301.07.0039 Pressure Limiting Valve

The heavy duty Pressure Limiting Valve is a critical component designed to regulate air pressure within the brake system of heavy commercial vehicles. This part ensures stable pneumatic control by managing the pressure transition between the inlet and outlet ports. Engineered with high-strength components, it maintains consistent operation under demanding industrial conditions.

301.07.0039 is the OE-equivalent of the WABCO 475 015 004 0 Pressure Limiting Valve used in DAF, IVECO, MAN, MERCEDES BENZ, SCANIA, and VDL systems. This technical component is also compatible with a wide range of heavy commercial vehicle brands including Freightliner, Kenworth, Mack, Peterbilt, and Volvo to ensure precise pressure regulation.

Workshop technicians should ensure that the port connections (M16x1,5) are properly seated to prevent air leaks. The valve is calibrated for an adjustment range of 3,5 to 4,5 BAR with a security pressure of 5,6 BAR. Regular inspection of the seal integrity and port surfaces during brake system maintenance is recommended to ensure optimal performance and safety in heavy-duty transport applications.
