301.07.0173 WABCO Compatible Pressure Limiting Valve

The pressure regulation within the brake system is critical for heavy vehicle safety and stability. This pressure limiting valve is designed to maintain precise pneumatic control, ensuring consistent performance under varying load conditions. Built with heavy-duty grade materials, it provides reliable pressure modulation to protect the pneumatic circuit from extreme fluctuations.

301.07.0173 is the OE-equivalent of the WABCO 434 100 222 0 pressure limiting valve used in DAF, EVOBUS, GOLDHOFER, IRISBUS, IVECO, KÖGEL, LIEBHERR, LOHR, MAN, MERCEDES BENZ, NEOPLAN, NISSAN UD TRUCK, PACCAR, RENAULT TRUCKS, SCANIA, SOLARIS, STEYR, and VOLVO systems. This component ensures seamless integration with high-standard brake-suspension hardware.

For workshop technicians, this valve features M22x1.5 threading on both ports for a secure connection. It is essential to check the pressure thresholds (6.2-0.3 Bar) and the limited return functionality during routine maintenance to prevent system failures. Proper installation ensures the longevity of the pneumatic braking components in heavy commercial vehicles.

Maintaining the braking system with high-strength components like this valve helps prevent unexpected pressure drops in the air lines. It is a vital part for ensuring that the pneumatic regulation remains within the designated operational limits of the vehicle's braking architecture.
