Description
This high-strength component serves as a critical safety element within the pneumatic brake system of heavy commercial vehicles. As a precision-engineered 4-circuit protection valve, it manages air pressure distribution across multiple circuits to ensure operational stability and safety during transit.
303.02.0099 is the OE-equivalent of the WABCO 934 714 110 0 4-circuit protection valve used in MERCEDES BENZ, SCANIA, MAN, IVECO, and OTOKAR vehicles. This part is engineered to meet strict technical requirements for brands including ALEXANDER DENNIS, FAUN, KING LONG, and LEYLAND.
Workshop technicians should note the specific port configurations and pressure thresholds for precise installation. The unit features Port 1 (M22x1,5) and four secondary ports (M16x1,5). It is designed for seamless integration into existing pneumatic brake architectures to maintain consistent pressure regulation across all active circuits.
The component is built with heavy-duty grade materials to withstand the rigorous demands of long-haul transport and heavy-duty braking environments. Regular inspection of port connections and pressure thresholds ensures the longevity of the entire pneumatic system.
