Description
The precision engineered 4-circuit protection valve ensures optimal pneumatic distribution within the braking system of heavy commercial vehicles. This component is designed to maintain constant pressure regulation across multiple circuits, providing essential safety and reliability during operation under varying load conditions.
The VADEN ORIGINAL 303.02.0073 is the OE equivalent of the KNORR-BREMSE AE4168, I75300, and K019911N00 used in Mercedes-Benz 0014315906 and VOLVO 1130617/1593150 systems. This high-strength component is compatible with various heavy-duty models including VOLVO F12 TD122, FL12 TD123, and B12 D12A series vehicles. It serves as a critical pressure regulator for the braking infrastructure.
Technical specifications include a Port 1 size of M22x1,5 and secondary ports (21, 22, 23, 24) measuring M16x1,5 each. The valve operates with an opening pressure of 6,5 BAR and a closing pressure of 4 BAR across all four circuits to ensure stable pneumatic control. Maintenance technicians should regularly check port connections and seal integrity to ensure optimal system performance.
This part is specifically engineered for professional workshop applications requiring high durability in the brake system environment.
