guidance

Installation should be conducted by a workshop technician to ensure proper alignment of the M16x1,5 ports. Maintaining the correct safety pressure of 9.2 BAR is vital for system integrity. Regular inspection of the valve helps prevent pressure fluctuations in the air brake and suspension lines.

System performance and selection

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