301.07.0044 Compatible Pressure Limiting Valve

What does a pressure limiting valve do?

This pressure limiting valve acts as a vital mechanical control element within the air brake circuit of heavy commercial vehicles. It functions by regulating the output pressure of specific lines to a predetermined upper value, preventing excessive pressure from reaching sensitive components. Built with high-strength components, it ensures reliable performance even under the demanding conditions of heavy-duty service.

Compatible vehicles and engines

This component is widely used in various heavy commercial vehicle models, including Volvo FH, FM, and VNL series, as well as Mack Granite and Pinnacle. It is also compatible with Renault Trucks models like Kerax and Premium. This part is further fitted to Iveco, MAN, Mercedes-Benz, and Scania trucks.

Installation and maintenance

Installation requires careful attention to the M16x1.5 port connections to ensure a secure seal. Technicians should verify that the inlet pressure remains within the 10 BAR specification and that the adjustment range is set correctly between 4.0 and 8.0 BAR to maintain optimal braking performance. Regular inspection of the valve helps prevent system pressure fluctuations.
