303.04.0026 ECAS Solenoid Valve — VOLVO

The heavy-duty ECAS Solenoid Valve is a critical component within the pneumatic control system of modern suspension architectures. Designed to manage air distribution with precision, this component ensures consistent pressure regulation and reliable operational control under demanding heavy commercial vehicle environments.

303.04.0026 is the OE-equivalent of the VOLVO 20514451 and WABCO 472 880 023 0 ECAS Solenoid Valve used in compatible heavy-duty suspension systems. This part provides seamless integration with original equipment specifications to maintain optimal vehicle stability and air management functionality.

For the workshop technician, this solenoid valve features four specialized ports (11, 21, 22, and 23) all utilizing M22x1,5 VOSS connections for secure and leak-free assembly. It is engineered to operate effectively at a pressure of up to 20 BAR, making it a reliable choice for maintaining electronic air suspension systems in trucks and buses.

Regular inspection of the pneumatic lines and port seals is recommended during routine service intervals to ensure the valve continues to function within its designed parameters. Using high-strength components like this one helps prevent system failures and ensures long-term reliability in professional fleet maintenance.
