301.07.0039 Pressure Limiting Valve for Mercedes-Benz

What does a pressure limiting valve do?

This pressure limiting valve plays a critical role in the air brake system of heavy commercial vehicles by regulating pneumatic pressure. It utilizes a piston-and-spring mechanism to maintain consistent air pressure levels, ensuring the safety and reliability of the braking system under heavy-duty conditions.

Vehicle and system compatibility

This component is compatible with Mercedes-Benz, MAN, Scania, DAF, Iveco, Neoplan, and VDL vehicles. It is also designed to work reliably with WABCO systems to maintain optimal pneumatic performance across various heavy commercial vehicle applications.

Installation and maintenance guidance

Installation requires attention to the M16x1,5 port specifications to ensure a secure connection within the air circuit. Technicians should verify that the outlet pressure remains within the specified 3.5 BAR (+0.2 BAR) range during routine inspections to prevent system imbalances.

System monitoring and selection

Regular maintenance of the pneumatic circuit helps prevent premature wear of the valve's internal components. Monitoring the adjustment range of 3.5 to 4.5 BAR is essential for maintaining correct braking response and safety thresholds in heavy-duty service environments.
