301.07.0172 WABCO Pressure Limiting Valve

The heavy-duty grade Pressure Limiting Valve is engineered to maintain optimal pneumatic regulation within the braking system. Designed for high-strength performance, this component ensures consistent pressure regulation under demanding heavy commercial vehicle conditions, providing essential stability and reliability for the braking circuit.

301.07.0172 is the OE-equivalent of the WABCO 434 100 221 0 Pressure Limiting Valve used in DAF, EVOBUS, IKARBUS, IVECO, LOHR, MAN, MERCEDES BENZ, VAN HOOL, and VOLVO systems. This part is specifically engineered to meet the rigorous standards required by these major vehicle manufacturers and their compatible braking architectures.

For workshop technicians, this component features standard M22x1.5 threading on both Port 1 and Port 2 to ensure a secure and precise fit during assembly. Regular inspection of the pressure threshold (5-0.3 Bar) and ensuring the limited return function remains operational is recommended during routine brake system maintenance to prevent system imbalances.

Maintaining the integrity of the pressure limiting function is vital for heavy commercial vehicle safety. This part provides a robust solution for managing pneumatic fluctuations, ensuring that the brake system operates within specified parameters across various load conditions.
