303.08.0006 Complete, EBS Relay Valve — WABCO

The 303.08.0006 Complete, EBS Relay Valve is a critical component within the electronic braking control systems of heavy commercial vehicles. This part ensures precise pneumatic response and maintains system stability during deceleration, providing essential reliability for long-haul transport and heavy-duty operations.

303.08.0006 is the OE-equivalent of the WABCO 480 202 004 0 EBS Relay Valve used in various heavy commercial vehicle systems including Mercedes-Benz, DAF, MAN, Scania, and Volvo architectures. This component is specifically engineered to meet the strict requirements of manufacturers such as DAF (1315686, 361623, 375215, 410323), MERCEDES BENZ (004 429 86 44, 005 429 12 44, 005 429 69 44), HINO (446000096A), and PACCAR (1505280, 1505288).

For workshop technicians, this unit is designed for straightforward integration into existing brake-suspension systems. It maintains high-strength performance under pressure fluctuations and ensures seamless communication between the EBS control unit and the pneumatic actuators. Regular inspection of the valve seating and air supply lines is recommended to ensure optimal braking response.

This specialized valve is essential for maintaining the integrity of the electronic braking signal path, preventing delays in brake application across complex heavy vehicle fleets.
