301.07.0029 Pressure Limiting Valve — WABCO

The heavy-duty pressure limiting valve is a critical component designed to regulate pneumatic pressure within the braking system of heavy commercial vehicles. Engineered with high-strength components, this part ensures precise control over the pressure regulation process, maintaining system stability under demanding driving conditions.

301.07.0029 is the OE-equivalent of the WABCO 475 010 300 0 pressure limiting valve used in DAF, MAN, LEYLAND, LANGENDORF, and other heavy-duty vehicle systems. This component is engineered to meet exact specifications for compatibility with WABCO systems and various heavy commercial vehicle brands including Volvo, Scania, and Mack.

Maintenance of the pneumatic braking system requires precision and regular checks to ensure optimal performance. This valve features M22x1,5 VOSS ports for secure and reliable connection to the air lines. Workshop technicians should verify the adjustment range between 5,8 and 10,8 BAR to ensure the outlet pressure remains at the intended 8,5 BAR for safe operation.

Proper installation of this pressure limiting valve prevents pressure fluctuations that could impact braking reliability. By using high-grade components, maintenance teams can ensure long-term durability in heavy-duty transport applications.
