303.04.0117 KNORR-BREMSE ECAS Solenoid Valve

The heavy-duty ECAS Solenoid Valve is a critical component within the pneumatic suspension control system of heavy commercial vehicles. Designed to manage air distribution precisely, this component ensures stable and reliable suspension adjustments during operation. Utilizing high-strength components, it maintains consistent performance under demanding road conditions and varying pressure levels.

303.04.0117 is the OE-equivalent of the KNORR-BREMSE 0501100038 ECAS Solenoid Valve used in heavy commercial vehicle suspension systems. This part is engineered for seamless compatibility with KNORR-BREMSE systems, ensuring that technical specifications such as the 13 BAR operating pressure and specific port sizes (Port 4: M12x1,5; Port 11/12/21/22: M16x1,5) are met for optimal integration.

For workshop technicians performing routine maintenance or system repairs, this solenoid valve offers a direct fit for electronic air suspension control modules. It is essential to verify the port configurations—specifically the four M16x1,5 ports at position 22—to ensure correct assembly and prevent pneumatic leakage. Regular inspections of the pneumatic lines and connections are recommended to maintain system integrity and prevent unexpected downtime in heavy-duty transport operations.
