Description

The 303.02.0002 Multi-circuit Protection Valve serves as a vital safety component within the pneumatic braking system of heavy commercial vehicles. Its primary function is to regulate air pressure across multiple circuits, ensuring that any failure or pressure drop in one circuit does not compromise the entire system. Constructed with high-strength components, this valve provides reliable circuit isolation and pressure stability for long-haul operations.

This part is the OE-equivalent of the MERCEDES BENZ 003 431 55 06 Multi-circuit Protection Valve used in various heavy duty vehicle systems including EVOBUS, FAUN, and KENWORTH models. It also serves as a direct replacement for WABCO 934 705 002 0 and FAUN 99707005559 specifications, ensuring seamless integration with existing braking hardware and pneumatic architectures.

For workshop technicians, the installation requires precision regarding the specific port configurations. The valve features several M22x1,5 ports (Ports 1 through 26) and two M12x1,5 ports (Ports 27 and 28). Technical monitoring should focus on the opening pressure for circuit 22/24 at 7,5 BAR and the closing pressure for circuits 21/22 at 7 BAR to ensure the system maintains peak operational safety during service intervals.
