301.07.0056 Pressure Limiting Valve — Volvo compatible

What does a pressure limiting valve do?

This pressure limiting valve is a vital mechanical component within the air brake circuit of heavy commercial vehicles. It functions by regulating the output pressure of specific lines to a predetermined upper limit, ensuring that auxiliary circuits or specific brake chambers are not exposed to excessive pressure levels regardless of the inlet pressure.

Compatible vehicles and engines

This component is specifically engineered for fitment in heavy-duty vehicles including Volvo FH series, FM series, and VHD models, as well as Renault Trucks Premium and Magnum series. It is also compatible with Mack Granite and Pinnacle models equipped with MP7 or MP8 engines. These parts are also fitted to DAF and Scania trucks.

Installation and maintenance

For reliable performance, technicians should verify that the port sizes match the M16x1,5 specifications during installation. Maintaining the correct adjustment range between 4.0 and 8.0 BAR is essential for system integrity. Regular inspection of the valve helps prevent pressure fluctuations within the pneumatic braking system.

System reliability

When replacing this component, ensure all connections are secure to maintain the integrity of the air circuit.
