301.07.0189 WABCO Pressure Limiting Valve Compatible

The heavy-duty Pressure Limiting Valve is a critical component in the pneumatic braking system, ensuring regulated air pressure distribution within the circuit. This part is engineered to provide stable performance under demanding conditions, maintaining consistent pressure regulation to support vehicle safety and braking reliability.

301.07.0189 is the OE-equivalent of the WABCO 434 100 251 0 pressure limiting valve used in SCANIA and VAN HOOL heavy commercial vehicles. This component is specifically designed to integrate seamlessly with WABCO brake-suspension systems, ensuring that the pneumatic pressure remains within the required operational thresholds for safe braking maneuvers.

For workshop technicians, this valve features an M22x1.5 port specification, facilitating a precise and secure assembly during maintenance or replacement. It is essential to check for any air leaks or pressure inconsistencies during service intervals to ensure the long-term integrity of the braking system. Regular inspection of the port connections and the return functionality is highly recommended for fleet maintenance.

This part is manufactured using high-strength components to withstand the rigorous vibrations and thermal changes typical of heavy commercial vehicle environments. By utilizing this high-grade valve, technicians can ensure that the pressure regulation remains stable even during extreme load variations.
