303.04.0021 ECAS Solenoid Valve - Mercedes Benz

The 303.04.0021 ECAS Solenoid Valve is an essential component within the pneumatic suspension control system, designed to manage airflow with high precision. It operates at a pressure of 20 BAR and features four M22x1,5 VOSS ports (Ports 11, 21, 22, and 23) to ensure stable pneumatic transitions. The integrated silencer and specialized Bayonet DIN 72585 A1-4.1-Sn/K2/24V electrical connection provide the necessary reliability for heavy-duty operation.

303.04.0021 is the OE-equivalent of the Mercedes Benz 000 327 67 25 ECAS Solenoid Valve used in various heavy commercial vehicle applications including Scania and MAN models. This high-strength component is also compatible with several other leading manufacturers such as DAEWOO (3425002880), FORD (4C46 3038 AA), FOTON (1618029600001), MITSUBISHI (MK432443), RENAULT TRUCKS (5010143096), and WABCO (472 880 001 0). It serves as a critical replacement for many premium heavy-duty vehicle fleets.

For workshop technicians, this solenoid valve offers a seamless assembly process thanks to its standardized port sizes and robust electrical interface. Regular inspection of the pneumatic connections and ensuring the integrity of the M22x1,5 VOSS ports is recommended during routine suspension maintenance to prevent system leaks or pressure drops in the electronic controlled air suspension system.
