303.05.0001 Trailer Control Valve — WABCO Compatible

The heavy-duty Trailer Control Valve is a critical component within the pneumatic brake system of heavy commercial vehicles, ensuring stable air pressure regulation and control. Designed with high-strength components, this part provides reliable performance under demanding industrial conditions to maintain optimal braking functionality.

303.05.0001 is the OE-equivalent of the WABCO 973 002 000 0 Trailer Control Valve used in DAF, FORD, IVECO, MAN, MERCEDES BENZ, and NOOTEBOOM vehicle systems. This part is engineered to meet strict technical standards for compatibility with systems from IVECO (00000668, 004731117, 008790482, 61577722), MAN (82.52301-600 much like 82.52301-6000 or 99.01436-0901), and MERCEDES BENZ (001 431 04 05).

For workshop technicians performing maintenance or repairs, this valve features five specialized M22x1,5 ports: Port 1, Port 2, Port 41, Port 42, and Port 44. Proper installation and regular inspection of the pneumatic connections are essential to ensure the longevity of the braking circuit in trucks and buses. This component is specifically designed for heavy commercial vehicle applications and is not suitable for light-duty vehicles.

Maintaining system integrity requires verifying that all port connections are secured according to technical specifications to prevent air leaks in the control circuit.
