Description
The braking system relies on precision components to ensure safety and stability during heavy-duty operations. This 4-circuit protection valve serves as a critical regulator within the pneumatic circuit, managing air pressure distribution across multiple lines to maintain consistent braking performance.
The 303.02.0104 is the OE equivalent of the MAN 81521516098 and NEOPLAN 8151516095 used in heavy commercial vehicles. It is also fully compatible with WABCO 9347144000 systems. This component is engineered to meet strict technical requirements for pressure regulation and durability in demanding environments.
Technical specifications include M22x1,5 Voss ports for ports 1, 21, 22, 23, and 24. The device operates with an opening pressure of 6,9 BAR for circuits 21 and 22, and a specialized opening pressure of 7 BAR for circuit 23, ensuring precise pneumatic control for the vehicle's braking architecture.
Maintenance technicians should regularly inspect these valves for any signs of pressure leakage or performance drops in the pneumatic lines. Ensuring the correct installation of this protection valve is essential for the long-term reliability of the vehicle's air brake system.
