Description
The 4-circuit protection valve is a critical component within the pneumatic brake system, ensuring the stable distribution of air pressure across multiple circuits. This component plays a vital role in maintaining system integrity and ensuring the safety of heavy commercial vehicles during operation.
The VADEN ORIGINAL 303.02.0085 is the OE equivalent of the VOLVO 8152899 and KNORR-BREMSE AE4428 used in various heavy-duty applications. This specific part is designed for compatibility with Volvo models such as F10 (TD102), F12 (TD122), FL10 (D10A), and B12 (D12A). It serves as a reliable replacement to ensure consistent pneumatic performance.
Technical specifications include a main port of M22x1,5 and secondary ports with M16x1,5 threading. The valve operates with specific opening pressures: 6,8 BAR for ports 21, 22, and 24, and 7 BAR for port 23. Closing pressures are set at 3,8 BAR for most circuits and 5,5 BAR for port 23 to ensure rapid system response.
For workshop technicians, it is essential to verify the port thread sizes and pressure settings before installation to ensure full system compatibility. Regular inspection of the pneumatic lines connected to this valve can prevent unexpected pressure drops in the brake system.
